Abstract. The effect of mineral dust emitted from arid and semiarid surfaces upon climate and ecosystems depends fundamentally on their particle size distribution (PSD) and size-resolved mineralogical composition. However, soil mineralogy atlases used for mineral-speciated dust modelling are highly uncertain as they are derived extrapolating mineralogical analyses of soil samples that are particularly scarce in dust-source regions. This extrapolation neglects the processes affecting the formation of different dust-emitting surface sediments, such as dunes, crusts, and paved sediments. The Lower Drâa Valley, an inland drainage basin and preferential dust-source located in southern Morocco, was chosen for a comprehensive analysis of sediment grain size and mineralogy. Different sediment types samples were collected, including paleo-sediments, paved surfaces, crusts, and dunes, and analysed through PSD analysis of minimally and fully dispersed samples, and X-ray diffraction mineralogical analysis of bulk samples. We also performed Fe sequential wet extraction to characterize Fe mineralogy, including the contents of (oxyhydr)oxides (goethite and hematite), key to dust radiative effects, and poorly crystalline pool of Fe (readily exchangeable ionic Fe and nano-Fe-oxides), relevant to dust impacts upon ocean biogeochemistry. Based on the results we propose a conceptual model where both particle size and mineralogy are segregated by transport and deposition of sediments during runoff of water across the basin, and by the precipitation of salts, which causes a sedimentary fractionation. Coarser particles substantially richer in quartz are more present in elevated areas, and finer particles rich in clay, carbonates, and Fe-oxides are present in depressed areas, where dust emission is maximized. When water ponds and evaporates, secondary carbonates and salts precipitate, and the clays are enriched in readily exchangeable ionic Fe, due to sorption of dissolved Fe by illite. Our results differ from currently available mineralogical atlases and highlight the need for observationally-constrained global high-resolution mineralogical data for mineral-speciated dust modeling.

Abstract. Wildfires are an important source of carbonaceous aerosol in the atmosphere. Organic aerosol that absorbs light in the ultraviolet to visible spectral range is referred to as “brown carbon” (BrC), and its impact on Earth’s radiative budget has not been well characterized. We collected water-soluble brown carbon using a particle into liquid sampler (PILS) onboard a Twin Otter aircraft during the Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) campaign. Samples were collected downwind of wildfires in the western United States from August to September 2019. We applied size exclusion chromatography (SEC) with ultraviolet-visible spectroscopy to characterize the molecular size distribution of BrC chromophores. The wildfire plumes had transport ages of 0 to 5 h and the absorption was dominated by chromophores with molecular weights <500 Da. With BrC normalized to a conserved biomass burning tracer, carbon monoxide, a consistent decrease in BrC absorption with plume age was not observed during FIREX-AQ. These findings are consistent with the variable trends in BrC absorption with plume age reported in recent studies. While BrC absorption trends were broadly consistent between the offline SEC analysis and the online PILS measurements, the absolute values of absorption and their spectral dependence differed. We attribute this difference to the organic modifier used in the chromatographic separation and demonstrate how this affects the molecular structure of the compounds comprising BrC, with implications for interpretation of absorption measurement of BrC field samples.
Quantifying Contribution of Atmospheric Circulation to Precipitation Variability and Changes in the U.S. Great Plains and Southwest Using Self Organizing Map – Analogue
Authors: Zhuang Yizhou , Fu Rong
Published: June 2023

