Language and Identity: Code-Switching Practices among Multilingual Communities
Authors: Kipchoge Ruben
Published: July 2024

Purpose: This study sought to analyze code switching practices among multilateral communities.
Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library.
Findings: The findings reveal that there exists a contextual and methodological gap relating to language and identity. Preliminary empirical review revealed that code-switching was a strategic tool for navigating and negotiating identities. It highlighted the practice's role in maintaining cultural heritage, aiding social integration, and enhancing professional advancement. The study emphasized the importance of code-switching in preserving linguistic traditions and managing social relationships. It concluded by recommending more inclusive language policies and educational practices that recognize the value of code-switching as a legitimate communicative practice.
Unique Contribution to Theory, Practice and Policy: The Social Identity Theory, Communication Accommodation Theory and Ethnolinguistic Identity Theory may be used to anchor future studies on language and identity. The study recommended integrating Social Identity Theory with Communication Accommodation Theory for a holistic understanding of code-switching and suggested developing a new model to address language and identity interplay. In education, it advocated for translanguaging pedagogies and training for teachers to support multilingual students. In professional settings, it advised fostering language-inclusive environments and training programs to enhance linguistic awareness. Policy recommendations included implementing language policies that support multilingualism and linguistic rights. The study also emphasized promoting social integration through community programs and identified future research directions to further explore the relationship between language and identity.

O Evangelho Segundo Jesus Cristo, by Saramago: an anthroponomical reading
Authors: Eckert Kleber , Röhrig Maiquel
Published: July 2024

The subject of this paper is a symbolic and etymological analysis of the characters’ names from O Evangelho Segundo Jesus Cristo by José Saramago. This study aims to verify how the names are related to their functions in the literary work and to their physical or behavioral features. Additionally, it aims to determine whether the choice of their names was intentional and corresponds to their etymological origin or if it was merely fortuitous. The study is justified due to the book's and its author's relevance to the Portuguese language, besides, it is noted that, as far as has been determined, no publication has approached this matter. The theoretical foundation is based on Onomastics studies and, more specifically, on Fictional Anthroponomastics, which focuses on the study of proper names of fictional characters. Regarding the methodological procedures, the following procedure was considered: careful reading of the work and recording all occurrences related to proper names; consulting dictionaries of first and last names; verification of the correspondence between the meaning of the name as presented on the dictionaries and the functions and characteristics within the literary work. It is concluded that the choice of names in the case of the analyzed book was not fortuitous but rather etymological and symbolically motivated.

Management of Gridhrasi (Sciatica) using Panchkarma Therapies – A Case Study
Authors: Poriya Kanji K , Kumar Vipin
Published: July 2024

Low back pain is the most common complaint encountered by general practitioners. Chronic low back pain (CLBP)  prevalence increases linearly from the third decade of life on, until the 60 years of age, being more prevalent in  women. Sciatica is the most common debilitating condition causes CLBP. Radiating leg pain and related disabilities  are the observed in sciatica. Nearly 40% of people experience sciatic pain at some point in their life. The diagnosis of  sciatica and its management varies considerably within and between countries. Conventional Medicine and surgery  are widely used in the management of sciatica. There is a radical rise in the use of Complementary and Alternative  Medicine (CAM) in patients with sciatica. Sciatica resembles the disease Gridhrasi which is mentioned in Ayurvedic  classical text book which included under Vataja Nanatmaja Vikara. In Gridhrasi, pain starts from Kati-Prushta (pelvic  and lumbosacral region) radiating toward Jangha Pada (thigh and legs) with impairment of lifting leg (stiffness).  Ghridhrasi can be treated remarkably with procedures of panchakarma and internal medicine. Here in this case study,  a 55-year-old male patient was suffering from low back pain radiating toward posterior part of the left leg due to  disk desiccation with diffuse disc bulge is seen in MRI at L3-L4 and L4-L5 level and also seen a ligamentum flavum  hypertrophy and posterocentral extrusion is seen at L5-S1 level, indenting the anterior thecal sac and mild compression  on bilateral exiting nerve roots. He was treated with one course of Kala Basti followed by Bala Taila Aanuvasana Basti  and Erandmuladi Kwath Niruha Basti along with Patra Pinda Swedana and Prushtha Basti with Dashmoola Taila and  internal medicine. The patient showed improvement remarkably and could do all routine work properly.

