How atmospheric CO2 can inform us on annual and decadal shifts in the biospheric carbon uptake period
Authors: Kariyathan Theertha , Bastos Ana , Reichstein Markus , Peters Wouter , Marshall Julia
Published: July 2024

Abstract. The carbon uptake period (CUP) refers to the time of each year during which the rate of photosynthetic uptake surpasses that of respiration in the terrestrial biosphere, resulting in a net absorption of CO2 from the atmosphere to the land. Since climate drivers influence both photosynthesis and respiration, the CUP offers valuable insights into how the terrestrial biosphere responds to climate variations and affects the carbon budget. Several studies have assessed large-scale changes in CUP based on seasonal metrics from CO2 mole fraction measurements. However, an in-depth understanding of the sensitivity of the CUP as derived from the CO2 mole fraction data (CUPMR) to actual changes in the CUP of the net ecosystem exchange (CUPNEE) is missing. In this study, we specifically assess the impact of (i) atmospheric transport (ii) inter-annual variability in CUPNEE (iii) regional contribution to the signals that integrate at different background sites where CO2 dry air mole fraction measurements are made. We conducted idealized simulations where we imposed known changes (∆) to the CUPNEE in the Northern Hemisphere to test the effect of the aforementioned factors in CUPMR metrics at ten Northern Hemisphere sites. Our analysis indicates a significant damping of changes in the simulated ∆CUPMR due to the integration of signals with varying CUPNEE timing across regions. CUPMR at well-studied sites such as Mauna Loa, Barrow, and Alert showed only 50 % of the applied ∆CUPNEE under non interannually-varying atmospheric transport conditions. Further, our synthetic analyses conclude that interannual variability (IAV) in atmospheric transport accounts for a significant part of the changes in the observed signals. However, even after separating the contribution of transport IAV, the estimates of surface changes in CUP by previous studies are not likely to provide an accurate magnitude of the actual changes occurring over the surface. The observed signal experiences significant damping as the atmosphere averages out non-synchronous signals from various regions.

Published: July 2024

Abstract. Two decades of ACE-FTS version 5.2 (v5.2) ozone data (2004–2023) are evaluated with ozonesonde data from across the globe. The biases between the ACE-FTS and ozonesonde measurements are first estimated by analysing coincident data pairs. A second approach is taken for the validation by comparing the ACE-FTS and ozonesonde monthly mean time series, with the former generated by sampling the ACE-FTS data within latitude/longitude boxes (i.e., ±5°/±30°) surrounding the stations and calculating the monthly averages. The biases, correlations, variation patterns and the mean states of the two time series are compared. The biases estimated in this way exhibit more consistent and smoother features than using the coincident pair method. The ACE-FTS and ozonesonde monthly mean time series are highly correlated and exhibit similar variation patterns in the lower stratosphere at all latitudes. The ACE-FTS instrument drifts for each station are assessed in terms of the long-term linear trends relative to ozonesondes, which, although highly stable, may have their own minor changes with time. The ACE-FTS ozone profiles exhibit in general high biases in the stratosphere, increasing with altitude up to ~10 % at around 30 km, and have local maximum differences with ozonesonde profiles at the tropopause heights. The ACE-FTS instrument drifts are generally insignificant overall in the stratosphere with high variation between the stations. Averaging the individual station instrument drifts within several latitude bands results in small insignificant drifts of within ±1 % dec-1 in the northern mid- to high latitudes, and the southern high latitudes, and a small positive insignificant drift of 0–3 % dec-1 in the tropics and southern mid-latitudes with overall uncertainties at 2–3 % dec-1 (2σ level) in the low stratosphere. In the troposphere, the average ACE-FTS instrument drifts vary with altitude and exhibit large drifts between -10 and +10 % dec-1 with uncertainties of 10 % dec-1.
Main regional climate modelling development at AEMET using HCLIM
Authors: Prieto Rico Ignacio , Sánchez Perrino Juan Carlos , Rodríguez Guisado Esteban
Published: July 2024