Abstract. The Great Plains and Southwest regions of the U.S. are highly vulnerable to precipitation-related climate disasters such as droughts and floods. In this study, we propose a self-organizing map–analogue (SOMA) approach to empirically quantify the contribution of atmospheric circulation (mid-tropospheric geopotential and column moisture transport) to the regional precipitation anomalies, variability, and multi-decadal changes. Our results indicate that atmospheric circulation contributes significantly to short-term precipitation variability, accounting for 54–61 % of the total variance and 62–68 % of the amplitude of the mean precipitation anomalies in these regions, though these contributions vary significantly across seasons. The remaining variance is largely influenced by thermodynamically driven factors. As indicated in previous research, Pacific Decadal Oscillation (PDO) is one of the major climate modes influencing the long-term multi-decadal variation of precipitation. By contrasting three multi-decadal periods (1950–1976, 1977–1998, 1999–2021) with shifting PDO phases and linking the phase shift to circulation SOM nodes, we found that circulation changes contribute considerably to the multi-decadal changes of precipitation anomaly in terms of the mean and probability of dry and wet extremes, especially for the Southern GP and Southwest. However, these circulation-induced changes are not totally related to the PDO phase shift (mostly less than half), atmospheric internal variability or anthropogenically induced changes in circulation can also be potential contributors. Our approach improves upon flow analogue and SOM-based methods and provides insights into the contribution of atmospheric circulation to regional precipitation anomalies and variability.

Published: June 2023

Abstract. Light-absorbing organic species present in aerosols, collectively called brown carbon (BrC), contribute important but highly uncertain effects on climate. Clouds likely represent a significant medium for secondary BrC production and for bleaching reactions, though the relative importance of formation and loss processes in clouds is unknown at present. The acidity (or pH) of atmospheric particles and clouds affects the optical properties of BrC and bleaching rates. Given the wide variability of pH in the atmosphere (pH in particles and clouds ranges from -1 to 8), the optical properties of BrC and its bleaching behavior are expected to vary significantly, and the link between pH and BrC is yet another uncertainty in attempts to constrain its climate forcing effects. In this work, we characterize the pH-dependence of BrC optical properties – including light absorption at 365 nm (Abs365), mass absorption coefficient (MAC365), and the absorption Ångström exponent (AAE) – in bulk cloud water sampled from the summit of Whiteface Mountain, NY. In all samples (n = 17), Abs365 and MAC365 increased linearly with increasing pH, highlighting the importance of reporting pH in studies of BrC in aqueous media. There was strong variability in the sensitivity of Abs365 to pH, with normalized slopes that ranged from 5.1 % to 17.2 % per pH unit. The normalized slope decreased strongly with increasing cloud water [K+], suggesting that the non-biomass burning BrC has optical properties that are more sensitive to pH than BrC associated with biomass burning. AAE also showed a distinct pH-dependence, as it was relatively flat between pH 1.5 – 5, then decreased significantly above pH 5. The cloud water composition was used to inform thermodynamic predictions of aerosol pH upwind/downwind of Whiteface Mountain and the subsequent changes in BrC optical properties. Overall, these results show that, in addition to secondary BrC production, photobleaching, and the altitudinal distribution, the climate forcing of BrC is quite strongly affected by its pH-dependent absorption.

Abstract. Hailstorms, while fascinating from a meteorological perspective, pose significant risks to communities, agriculture, and infrastructure. In regions such as the Central Andes of Peru, the characteristics and frequency of these extreme weather events remain largely uncharted. This study fills this gap by investigating the historical frequency and vertical structure of hailstorms in this region. We analyzed historical hailstorm records dating back to 1958 alongside four years of observations (2017–2021) from Parsivel2 disdrometer and a cloud profiler radar MIRA35c. Our findings indicate a trend of decreasing hail frequency (-0.5 events/decade). However, the p-value of 0.07 suggests the need for further investigation, particularly in relation to environmental changes and reporting methods. The results show that hailstorms predominantly occur during the austral summer months, with peak frequency in December, and are most common during the afternoon and early evening hours. The analysis of radar variables such as reflectivity, radial velocity, spectral width, and linear depolarization ratio (LDR) reveals distinct vertical profiles for hail events. Two case studies highlight the diversity in the radar measurements of hailstorms, underscoring the complexity of accurate hail detection. This study suggests the necessity for refining the Parsivel2 algorithm and further understanding its classification of hydrometeors. Additionally, the limitations of conventional radar variables for hail detection are discussed, recommending the use of LDR and Doppler spectrum analysis for future research. Our findings lay the groundwork for the development of more efficient hail detection algorithms and improved understanding of hailstorms in the Central Andes of Peru.