Authors: Anshu  , Singh Sarvesh Kumar , Rajoria Kshipra
Published: July 2024

Introduction: First of all, Tinospora cordifolia, sometimes referred to as “Amrita” or “Guduchi,” is a crucial  medication utilized in Indian Systems of Medicine and has been for ages. The Sanskrit term “guduchi” means “which  protects the body from diseases.” This herb is also known by the name “Amrita,” which in Hindu mythology alludes  to the celestial nectar. Aim: This well-known Indian bitter is recommended for fevers, diabetes, dyspepsia, jaundice, skin conditions,  kidney issues, persistent diarrhea, and dysentery. Leprosy, helminthiasis, rheumatoid arthritis, and cardiac problems  have all been shown to benefit from it. It is a significant medication that is utilized in a variety of preparations,  including Swarasa, Ghrita, Satva, Tail, etc. Material and Methods: For this review article, Charaka Samhita, Sushruta Samhita, Ashtanga Hridaya, Ashtanga  Sangraha, Bhavprakash Nighantu, Raj Nighantu, Dhanvantari Nighantu, Shaligrama Nighantu, Priya Nighantu, Kaiydev Nighantu, Madanpal Nighantu, Shodhal Nighantu. Results: It has long been recognized that the T. cordifolia plant possesses strong therapeutic, medicinal, healing, and  soothing properties. Discussion: Guduchi’s anti-toxic, anti-inflammatory, antipyretic, and anti-oxidant qualities make it a highly  promising medicinal herb. In addition, there is no proof that Guduchi contains any harmful substances or adverse  effects, demonstrating its safety. Conclusion: T. cordifolia, often known as Giloy, is an herb with medicinal characteristics that can prevent many  diseases or abnormalities by naturally boosting immunity in human bodies. These properties are confirmed by the  therapeutic and safety aspects research included in this review. Herbal and traditional medicines have a long history and are widely  used in India. Natural medicines are becoming more and more  important in clinical research these days. In the enormous collection  of significant Guduchi (Tinospora cordifolia), one of the medicinal
Revisiting Cosa (Ansedonia, Italy): contributions of SAR-X images from the PAZ satellite to non-invasive archaeological prospecting
Authors: Fiz Fernández José Ignacio , Martín Serrano Pere Manel , Grau Salvat Maria Mercè , Cartes Reverté Antoni
Published: July 2024

Highlights:

Some archaeological results obtained using SAR-X images received through the PAZ satellite and applied to a part of what was called Ager Cosanus are shown in this article.
The study has been completed with the analysis of multispectral images TripleSAT and Sentinel-2A and the historical aerial photos from 1944 and 1954.
The possibilities of using PAZ images treated multi-temporally as a high-resolution panchromatic image applicable to multispectral optical images of the type Sentinel-2 were tested.

Abstract:
Some archaeological results are shown in this article, which have been generated from the use of Synthetic Aperture Radar (SAR)-X images obtained from the PAZ satellite and applied to part of what was called Ager Cosanus, that is, the territory of the city of Cosa, which was one of the first maritime colonies of Rome in the heart of Etruscan territory. Our study has been carried out mainly based on previous works in which a set of images was used to improve the quality of the resulting image, reducing the noise caused by the speckle of the radar images and maintaining the quality of the spatial resolution that can be obtained from these images (1.25 m/pixel). More specifically, a set of images obtained between 2019 and 2021 was used. The study has been completed with the analysis of multispectral images TripleSAT and Sentinel-2A, the historical aerial photos taken from 1944 and 1954, and the use of the historical cadastre of Tuscany, prepared at the beginning of the 19th century. As an addition, the Digital Terrain Model (DTM) Light Detection And Ranging (LiDAR) of the Region of Tuscany was used, on which various functions of the Relief Visualization Tool (RVT) programme have been applied, complementing or contrasting the results. It can be confirmed that the multi-temporal treatment of SAR PAZ images provides better results than an individualised analysis of the image. Finally, it is of great interest to verify the results of studies using new technologies, where it was previously possible to resort only to prospecting on the ground and to analogical aerial photography in black and white. In this case, the Sinistra Decumano I (SDI) structure was seen, which Castagnoli observed in the aerial photography, but of which he only located materials on the ground and it was visualised both in individualised PAZ images and in Sentinel-2.