Several studies have shown the added value of convection-permitting climate modelling, in particular regarding extreme events, including heat waves and high precipitation events (Lind et al., 2020, Fosser et al., 2024). HCLIM consortium develops a high resolution climate model, with a non-hydrostatic version using AROME physics. Current evaluation has shown that HCLIM is a robust tool able to add value when reproducing the behaviour of the climate system over complex areas (Belusic et al., 2020).AEMET has been a member of HCLIM since its foundation and has participated in the effort to develop the model and provide a complete and adaptable tool. In particular, we present some results on the contributions from AEMET: as many basin resources depend significantly on groundwater, works focused on improving the surface component with a new watertable parametrization. On the other hand, AEMET has contributed actively to the development of a more detailed aerosol scheme. An active line of development is currently underway, focused on the development of a fully ocean-coupled model.Future plans include the generation of high resolution climate simulations over Spain, assessing the added value of the model and exploring different strategies for the generation of high resolution climate scenarios feeding National Adaptation Plan. Some preliminary results, evaluating the added value against CORDEX simulations, are shown. Additionally, several tests comparing different strategies regarding model configuration and the impact of the domain size and nesting strategy have been conducted, giving insight into designing the strategy for the generation of an ensemble of simulations.References:Belušić, Danijel & de Vries, Hylke & Dobler, A. & Landgren, Oskar & Lind, Petter & Lindstedt, David & Pedersen, Rasmus & Sánchez-Perrino, Juan & Médus, Erika & Ulft, Bert & Wang, Fuxing & Andrae, Ulf & Batrak, Yurii & Kjellström, Erik & Lenderink, Geert & Nikulin, Grigory & Pietikäinen, Joni-Pekka & Rodriguez-Camino, Ernesto & Samuelsson, Patrick & Wu, Minchao.

Link between the atmospheric thermal condition over the Tibetan-Iranian Plateaus and Eurasian–African climate through the Asian westerly jet stream
Authors: Nan Sulan , Liu Ge , Bao Yan , Chen Dan
Published: July 2024

The Tibetan-Iranian Plateaus (TIPs) located in the middle and low latitudes in Asia, distributed with many high mountains. They have important influences on their “downstream” atmospheric circulation and associated climate in South Asia, East Asia and North America through large-scale teleconnections and planetary/Rossby waves. The impacts of the TIPs on its “upstream” climate in the North Atlantic, Africa, Europe and West Asia have been reported in recent years. Using monthly mean data from the European Centre for Medium-Range Weather Forecasts interim reanalysis dataset and precipitation data from the Global Precipitation Climatology Project, we investigate the connections among the atmospheric thermal condition over the Tibetan-Iranian Plateaus (TIPs), the intensity of the Asian westerly jet stream (AWJS), and climate over the Eurasian–African region during boreal summer. At the entrance of the AWJS, the tropospheric air temperature over the TIPs (TTIP) has a significant negative correlation with precipitation and a positive correlation with surface air temperature (SAT) over West Asia, eastern Europe, and western Russia. Furthermore, the TTIP has a significant positive correlation with precipitation over Northeast Africa. At the exit of the AWJS, the TTIP has a significant negative correlation with precipitation and a positive correlation with SAT over East Asia. The TTIP has a significant positive correlation with precipitation over Northeast Asia. This distribution of TTIP-related precipitation and SAT over the Eurasian–African region can be explained by the four-quadrant conceptual model of a straight jet streak. The enhanced temperature gradient from the mid–lower to higher latitudes over the Asian continent, associated with a high TTIP, results in the enhancement of the AWJS. Two anomalous opposite meridional circulations appear at the entrance and exit of the AWJS, respectively, and are responsible for the distribution of the TTIP-related precipitation and SAT over the Eurasian–African region.
Specific humidity verification skill of ECMWF weather forecast model in the region of Vietnam
Authors: Perez Iago , Sparrow Sarah
Published: July 2024