Published: June 2023

Abstract. Between 2018 and 2022, four pearl farming Tuamotu atolls of French Polynesia were monitored with autonomous oceanographic instruments to measure the hydrodynamics of atoll lagoons and the ocean-lagoon water exchanges. These surveys were conducted in the frame of ANR MANA (Management of Atolls) project and its extensions to additional sites. The overarching goal was to improve knowledge on the processes influencing the spat collection of the pearl oyster Pinctada margaritifera, the oyster species used to produce black pearls. These data sets are also critical for the calibration and validation of 3D high spatial resolution hydrodynamic models used to study the oyster larval dispersal within lagoons. The observational strategies focused on the characterization of ocean/lagoon exchanges through passes and hoa (i.e., shallow reef flats), lagoon circulation, incident waves breaking on the forereef, water elevation inside lagoon as well as spatial temperature variability. Chronologically, the investigated atolls were first Raroia Atoll with 9 months measurements between May 2018 and March 2019 during which the MALIS1 and MALIS2 cruises on-board the R/V ALIS took place. It was followed by a 4-month deployment in Takapoto Atoll (November 2021 to March 2022). In late April 2022, Apataki Atoll was instrumented until end of July, followed by Takaroa measurements between July to October. Apataki (Leg2) and Takaroa Atoll were conjointly instrumented during the MALIS 3 oceanographic cruise. Altogether, those multi-atoll data bring a worldwide unique oceanographic atoll data set, useful to address local pearl farming questions but potentially beneficial for other fundamental and applied investigations. Each data set was post processed, quality controlled and converted in NetCDF format. Files are available in open source into dedicated repositories in the SEANOE marine data platform with permanent DOIs.

Published: June 2023

Abstract. High-quality spectral reference libraries are important for algorithm development and identification of diagnostic optical features of target objects in environmental remote sensing applications. We present additional measurements conducted using hyperspectral sensor technologies in a laboratory and outdoor setting to further extend high-quality data as well as diversity in available open-access spectral reference libraries. These observations involved gathering hyperspectral single-pixel point and multi-pixel optical properties of a diverse set of plastic materials (e.g., ropes, nets, packaging, and personal protective equipment). Measurements of COVID-19 personal protective equipment were conducted to also further expand reference datasets that could be useful in monitoring mismanaged waste related to the pandemic. The sample set consisted of virgin polymers and ocean-weathered and artificially biofouled objects of varying apparent colors, shapes, forms, thicknesses, and opacity. A Spectral Evolution spectroradiometer was used to collect hyperspectral reflectance single pixel point information from 280 – 2500 nm. Imaging was also performed using a Specim IQ hyperspectral camera from 400 – 1000 nm. Sampling underwater was completed in intervals of 0.005 m to 0.215 m within a 0.005 – 0.715 m depth range. All optical measurements are available in open-access for the laboratory experiment through https://doi.org/10.4121/769cc482-b104-4927-a94b-b16f6618c3b3 (de Vries and Garaba, 2023) and outdoors campaign involving the biofouling samples via https://doi.org/10.4121/7c53b72a-be97-478b-9288-ff9c850de64b (de Vries et al., 2023).
A gridded multi-site precipitation generator for complex terrain: an evaluation in the Austrian Alps