La cerámica de Torre d’Onda (Burriana, Castellón) en el contexto de los establecimientos costeros del norte de la ciudad de Sagunto en época iberorromana
Authors: Benedito-Nuez Josep , Medina Gil Pablo , Melchor Monserrat José Manuel , Oliver Foix Arturo
Published: July 2024

Este trabajo se inscribe en el proyecto de investigación «Aplicación de nuevas técnicas y analíticas en el estudio del patrimonio arqueológico de Sagunto y la provincia de Castellón relacionado con la ocupación prerromana y romana como instrumento de gestión científica y turística» (UJI-A2020-01. Pla de Promoció de la Investigació a la Universitat Jaume I 2020), cuyo objetivo es conocer el cambio cultural producido en la población ibera edetana localizada al norte de la ciudad de Sagunto como consecuencia de la conquista romana. Durante este periodo se fue consolidando un modelo de dominio territorial romano, coincidiendo con la reconstrucción de la ciudad de Saguntum, que tras la finalización de la Segunda Guerra Púnica pasó de ser una ciudad aliada de Roma a ser una ciudad federada. Sin embargo, a pesar de que la presencia romana en esta región es bastante desconocida entre los siglos ii y i a. C., es bastante probable que Torre d’Onda formara parte de su área de influencia desde los primeros tiempos de conquista. La cerámica registrada en el yacimiento es un testimonio clave para reconstruir el final de esta etapa, cuya interpretación histórica ha estado condicionada por la escasez de información por parte de las fuentes escritas durante el siglo i a. C. y la falta de datos arqueológicos concretos sobre las guerras sertorianas, que hacían creer que las comunidades locales apenas se habían visto afectadas por este conflicto. Para alcanzar este conocimiento hemos considerado necesario estudiar, a través de los vestigios cerámicos que presentamos en este trabajo, algunas de las actuaciones que llevó a cabo Roma en estas tierras. De las excavaciones de Torre d’Onda procede un conjunto de vasos ibéricos pintados –algunos de ellos muy interesantes dentro del repertorio vascular ibérico–, cerámicas a mano y de cocina ibéricas, ánforas ibéricas, cerámica campaniense A, B y calena tardía, cerámica de cocina itálica, ánforas itálicas procedentes de la costa tirrénica y adriática, junto con otras de origen peninsular y cerámica gris bruñida que, debido a la propia naturaleza de los objetos analizados, a pesar de no contar con una estratigrafía publicada particularmente definitoria o esclarecedora, permiten afinar fechas con una precisión decenal y secuenciar el cambio histórico más importante de este yacimiento costero durante el primer tercio del siglo i a. C., entre el 90-70 a. C., ligado probablemente al desarrollo del episodio sertoriano.

Published: July 2024

Solar still owns low distillate productivity. Many researchers enhanced the performance of solar still by variable the design of its components. The combination of internal/external reflectors, absorber materials (fins, sponge, pebbles), and external condensers had a substantial impact on the absorption, evaporation, and condensation processes of the classic basin type solar still. This paper is showing how existing methods for increasing solar still absorption, evaporation, and condensation may be used to improve solar still absorption, evaporation, and condensation. From this review, it is found that for solar still, that adjusting the internal/external reflectors might increase daily distillate yield by 70% to 100%. Added Absorbent materials improve the thermal performance of a still by increasing production by over 20%. In addition, the external condensers enhanced still freshwater yield by 62% more than the regular still.
Private Equity in Transition: Co-Investments, ESG Integration and Digitalisation as Key Strategies for German SMEs
Authors: SCHERER Norman
Published: July 2024