In the context of an accelerated warming climate, outbreak episodes of certain diseases such as dengue are expected to increase in the future, thus increasing health burden in areas such as Vietnam. Because meteorological variables exert a great influence on dengue transmission, having accurate weather forecast data is key to predict future dengue outbreaks and mitigate future damages. Previous studies assessed the skill of ECMWF ensemble model on precipitation and temperature over Vietnam, but they did not include specific humidity, which also plays an important role in vector-borne disease transmission. Hence, the goal of this study is to assess the skill of ECMWF ensemble model at predicting specific humidity in the area of Vietnam, focusing on the regions of North and South Vietnam (particularly the area nearby Hanoi city and Ho Chi Minh City or HCMC). We used ERA5 reanalysis between the dates 2001-2020 for the evaluation. ECMWF data was preprocessed using a bias correction technique (quantile mapping) using ERA5 as reference to correct possible biases. Early results showed that ECMWF model predictions show a little bias (around 0.5 g/kg) and that it is usually skilful up to 10 days in advance, specially during dry season. Nonetheless, there is a considerable decrease in skill during the rainy season (from May to October), which is the period when Dengue activity is higher. These results will provide more insight about the ECMWF skill in the medium-range forecast and it will be useful to stablish Dengue-modelling warning systems and reduce future damages caused by this disease.

Published: July 2024

In May-June 2024, an intercomparison campaign is scheduled to take place in Valladolid, Spain, comparing different photometer models. Specifically, the campaign will involve the PREDE POM-02L from the Institute of Polar Sciences (CNR-ISP), the CIMEL CE318-T from the Atmospheric Optics Group (GOA) at Valladolid University, and the PFR from the Physikalisch-Meteorologisches Observatorium Davos (PMOD). The primary objective of this campaign is to assess the effectiveness of a personalized algorithm for determining Aerosol Optical Depth (AOD) and Angstrom Exponent (α), while also evaluating the quality of these measurements by comparing them with data from the AERONET station operated by the GOA. AOD measurements will be conducted at various wavelengths: 440, 500, 675, and 870 nm for CIMEL; 400, 500, 675, and 870 nm for PREDE; and 440, 500, and 870 nm for PFR; α will be evaluated between 500 and 870 nm for all the photometers. For the multi-instrument intercomparison, the recommendations defined in 2005 by the WMO during the event ’WMO/GAW expert workshop on a global surface network for long-term observations of columnar aerosol optical properties' will be followed. These consist of: (i) acquiring more than 1000 points over at least 5 days of measurements, with AOD500 between 0.04 and 0.20; (ii) ensuring traceability with 95% uncertainty within 0.005 + 0.01/m; (iii) using the 500±3 nm and 865±5 nm channels, with a bandwidth of 15 nm or less, since these channels are mostly free from absorption effects. Valladolid, a medium-size city in the northern Castilian plateau, typically experiences continental aerosols as the predominant aerosol type. AOD values tend to be lowest during winter, gradually increasing to peak levels in late spring and summer. Maximum AOD values in Valladolid are often associated with the presence of dust particles from Saharan dust outbreaks, which are characterized by low α values. This intercomparison campaign, spanning late spring and early summer, provides an opportunity to observe the first significant desert dust transport events at the site. Additionally, biomass-burning events, associated with high AOD and high α values, may also be observed during this period. Detecting and studying these events will be another key focus of the campaign. In conclusion, this campaign offers us a chance to assess how well different sun-photometers work. Additionally, we’ll be able to study how desert dust and biomass burning events affect the site during this period.

 
A preliminary assessment of economic damages caused by weather hazards in the city of Santander (Northern Spain)