Published: June 2023

Abstract. For climate change impact assessment, many applications require very high-resolution, spatiotemporally consistent precipitation data on current or future climate. In this regard, stochastic weather generators are designed as a statistical downscaling tool that can provide such data. Here, we adopt the precipitation generator framework of Kleiber et al. (2012), which is based on latent and transformed Gaussian processes, and propose an extension of that framework for a mountainous region with complex topography by allowing elevation dependence in the model. The model is used to generate two-dimensional fields of precipitation with a 1 km spatial resolution and a daily temporal resolution in a small region with highly complex terrain in the Austrian Alps. This study aims to evaluate the model with respect to its ability to simulate realistic precipitation fields over the region using historical observations from a network of 29 meteorological stations as input. The model's added value over the original setup and its limitations are also discussed. The results show that the model generates realistic fields of precipitation with good spatial and temporal variability. The model is able to generate some of the difficult areal statistics useful for impact assessment, such as the areal dry and wet spells of different lengths and the areal monthly mean of precipitation, with great accuracy. The model also captures the inter-seasonal and intra-seasonal variability very well, while the inter-annual variability is well captured in summer but largely underestimated in autumn and winter. The proposed model adds substantial value over the original modeling framework, specifically with respect to the precipitation amount. The model is unable to reproduce the realistic spatiotemporal characteristics of precipitation in autumn. We conclude that, with further development, the model is a promising tool for downscaling precipitation in complex terrain for a wide range of applications in impact assessment studies.
Contribution of solitons to enhanced rogue wave occurrence in shallow depths: a case study in the southern North Sea
Authors: Teutsch Ina , Brühl Markus , Weisse Ralf , Wahls Sander
Published: June 2023

Abstract. The shallow waters off the coast of Norderney in the southern North Sea are characterised by a higher frequency of rogue wave occurrences than expected. Here, rogue waves refer to waves exceeding twice the significant wave height. The role of nonlinear processes in the generation of rogue waves at this location is currently unclear. Within the framework of the Korteweg–de Vries (KdV) equation, we investigated the discrete soliton spectra of measured time series at Norderney to determine differences between time series with and without rogue waves. For this purpose, we applied a nonlinear Fourier transform (NLFT) based on the Korteweg–de Vries equation with vanishing boundary conditions (vKdV-NLFT). At measurement
sites where the propagation of waves can be described by the KdV equation, the solitons in the discrete nonlinear vKdV-NLFT spectrum correspond to physical solitons. We do not know whether this is the case at the considered measurement site. In this paper, we use the nonlinear spectrum to classify rogue wave and non-rogue wave time series. More specifically, we investigate if the discrete nonlinear spectra of measured time series with visible rogue waves differ from those without rogue waves. Whether or not the discrete part of the nonlinear spectrum corresponds to solitons with respect to the conditions at the measurement site is not relevant in this case, as we are not concerned with how these spectra change during propagation. For each time series containing a rogue wave, we were able to identify at least one soliton in the nonlinear spectrum that contributed to the occurrence of the rogue wave in that time series. The amplitudes of these solitons were found to be smaller than the crest height of the corresponding rogue wave, and interaction with the continuous wave spectrum is needed to fully explain the observed rogue wave.
Time series with and without rogue waves showed different characteristic soliton spectra. In most of the spectra calculated from rogue wave time series, most of the solitons clustered around similar heights, but the largest soliton was outstanding, with an amplitude significantly larger than all other solitons. The presence of a clearly outstanding soliton in the spectrum was found to be an indicator pointing towards the enhanced probability of the occurrence of a rogue wave in the time series. Similarly, when the discrete spectrum appears as a cluster of solitons without the presence of a clearly outstanding soliton, the presence of a rogue wave in the observed time series is unlikely. These results suggest that soliton-like and nonlinear processes substantially contribute to the enhanced occurrence of rogue waves off Norderney.
Deep Clustering in Radar Subglacial Reflector Reveals New Subglacial Lakes