Amidst economic uncertainties and geopolitical tensions, traditional debt financing instruments in the real estate and project development industry are losing appeal, leading to a surge in private equity (PE) as a promising financing alternative. This study examines the increasing significance of PE co-investment funds as financial instruments in an evolving market environment. Drawing from primary sources, including market data from Morningstar, Pitchbook, European Central Bank, and other referenced studies, the analysis sheds light on the reduced transaction activity of private equity in 2023 and the consequent adaptation strategies, such as the emergence of “continuation vehicles” and the pivotal role of co-investments. Additionally, a deep dive into Germany’s SME landscape reveals the transformative potential of PE in supporting businesses, particularly through the integration of ESG (environmental, social and governance) parameters and the promotion of digitalization. Through qualitative analysis and comprehensive data collection from both primary and secondary sources, the study underscores the fundamental role of private equity in the current business scenario, enabling companies to navigate challenges and implement vital transformations.

Hospitality and pet well-being in friendly hotels as a competitive advantage
Authors: Iamamoto Marcos Fabrizio , Delorence Rosalia , Wada Elizabeth Kyoko
Published: July 2024

The contemporary world has increasingly valued well-being, physical and mental health and how certain experiences can contribute to this. In this sense, hotel chains have invested in the pet friendly experience to create a competitive advantage in the face of new customer profiles, who value hospitality and personalization of service. Despite this being an expanding market, hospitality as a competitive differentiator through pet friendliness must be connected to providing customers with experiences that exceed their expectations. It is in this sense that this research aims to analyze whether hotel chains that support pet friendly operate, in this service segment, based on the principles of hospitality. This is a descriptive, qualitative research, carried out by reviewing the literature. The theoretical support was developed based on Guidara (2023), in addition to consulting studies published in the digital repositories Scientific Electronic Library Online – Scielo, Google Scholar and PubVet that bring the perspective of pet-friendly hospitality and its impacts on the hotel sector. With the research it was possible to understand that the concept of irrational hospitality is related to transcending traditional customer service, providing more than expected. It is considered that for the hotel industry, pet-friendly hospitality, following Guidara's (2023) theoretical approach, becomes a competitive advantage, generating a sense of belonging through memorable experiences. However, it was noted that large hotel chains, when offering pet friendly experiences, do not pay attention to the principles of hospitality, missing the opportunity for customer loyalty and competitive advantage.

The correlation between Arctic sea ice, cloud phase and radiation using A-Train satellites

Published: July 2024

Abstract. Climate warming has a stronger impact on Arctic climate and sea ice cover (SIC) decline than previously thought. Better understanding and characterization of the relationship between sea ice and clouds and the implications for surface radiation is key to improving our confidence in Arctic climate projections. Here we analyze the relationship between sea ice, cloud phase and surface radiation over the Arctic, defined as north of 60° N, using active- and passive-sensor satellite observations from three different datasets. We find that all datasets agree on the climatology of and seasonal variability in total and liquid-bearing (liquid and mixed-phase) cloud covers. Similarly, our results show a robust relationship between decreased SIC and increased liquid-bearing clouds in the lowest levels (below 3 km) for all seasons (strongest in winter) but summer, while increased SIC and ice clouds are positively correlated in two of the three datasets. A refined map correlation analysis indicates that the relationship between SIC and liquid-bearing clouds can change sign over the Bering, Barents and Laptev seas, likely because of intrusions of warm air from low latitudes during winter and spring. Finally, the increase in liquid clouds resulting from decreasing SIC is associated with enhanced radiative cooling at the surface. Our findings indicate that the newly formed liquid clouds reflect more shortwave (SW) radiation back to space compared to the surface, generating a cooling effect of the surface, while their downward longwave (LW) radiation is similar to the upward LW surface emission, which has a negligible radiative impact on the surface. This overall cooling effect should contribute to dampening future Arctic surface warming as SIC continues to decline.