Published: July 2024

The Iberian Peninsula is widely considered as one of the main hot-spots of climate change. However, the type and magnitude of the impacts to which the different regions of the Iberian Peninsula are exposed are quite different. To improve the knowledge of the future vulnerability of the Cantabrian coast, this contribution identifies the weather hazards which produced quantifiable damages in the city of Santander between 1996 and 2023, characterizes them according to the atmospheric circulation patterns, and studies their temporal evolution over the last decades.Several databases have been combined to carry out this contribution. On the one hand, information on economic claims for extraordinary damages recorded by the Consorcio de Seguros, under the categories of flooding (“inundaciones extraordinarias”), windstorms (“tempestades ciclónicas atípicas”) and wavestorms “Embates de Mar”). In addition, that information is disaggregated spatially, which allows a better approximation of the spatial vulnerability. In relation to the meteorological data, the observed values of different meteorological variables at Santander Airport were collected, as well as the sea level values from two existing tide gauges. This information has been supplemented by analogous records from the ERA5 database, available from COPERNICUS (https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels?tab=overview). Finally, a synoptic catalogue (elaborated following the Jenkinson and Collison procedure) and a cyclone track database (Northern Hemisphere Extratropical Cyclone Tracks; https://canwin-datahub.ad.umanitoba.ca/data/dataset/nsidc-extratropical-cyclone-tracking-cnect), were also used to characterize the large-scale circulation patterns.Throughout the study period, the city suffered weather events that produced damage of different amounts and spatial location. Flooding is responsible for the large number of claims, caused by episodes of heavy rainfall. These can occur at any time of the year; however, while winter events tend to be of moderate hourly intensity and prolonged in time, due to extratropical disturbances, summer events tend to cause very high intensities in short periods of time, as corresponds to convective events triggered by upper throughs and high sea temperatures. In some cases, a high sea level also contributes to flooding by blocking the flow of the rain to the sea. Windstorms are also a common phenomenon in Santander. They correspond to storms with two trajectories (W-NW and S), the first being responsible for the most damaging episodes. Finally, coastal storms produce a relatively small number of economic damages, due to the low exposition of the city to these phenomena. They are generated by a swell caused by storms usually far from the Iberian Peninsula in combination with spring tides.

Published: July 2024

Recently, changes in the intensity and frequency of tropical cyclones related to Warming Climate have been observed, although uncertainties persist regarding this matter. Tropical cyclones, which are among the most dangerous weather phenomena, can arise from different conditions. However, those affecting Western Europe predominantly originate from a tropical transition and occur during the Autumn season. Consequently, this study aims to examine differences in the climatology of the variables related to tropical cyclogenesis during different periods from 1980 to 2100 in the North Atlantic basin under the influence of Warming Climate. The periods considered are: historical (1981 - 2010), near future (2021 – 2050) and far future (2071 – 2100), since periods with a statistically significant length, which represent the historical climate and two future climates spaced in time are needed. For this purpose, the SSP5-8.5 scenario from the EC-Earth3 climate model is used.
The results indicate significant rises in Sea Surface Temperature, Total Column Water and Geopotential Height at 300 hPa, alongside significant anomalies in the tropospheric Averaged Potential Vorticity, especially for the last part of the XX1 century. These changes lead to a percentile Vertical Wind Shear and air column stability reduction in almost the whole domain for the last part of the current century. Overall, these outcomes suggest an increased susceptibility to tropical cyclones formation in the North Atlantic basin due to Warming Climate, raising concerns about the potential for significant material damage and loss of human life caused by these systems. This study is a first approximation on how these high-impact severe weather events can evolve in the future, allowing for a better understanding of how tropical cyclogenesis could change with global warming.

Published: July 2024

Climate change has intensified the severity and frequency of natural disasters, with rising global temperatures exacerbating droughts and intensifying rainfall, resulting in devastating flood events. The Municipality of Zagori, located in the Epirus region, Greece, experiences recurrent flash floods, particularly during the autumn and early winter months. To address this challenge, the SMILE project, funded by the Greek Government, aims to develop a localized forecasting system tailored to the specific needs of the Zagori Municipality, integrating machine learning techniques with traditional hydrological models.
This project proposes a comprehensive tool equipped with a monitoring system designed to provide real-time data on hydrometric and meteorological parameters. Leveraging machine learning algorithms, such as neural networks and ensemble methods, alongside traditional statistical and physical models, the SMILE system enhances the accuracy and reliability of weather and flood predictions for the Municipality of Zagori.
The SMILE system offers a user-friendly online platform, allowing stakeholders to access and process data from connected sensors, including hydrometric stations along torrents and meteorological stations across the watershed. Advanced feature engineering techniques are employed to extract meaningful information from large and diverse datasets, facilitating the development of robust prediction models.
Moreover, the system incorporates sensors connected to dataloggers with internal 4G modems, enabling real-time monitoring and interoperability with a 1D/2D hydraulic model. This hydraulic model, enhanced by machine learning insights, focuses on critical areas prone to flash floods, aiming to issue timely warnings and mitigate potential risks more effectively.
By integrating machine learning techniques with traditional hydrological models, the SMILE project seeks to enhance early warning capabilities and improve disaster preparedness in the Municipality of Zagori. The development of this localized forecasting system represents a proactive approach to address the impacts of climate change and mitigate the adverse effects of extreme weather events in vulnerable regions.
Flash drought characteristics based on three identification methods in the North China Plain, China
Authors: Zhang Siyao , Li Jianzhu , Zhang Ting , Feng Ping
Published: July 2024