Published: June 2023

Abstract. Ice-penetrating radar (IPR) imaging is a valuable tool for observing the internal structure and bottom of ice sheets. Subglacial water bodies, also known as subglacial lakes, generally appear as distinct, bright, flat, and continuous reflections in IPR images. In this study, we collect and generate a dataset of one-dimensional reflector waveform features from IPR images of the Gamburtsev Subglacial Mountains region in the CReSIS database, to investigate these features. We apply a deep learning method to reconstruct the reflector features, and subsequently downsample the features to a low-dimensional vector representation. An unsupervised clustering method is then used to separate different types of reflector features, including a reflector type corresponding to subglacial water bodies. The derived clustering labels are used to detect features of subglacial water bodies in IPR images. Using this method, we compare the new detections with the known lakes inventory. The results indicate that this new method identified additional subglacial lakes that were not previously detected, and some previously known lakes are found to correspond to other reflector clusters. This method can offer automatic detections of subglacial lakes and provide new insight for subglacial studies.
Grand challenges in the digitalisation of wind energy

Abstract. The availability of large amounts of data is starting to impact how the
wind energy community works. From turbine design to plant layout,
construction, commissioning, and maintenance and operations, new
processes and business models are springing up. This is the process of
digitalisation, and it promises improved efficiency and greater insight,
ultimately leading to increased energy capture and significant savings
for wind plant operators, thus reducing the levelised cost of energy.
Digitalisation is also impacting research, where it is both easing and
speeding up collaboration, as well as making research results more
accessible. This is the basis for innovations that can be taken up by
end users. But digitalisation faces barriers. This paper uses a
literature survey and the results from an expert elicitation to identify
three common industry-wide barriers to the digitalisation of wind
energy. Comparison with other networked industries and past and ongoing
initiatives to foster digitalisation show that these barriers can only
be overcome by wide-reaching strategic efforts, and so we see these as
“grand challenges” in the digitalisation of wind energy. They are,
first, creating FAIR data frameworks; secondly, connecting people and data to foster innovation; and finally, enabling collaboration and competition between organisations. The grand challenges in the digitalisation of wind energy thus include a mix of technical, cultural, and business aspects that
will need collaboration between businesses, academia, and government to
solve. Working to mitigate them is the beginning of a dynamic process
that will position wind energy as an essential part of a global clean
energy future.
O processo de lexicalização de “fanfic”

Published: June 2023

Lexicalização consiste na “adoção de um determinado termo pelo léxico de uma língua, como uma formação usual, constitucionalizada” (BARRETO, 2012, p. 408) e pode estar vinculada a outros processos como a gramaticalização que se caracteriza pela passagem de um item mais lexical para uma forma mais gramatical (FORTUNATO, 2008). Assumindo estes pressupostos, o presente trabalho busca demonstrar como “fanfic”, uma abreviação da expressão inglesa fanfiction, vem sofrendo modificações ao ser incorporada ao repertório linguístico dos internautas brasileiros. Para fim de análise, extraímos textos da plataforma Twitter, por meio da mineração de dados utilizando a linguagem de programação Python. E com base na análise de 2536 tweets, constatamos que “fanfic” e “fic” estão passando por processos de lexicalização, semanticização e gramaticalização, sendo que sua incorporação é submetida às regras fonológicas e morfológicas do português brasileiro.
O suicídio em Ulysses de James Joyce
Authors: Amaral Lara Luiza Oliveira
Published: June 2023

No episódio “Sereias”, Leopold Bloom puxa um elástico enquanto luta contra os seus pensamentos. Não querer pensar em Molly o leva a pensar na morte. Quando a pergunta “Você não está feliz?” aparece, o elástico estoura. Representação de si, o protagonista do romance de James Joyce está em seu limite – mas é o elástico que estoura, não Bloom. Discutir a incomunicabilidade em Ulysses não é novidade, muito menos o paralelo homérico ou a influência do luto. Dessa forma, propomos adicionar o suicídio como tema afluente destas questões, um aspecto de (des)construção do protagonista e da narrativa. Até que ponto o luto pelo pai também não caminha ao lado da possibilidade suicida que se apresenta após a morte voluntária na família? Quantas vezes o tema passa pela cabeça inquieta do personagem durante este único dia? Pensar nas relações shakespearianas de pai e filho também não é relembrar que Hamlet questionou sua existência e Ofélia atirou-se no rio? Com base em tais questionamentos, discutimos diferentes propostas de leitura do tema no clássico joyceano. Para tanto, nos pautamos, principalmente, em pesquisadores/as da obra de James Joyce, como Ames (2009), Durão (2013), Galindo (2016), Bennett (2017), entre outros.

