Published: April 2024

Objective: Current literature on coronavirus disease 2019 (COVID-19) research presents gaps and opportunities to investigate the psychological experiences of healthcare workers (HCWs) serving in mass trauma situations. We aimed to measure perceived stress, burnout, and resilience in Kashmiri HCWs and explore the relationship of burnout with sociodemographic, work-related, and pandemic-related factors.
Design, setting, and participants: This was a cross-sectional descriptive study. Data were collected by circulating a web-based questionnaire among HCWs across primary, secondary, and tertiary healthcare levels in Kashmir, India. The questionnaire consisted of sections on personal, work-related, and pandemic-related variables as well as validated instruments to measure perceived stress, burnout, and resilience.
Results: A total of 514 valid responses were received. More than 80 percent of HCWs had moderate to high perceived stress. The prevalence of personal, work-related, and client-related burnouts was 68, 48.6, and 46 percent, respectively. Resilience was negatively correlated with stress and burnout. Younger (18-28 years), unmarried HCWs, especially junior residents and nurses, had higher burnout levels. Redeployment to deliver COVID-19 duties, unpredictability in work schedule, tested positive for COVID-19, and spending time in isolation/quarantine were also found to be significant risk factors for developing burnout.
Conclusions: Nearly half of the HCWs suffered from burnout, and more than half had moderate to high perceived stress. In addition to pre-existing risk factors of burnout, the pandemic seems to have introduced more occupational risk factors in this disaster-affected area. Lessons learnt from COVID-19 pandemic may help guide need-based intervention strategies designed for specific target population rather than a one size fits all approach.

Published: April 2024

Objectives: Distal transradial approach (dTRA) is a promising technique with a decreased risk of radial artery occlusion and puncture-related injuries. There has been no data which compare dTRA and proximal transradial approach (pTRA) in Turkish population group, so far. Thus, researchers aimed to compare the efficacy and safety of the dTRA versus the conventional pTRA in coronary procedures in this study.
Methods: Between September 2021 and June 2022, patients scheduled for transradial angiography at a tertiary cardiac center were enrolled in this study. Patients were randomly selected to undergo coronary imaging using either the distal dTRA or the conventional pTRA in equal numbers. A total of 79 patients were randomized to the proximal approach, and 77 patients were randomized to the dTRA. The primary endpoint was defined as procedural failure.
Results: The success rate of cannulation of the dTRA was significantly lower compared to proximal pTRA (pTRA [89.6%] and pTRA [79%] p=0.002). The rate of radial artery thrombotic complications was not different between groups (proxymal %10.6 vs. distal %5.8, p=0.288). The time of cannulation and total procedural time were longer in the dTRA group (20–40 min, median 25 min) compared to the proximal radial group (15–30 min, median 20 min) p = 0.005. However, this did not affect the total scope time duration 3.3 min. (1.6–6.4) versus 2.4 min (1.6–3.7).
Conclusion: dTRA has a relatively long access time with no advantages in terms of thrombotic complications in the radial artery.
Simulation of ozone–vegetation coupling and feedback in China using multiple ozone damage schemes
Authors: Cao Jiachen , Yue Xu , Ma Mingrui 
Published: April 2024

Abstract. As a phytotoxic pollutant, surface ozone (O3) not only affects plant physiology but also influences meteorological fields and air quality by altering leaf stomatal functions. Previous studies revealed strong feedbacks of O3–vegetation coupling in China but with large uncertainties due to the applications of varied O3 damage schemes and chemistry–vegetation models. In this study, we quantify the O3 vegetation damage and the consequent feedbacks to surface meteorology and air quality in China by coupling two O3 damage schemes (S2007 vs. L2013) into a fully coupled regional meteorology–chemistry model. With different schemes and damaging sensitivities, surface O3 is predicted to decrease summertime gross primary productivity by 5.5 %–21.4 % and transpiration by 5.4 %–23.2 % in China, in which the L2013 scheme yields 2.5–4 times of losses relative to the S2007 scheme. The damage to the photosynthesis of sunlit leaves is ∼ 2.6 times that of shaded leaves in the S2007 scheme but shows limited differences in the L2013 scheme. Though with large discrepancies in offline responses, the two schemes yield a similar magnitude of feedback to surface meteorology and O3 air quality. The O3-induced damage to transpiration increases national sensible heat by 3.2–6.0 W m−2 (8.9 % to 16.2 %), while reducing latent heat by 3.3–6.4 W m−2 (−5.6 % to −17.4 %), leading to a 0.2–0.51 °C increase in surface air temperature and a 2.2 %–3.9 % reduction in relative humidity. Meanwhile, surface O3 concentrations on average increase by 2.6–4.4 µg m−3, due to the inhibitions of stomatal uptake and the anomalous enhancement in isoprene emissions, the latter of which is attributed to the surface warming by O3–vegetation coupling. Our results highlight the importance of O3 control in China due to its adverse effects on ecosystem functions, global warming, and O3 pollution through O3–vegetation coupling.

Abstract. The new-generation atmospheric environment monitoring satellite DQ-1, launched successfully in April 2022, carries the Aerosol and Carbon Detection Lidar (ACDL), which is capable of globally profiling aerosol and cloud optical properties with high accuracy. The ACDL/DQ-1 is a high-spectral-resolution lidar (HSRL) that separates molecular backscatter signals using an iodine filter and has 532 nm polarization detection and dual-wavelength detection at 532 and 1064 nm, which can be utilized to derive aerosol optical properties. The methods have been specifically developed for data processing and optical property retrieval according to the specific characteristics of the ACDL system and are introduced in detail in this paper. Considering the different signal characteristics and different background noise behaviors of each channel during daytime and nighttime, the procedures of data pre-processing, denoising process and quality control are applied to the original measurement signals. The aerosol and cloud optical property products of the ACDL/DQ-1, including the total depolarization ratio, backscatter coefficient, extinction coefficient, lidar ratio and color ratio, can be calculated by the retrieval algorithms presented in this paper. Two measurement cases with use of the ACDL/DQ-1 on 27 June 2022 and the global averaged aerosol optical depth (AOD) from 1 June to 4 August 2022 are provided and analyzed, demonstrating the measurement capability of the ACDL/DQ-1.