Abstract. Flash drought (FD) is an onset and intensify rapidly type of drought that can harm the terrestrial ecosystem, and cause economic and agricultural losses. The North China Plain (NCP) is an important agricultural region in China where sustainable development is restricted by the frequent droughts and insufficient water resources. Coping with FD requires an understanding of the FD onset and identification in the NCP. Based on root zone soil moisture (RZSM), standardized evaporative stress ratio (SESR) and multiples of mean evaporative stress ratio (MESR), this study identified the FD events in the NCP from 1981 to 2022, revealed the FD characteristics such as frequency, duration, severity and intensity, explored the temporal and spatial trend, determined the FD hotspots, and demonstrated the impact of FD identification thresholds on the FD identification. The frequency distributions of FD events identified by RZSM, SESR, and MESR are all high in the central and northern NCP and low in the southern, whereas the total duration is high in the southern and eastern NCP and low in the northern. As the FD intensity increases, the onset stage lengthens, the recovery stage shortens, the total duration reduces, and the severity declines. The FD affected areas from various FD identification methods exhibit significant and similar seasonal variations, primarily occurring from May to August. Besides, NCP is prone to extreme and exceptional FDs. The NCP has a decreasing tendency of the FD characteristics, and three hotspots with frequent and serious FD events are identified in the northwestern, eastern and southwestern NCP. The FD frequency is also significantly influenced by the thresholds in the identification methods. This study provides insights into the FD characteristics in the NCP, and clarifies its trend and hotspots, which may be valuable for FD understanding and adaptation.
High capacity of integrated crop–pasture systems to preserve old soil carbon evaluated in a 60-year-old experiment
Authors: González-Sosa Maximiliano , Sierra Carlos A. , Quincke J. Andrés , Baethgen Walter E. , Trumbore Susan , Pravia M. Virginia
Published: July 2024

Abstract. Integrated crop–pasture rotational systems can store larger soil organic carbon (SOC) stocks in the topsoil (0–20 cm) than continuous grain cropping. The aim of this study was to identify if the main determinant for this difference may be the avoidance of old C losses in integrated systems or the higher rate of new C incorporation associated with higher C input rates. We analyzed the temporal changes of 0–20 cm SOC stocks in two agricultural treatments of different intensity (continuous annual grain cropping and crop–pasture rotational system) in a 60-year experiment in Colonia, Uruguay. We incorporated this information into a process of building and parameterizing SOC compartmental dynamical models, including data from SOC physical fractionation (particulate organic matter, POM > 53 µm > mineral-associated organic matter, MAOM), radiocarbon in bulk soil, and CO2 incubation efflux. This modeling process provided information about C outflow rates from pools of different stability, C stabilization dynamics, and the age distribution and transit times of C. The differences between the two agricultural systems were mainly determined by the dynamics of the slow-cycling pool (∼MAOM). The outflow rate from this compartment was between 3.68 and 5.19 times higher in continuous cropping than in the integrated system, varying according to the historical period of the experiment considered. The avoidance of old C losses in the integrated crop–pasture rotational system resulted in a mean age of the slow-cycling pool (∼MAOM) of over 600 years, with only 8.8 % of the C in this compartment incorporated during the experiment period (after 1963) and more than 85 % older than 100 years old in this agricultural system. Moreover, half of the C inputs to both agricultural systems leave the soil in approximately 1 year due to high decomposition rates of the fast-cycling pool (∼POM). Our results show that the high capacity to preserve old C of integrated crop–pasture systems is the key for SOC preservation of this sustainable intensification strategy, while their high capacity to incorporate new C into the soil may play a second role. Maintaining high rates of C inputs and relatively high stocks of labile C appear to be a prerequisite for maintaining low outflow rates of the MAOM pool.