Konteks ini muncul sebagai implikasi dari pengembangan high order thinking skill matematis melalui strategi MHM yang perlu dioptimalkan dalam proses pembelajaran sebagaimana prinsip-prinsip pembelajaran pada kurikulum 2013. Prinsip-prinsip pembelajaran abad 21 juga menjadi dasar pijakan sebagai salah satu dasar pertimbangan dalam pembiasaan (conditioning) dan pengembangan kemampuan berpikir tingkat tinggi siswa. Melalui kebiasaan berpikir matematis akan membentuk dan menumbuhkan disposisi matematis yaitu keinginan, kesadaran, dan dedikasi yang kuat pada diri siswa untuk belajar matematika dan melaksanakan berbagai kegiatan matematika. Dalam artikel ini dapat di batasi ruang lingkup pembahasan yaitu tentang pengembangan pembelajaran abad 21 berbasis HOTS matematis melalui strategi MHM yang dapat dikembangkan pada siswa SMP disertai dengan rasionalisasi dan contoh pembelajarannya. Oleh karena itu, pembahasan terdiri dari: hakekat mathematical habits of mind, dan strategi MHM dalam pembelajaran abad 21 berbasis HOTS matematis.

Językoznawstwo kryminalistyczne w krajach anglojęzycznych
Authors: Grądziel Martyna
Published: June 2023

Lingwistyka kryminalistyczna jako dziedzina kryminalistyki funkcjonuje w praktyce już od kilkudziesięciu lat, jednak po dziś dzień wielu autorów określa ją jako nową. Szczególnie na gruncie polskim daje się zauważyć brak zainteresowania możliwościami, jakie daje analiza językowa, nie tylko w procesie typowania nieznanego autora tekstu (profilowanie językowe), ale także udowadniania winy, np. przez przypisanie autorstwa lub ustalenie intencji nadawcy komunikatu. W artykule skupiono się na funkcjonowaniu językoznawstwa kryminalistycznego w krajach anglojęzycznych z uwagi na fakt, iż to właśnie w tych krajach dziedzina ta rozwija się najszybciej. Przedstawiono pokrótce najważniejsze zakresy zastosowania analizy językowej w procesie sprawowania wymiaru sprawiedliwości oraz omówiono najczęściej stosowane w tej dziedzinie lingwistyczne metody badawcze, opatrując je praktycznymi przykładami wykorzystania poszczególnych rodzajów analiz.

Published: June 2023

The route to success in socio-political field is paved with enormous economic growth that fosters any attempt at social advancement or development. The desire for advancement adds complexity to the lives of ambitious individuals and makes it harder for them to overcome substantial economic difficulties. This paper examines the struggle of South Asian people towards socio-political development in Mohsin Hamid's How to Get Filthy Rich in Rising Asia. In this paper, the socio-political success of the characters, its associated issues, and their impact on the protagonist's life are analyzed considering Karl Marx's notion of social conflicts theory. The idea suggests that individuals and groups’ relationships are based on conflict rather than on agreement. They want wealth and power to further entrench themselves and mistreat others who are weaker than them. The novel portrays protagonist's life is targeted by economic-based social issues that limits his plans to get success in socio-political arena. He exerts great effort, yet contemporary societal mores stand in the way of his success. The findings reveal that various characters try their best to carve out a place for themselves in the world and advance their social-p0litical standing, but they are not accepted by the emerging metropolitan culture, and they end up brokenhearted after a failed relationship.