Abstract. The response in cloud water content to changes in cloud condensation nuclei remains one of the major uncertainties in determining how aerosols can perturb cloud properties. In this study, we used an ensemble of large eddy simulations of marine stratocumulus clouds to investigate the correlation between cloud liquid water path and the amount of cloud condensation nuclei. We compare this correlation directly from the model to the correlation derived using equations which are used to retrieve liquid water path from satellite observations. Our comparison shows that spatial variability in cloud properties and instrumental noise in satellite retrievals of cloud optical depth and cloud effective radii result in bias in satellite-derived liquid water path. In depth investigation of high-resolution model data shows that in large part of a cloud, the assumption of adiabaticity does not hold which results in a similar bias in LWP-CDNC relationship as seen in satellite data. In addition, our analysis shows a significant positive bias of between 18 % and 40 % in satellite-derived cloud droplet number concentration. However, for the individual ensemble members, the correlation between the cloud condensation nuclei and the mean of the liquid water path was very similar between the methods. This suggests that if cloud cases are carefully chosen for similar meteorological conditions and it is ensured that cloud condensation nuclei concentrations are well-defined, changes in liquid water can be confidently determined using satellite data.
Integrated analysis of sediment connectivity and geomorphic effects of Storm Ciaran in two mountain catchments in Tuscany (Italy).

Published: July 2024

Extreme rainfall events over mountain catchments often trigger mass failures on hillslopes and sediment transport along the channel network. Understanding the connection between sediment sources and downstream transfer pathways is crucial in areas where settlements are impacted by hydro-geomorphic processes, to plan effective risk mitigation measures.From November 2 to 5, 2023, northern Tuscany (Italy) experienced a severe flood due to storm Ciarán, causing landslides and flooding. This disaster led to eight deaths, displaced 300 people, and caused around €1.9 billion in damages.This study focuses on two adjacent catchments, covering a total area of approximately 35 km2, within the area affected by the storm event. To analyse sediment dynamics at the catchment scale, an integrated approach was devised, encompassing the analysis of high-resolution (0.5 m) satellite imagery combined with the field-based mapping of hillslope instabilities. After the instabilities census, the analysis was integrated with an Index of Connectivity map (created using SedInConnect 2.3 software) to characterize pre-event structural connectivity in both catchments. The integration of these datasets enables the determination of the type, extent, and characteristics of mass movements providing sediments to the channel network, as well as understanding the interaction between sediment transport in the main channel and its morphological modifications. This finding highlights that inventory maps developed soon after extreme events, combined with sediment connectivity data, can provide vital information for future land management and risk mitigation. These insights can help prioritize structural interventions in specific areas to reduce connectivity or disconnect inhabited areas from hydro-geomorphic systems, thereby preventing future damage.The research is currently funded by the APPARE project within the framework of the Extended Partnership of the main project RETURN of the Italy’s Recovery and Resilience Plan (Next Generation EU). The APPARE project seeks to improve the understanding of flash floods in mountainous and hilly regions. This initiative aims to increase community resilience through better risk planning and management in these areas.
The peculiarities of Ianos among Mediterranean tropical-like cyclones
Authors: Nigro Daniele , Bordoni Simona , Giovannini Lorenzo , Miglietta Mario Marcello
Published: July 2024

Mediterranean tropical-like cyclones, also known as medicanes, are small cyclones observed in the Mediterranean region with an average frequency of 1-2 cases per year, mainly in autumn and winter. The tropical-like phase of these cyclones is characterized by the presence of a symmetric thermal structure and a deep warm core, which are features typical of tropical cyclones. Their mechanisms of formation and tropical transition have been investigated by many authors, but an official rigorous definition of medicane is still lacking, due to the significant case-by-case differences.In this work, 17 Mediterranean cyclones, including three potential medicanes in 2023, have been first analyzed using the ERA5 reanalysis dataset to evaluate their similarities and dissimilarities, considering different features in the lower and upper troposphere. Results show that the development of a warm core is negatively correlated with potential vorticity (PV) in the upper troposphere, while PV increases in the low troposphere due to latent heat release. It has also been verified that during the tropical-like phase the wind shear presents lower values, the jet stream is weaker and farther from the cyclone center, and the cyclone is vertically aligned, even if some exceptions exist. Then, the presence of a dry intrusion has been investigated using back-trajectories, showing that all cyclones present descending dry air associated with a PV streamer, meaning that the upper-level dynamics are fundamental in the early stages. However, the threshold of 400 hPa of descent in 48 hours used in literature to define the dry intrusion is not appropriate for cyclogenesis in the Mediterranean, and, in some cases, a weaker PV streamer associated with a less pronounced descent is sufficient for cyclogenesis. In this regard, Ianos, one of the strongest medicanes ever recorded, presents two weak descending flows associated with PV streamers, one in the early stage and one before the strong deep warm core phase. This cyclone has also been analyzed through a simulation with the WRF model with a grid spacing of 3 km, with the main aim of evaluating the different terms of the pressure tendency equation (PTE), to quantify the role of upper-level dynamics and diabatic heating on the surface pressure tendency. The same procedure has been applied to analyze the recent cyclone Daniel that affected Libya in September 2023, and a comparison with Ianos has been performed.