Published: July 2024

The mass-charge spectra of multiply charged ions in a two-element laser plasma are studied bylaser ionization mass-spectrometry. The package of the mass spectrum of the Eu2O3 ions of thelaser plasma was obtained within the limits of the potential of the electrostatic analyzer U=3−50 V and the power density q=1011 W/cm2. It was revealed that O1+, O2+ ions are clearly observedin the mass spectra at low values (U=3−20 V) of the electrostatic analyzer potential,and Eu1+, Eu2+, Eu3+ ions at relatively high values (U=15−50 V) of the electrostatic analyzerpotential. It has been experimentally shown that the properties of both light and heavy ions inplasma depend on the conditions for the entry of gas atoms into the target and on secondaryprocesses occurring after the formation of a dense plasma near the sample surface.

Authors: Absanov A.
Published: July 2024

In this work, interactions in biologically active active “butanoid (butyric) acid (BA)-acetonitrile/DMSO/pyridine/water” complexes and their spectral manifestations were studiedusing ab-ibitio calculations. When complex formation energies are calculated, this energyincreases as the number of molecules increases, but the average hydrogen bond energy correspondingto each bond does not change. Mulliken charge distributions were also analyzedthrough the optimal geometry of the molecules. Calculations showed that during the formationof complexes, the acid is formed through the atoms of the O-H and C=O, and the charge distributionin the atoms of this grouphas changed, and C=O…H, O-H…O (N) and C-H…O formationof complexes was occurred through hydrogen bonds. Also, for acids in complexesformed by DMSO/pyridine/water, the vibration bands (OH and C=O stretching vibrations) areshifted to lower frequencies, and this shift is greater for the OH vibration band than for theC=O stretching vibrations group.

Published: July 2024

Myasthenia Gravis (MG) is a neuromuscular junction disorder characterised by antibodies directed against postsynaptic antigens (mainly the Acetylcholine Receptors (AChR)). The management of MG symptoms relies on the utilization of anticholinesterases (such as Pyridostigmine), immunosuppressive and immunomodulatory therapies, including therapeutic plasmapheresis or high-dose human immunoglobulin. The removal of thymoma presents an oncological “urgency», in the context of myasthenic patients, it is crucial to undertake the operation solely when myasthenic symptoms are effectively controlled by pharmacological therapy. A literature review was conducted on Pubmed with the terms “thymoma” and “steroid” to explore the role of steroids, administrated for MG treatment in tumor dimension reduction. To date, only a limited number of studies have investigated the effect of steroids on tumour size, particularly in the context of thymoma, which is relatively rare. Finally we presented the case of a 53-year-old male patient affected of a severe form of MG and a thymoma with suspicious infiltration of anonymous vein, who was treated with high doses of steroids, with final control on MG symptoms and tumor dimension reduction. The patients was at the end operated successfully with a robot assisted technique.

Introduction: Capecitabine is a chemotherapeutic widely used in current medical practice, quickly replacing 5-Fluorouracil in the treatment of certain cancers. Although it is rarely encountered, neurotoxicity is an adverse effect that should not be neglected, especially if elderly patients are involved. Case: An 82-year-old patient, diagnosed with digestive neoplasm, currently being treated with Capecitabine, is brought to the emergency room by her family for an acute confusional episode and speech disorder. Brain imaging is performed, which does not identify significant lesions, and biological tests exclude major imbalances that would explain the neurological dysfunction. Stopping the chemotherapy treatment determines the rapid resolution of the symptoms. Thus, the diagnosis of toxic encephalopathy is made and it is decided to definitively stop treatment with Capecitabine. Conclusion: These being presented, whenever there is an alteration of the neurological status during treatment with Capecitabine, Reversible toxic encephalopathy should be considered. This drug remains a preferred chemotherapy in current practice, but the adverse neurological effects should not be neglected, especially for the population at risk.