The landscape, as a comprehensive entity encompassing diverse ecosystems, cultural values, aesthetic qualities, and geological features, is integral to the concept of natural heritage. Climate change poses a substantial threat to landscapes. The impacts are multifaceted, affecting not only the ecological integrity of these areas but also their cultural significance and the livelihoods of people who depend on them. Efforts to mitigate climate change and adapt to its effects are crucial to preserving valuable landscapes for future generations.TOPIO project aims to contribute to addressing these issues by developing a holistic methodology where Citizen Science, Policy Outreach, Artificial Intelligence and Public Participatory GIS approaches, with the aid of Earth Observation, Digital Twins and Geoinformatics, will find common ground in order to involve both scientists and citizens in a “bottom-up” participatory and creative initiative for the implementation of the European Landscape Convention (ELC) in different areas of Europe. In this framework, TOPIO will prepare a landscape guide inspired by the ELC, initially focused on seven study areas across Europe. The identified topics will address urgent issues impacting the evolution of landscapes, focusing, among others, on climate change mitigation and adaptation.A Landscape Character Assessment (LCA) covering the study areas will also be conducted based on public participation. The aim is to increase citizen awareness of landscape policies and involve society in safeguarding landscape heritage from the impacts of climate change. Furthermore, the LCA can serve as a tool for local and regional authorities to assess and manage climate-related risks.

Since fifteen years, there have been many publications on flood-related mortality, especially in Europe. However, the countries on the southern side of the Mediterranean sea (northern Africa) have received little attention. This presentation introduce the results of a study on flood-related mortality in Morocco and Tunisia. The period covered is 1980-2020, to ensure consistency with European publications. The method used starts from research in the newpapers, internet, existing database such as EM-DAT and in scientific and technical bibliography. Identified flood related fatalities are then confirmed on field, especially to obtain the location and the accurate circumstances of of the deaths.
1,400 deaths in Morocco and 275 in Tunisia have been identified between 1980 and 2020, but the number of deaths is probably underestimated before 1995 in Morocco and before 2010 in Tunisia. Indeed, data quality varies considerably from one period to the next. In Morocco, the Ourika flood event that triggered between 200 to 700 fatalities in August 1995 raised awareness of the issue of flooding. Since then, data collection has become much more accurate. In Tunisia, it was the spread of the Internet and the 2011 revolution that enabled flood information to be disseminated, particularly in the newspapers. The mortality rate for each country's population ranges from 0.66 (Tunisia) to 1.2 (Morocco) death per year and per million inhabitants.
The first result is the predominance of outdoor fatalities, either by car or pedestrians, for example when crossing wadis. Deaths at home are rarer than in Europe. We must note in Morocco the specific case of old houses that collapse during heavy rainstorms events. The age of dead people is younger than in Europe, reflecting the youth of the North African population. Men are over-represented. The geographical distribution of deaths shows mortality hotspots linked to population distribution. In Tunisia, fatalities have concentrated over the last ten years in the Tunis city region and along the coast, reflecting the increase in population along the coast.

Extreme precipitation events pose significant challenges, especially in semi-arid regions where climate change has increased the frequency of such episodes, exacerbating the lack of adequate infrastructure to mitigate their impacts. The integration of satellite data with modeling techniques emerges as a crucial strategy for characterizing and predicting these events effectively. The Spain’s floods in September 2019 serve as a poignant example, resultingin in 7 casualties and 19 million euro in damages. The more affected regions were the Valencian Community, the Region of Murcia, Castilla-La Mancha and Andalusia, with areas in the south of the Community of Madrid also experiencing significant impacts by the end of the episode.
An analysis comparing satellite data with outputs from Numerical Weather Prediction (NWP) and simple hydrological models, alongside direct observations such as METEOSAT data, rain gauges and ground Doppler radars, reinforces the critical role of satellites in managing hydrometeorological events effectively. The Global Precipitation Measurement (GPM) Core Observatory, operational since 2014, and merged satellite estimates have demonstrated remarkable improvements over previous technologies. Additionally, the timely availability of satellite estimates enables near-real-time monitoring of severe hydrometeorological episodes.
While future automation of models remains a goal, current reliance on satellite products such as Integrated Multi-satellitE Retrievals (IMERG) can significantly aid in addressing societal needs. The ultimate objective is to transition from observation-based responses to predictive capabilities, with satellite data playing a central role in this transformation.

Lightning can influence many human activities, being a threat also for human lives. The Mediterranean area is prone to thunderstorms and lightning. In this context, lightning forecast plays a fundamental role. We studied the impact of lightning data assimilation (LDA) on lightning and precipitation forecast over Italy and over part of the Central Mediterranean Basin. First, we highlight some characteristics of strokes over Italy and the Central Mediterranean [1], considering data over 13 years recorded by LINET (LIghtning NETwork). The analyses of the records show that lightning activity occurs mainly in summer and fall; moreover, a substantial change of convection characteristics between the two season is apparent. In summer, convection occurs over the land, in fall it is mainly over the sea.Then, we consider a two-seasons data assimilation experiment [2] running the Weather Research and Forecasting (WRF) model coupled with the Dynamic Lightning Scheme (DLS) at 3km horizontal resolution for summer 2020 and fall 2021. Each simulation produced the forecast for the following 6h. Therefore, the representation of a whole day needs four different simulations. Verification is done over two sub-periods, 0-3h and 3-6h after assimilation. Results for the 0-3h phase show a positive impact of LDA on strokes forecast, both improving correct forecasts and reducing false alarms. Depending on the case, LDA can trigger convection missed by control forecast and can correct strokes’ patterns, leading to predictions more in agreement with observations. An improvement compared to the previous day forecast, without LDA, is also obtained. Therefore, the forecast over the 0-3h phase with LDA is applicable to issue warnings and alerts as the storm is approaching. LDA forces convection where lightning is observed. Consequently, lightning forecast improvement given by LDA, is more evident over the land in summer and over the sea in fall. The 3-6h phase show a negligible impact of LDA on strokes forecast.References[1] Marco Petracca, Stefano Federico, Nicoletta Roberto, Silvia Puca, Leo Pio D'Adderio, Rosa Claudia Torcasio, Stefano Dietrich.

Dust storms represent a significant source of aerosols in the atmosphere, impacting atmospheric composition and air quality. Moreover, the pollution caused by dust storms can exert a radiative effect, influencing short-term weather patterns and climate. In our research, we employed the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) to investigate how dust storms affect aerosol pollution levels and their related short-term meteorological consequences, using the Eastern Mediterranean as a case study. We focused on the severe dust outbreak of March 2018, a period marked by intense dust transport in the Easten Mediterranean and especially Greece caused mainly by strong southwesterly winds. We conducted model experiments, comparing scenarios with and without dust emissions to quantify the influence of these emissions on dust concentration, aerosol optical depth (AOD), shortwave radiation, and meteorological variables such as temperature, water vapor and cloud cover. Our results indicate that high concentrations of dust in the atmosphere can reduce the amount of radiation reaching the surface due to scattering and absorption by the dust particles. Additionally, it was found that the reemitted longwave radiation can increase the temperature near the surface. Regions in central Greece, as well as Crete and western Turkey, show an increase in temperature when dust emissions are considered in simulations, since they were more affected by the dust. Finally, a decrease in water vapor concentration was noted, primarily attributed to the hygroscopic nature of the dust particles and also to the change in atmospheric circulation induced by increased temperatures. Our research underscores that aerosols generated by dust storms can significantly alter weather conditions, emphasizing the importance of incorporating such feedbacks for more accurate weather forecasting.