Abstract. Understanding the intricate hydrological interactions between lakes and their surrounding watersheds is pivotal for advancing hydrological research, optimizing water resource management, and informing climate change mitigation strategies. Yet, these complex dynamics are often insufficiently captured in existing hydrological models, such as the bi-direction surface and subsurface flow. To bridge this gap, we introduce a novel lake–watershed coupled model, an enhancement of the Simulator of Hydrological Unstructured Domains. This high-resolution, distributed model employs unstructured triangles as its fundamental hydrological computing units (HCUs), offering a physical approach to hydrological modeling. We validated our model using data from Qinghai Lake in China, spanning from 1979 to 2018. Remarkably, the model not only successfully simulated the streamflow of the Buha River, a key river within the Qinghai Lake basin, achieving a Nash–Sutcliffe efficiency (NSE) of 0.62 and 0.76 for daily and monthly streamflow, respectively, but also accurately reproduced the decrease–increase U-shaped curve of lake level change over the past 40 years, with an NSE of 0.71. Our model uniquely distinguishes the contributions of various components to the lake's long-term water balance, including river runoff, surface direct runoff, lateral groundwater contribution, direct evaporation, and precipitation. This work underscores the potential of our coupled model as a powerful tool for understanding and predicting hydrological processes in lake basins, thereby contributing to more effective water resource management and climate change mitigation strategies.
Climatology of large hail in Europe: characteristics of the European Severe Weather Database
Authors: Hulton Faye , Schultz David M. 
Published: April 2024

Abstract. Large hail (greater than 2 cm in diameter) can cause devastating damage to crops and property and can even cause loss of life. Because hail reports are often collected by individual countries, constructing a Europe-wide large-hail climatology has been challenging to date. However, the European Severe Storm Laboratory's European Severe Weather Database provides the only pan-European dataset for severe convective-storm reports. The database is comprised of 62 053 large-hail reports from 40 CE to September 2020, yet its characteristics have not been evaluated. Thus, the purpose of this study is to evaluate hail reports from this database for constructing a climatology of large hail. For the period 2000–2020, large-hail reports are most prominent in June, whereas large-hail days are most common in July. Large hail is mostly reported between 13:00–19:00 local time, a consistent pattern since 2010. The intensity, as measured by maximum hail size, shows decreasing frequency with increasing hailstone diameter and little change over the 20-year period. The quality of reports by country varies, with the most complete reporting being from central European countries. Thus, results suggest that despite its short record, many indications point to the dataset representing some reliable aspects of the European large-hail climatology, albeit with some limitations.
Does a convection-permitting regional climate model bring new perspectives on the projection of Mediterranean floods?

Published: April 2024

Abstract. Floods are the primary natural hazard in the French Mediterranean area, causing damages and fatalities every year. These floods are triggered by heavy precipitation events (HPEs) characterized by limited temporal and spatial extents. A new generation of regional climate models at the kilometer scale have been developed, allowing an explicit representation of deep convection and improved simulations of local-scale phenomena such as HPEs. Convection-permitting regional climate models (CPMs) have been scarcely used in hydrological impact studies, and future projections of Mediterranean floods remain uncertain with regional climate models (RCMs). In this paper, we use the CNRM-AROME CPM (2.5 km) and its driving CNRM-ALADIN RCM (12 km) at the hourly timescale to simulate floods over the Gardon d'Anduze catchment located in the French Mediterranean region. Climate simulations are bias-corrected with the CDF-t method. Two hydrological models, a lumped and conceptual model (GR5H) and a process-based distributed model (CREST), forced with historical and future climate simulations from the CPM and from the RCM, have been used. The CPM model confirms its ability to better reproduce extreme hourly rainfall compared to the RCM. This added value is propagated on flood simulation with a better reproduction of flood peaks. Future projections are consistent between the hydrological models but differ between the two climate models. Using the CNRM-ALADIN RCM, the magnitude of all floods is projected to increase. With the CNRM-AROME CPM, a threshold effect is found: the magnitude of the largest floods is expected to intensify, while the magnitude of the less severe floods is expected to decrease. In addition, different flood event characteristics indicate that floods are expected to become flashier in a warmer climate, with shorter lag time between rainfall and runoff peak and a smaller contribution of base flow, regardless of the model. This study is a first step for impact studies driven by CPMs over the Mediterranean.
Lahar events in the last 2000 years from Vesuvius eruptions – Part 2: Formulation and validation of a computational model based on a shallow layer approach

Published: April 2024

Abstract. In this paper we present a new model for the simulation of lahars based on the depth-averaged code IMEX-SfloW2D with new governing and constitutive equations introduced to better describe the dynamics of lahars. A thorough sensitivity analysis is carried out to identify the critical processes (such as erosion and deposition) and parameters (both numerical and physical) controlling lahar runout using both synthetic and real case topographies. In particular, an application of the model to a syn-eruptive lahar from a reference size eruption from Somma–Vesuvius, affecting the Campanian Plain (southern Italy), described in Di Vito et al. (2024), is used in this work for the sensitivity analysis. Effects of erosion and deposition are investigated by comparing simulations with and without these processes. By comparing flow thickness and area covered by the flow and their evolution with time, we show that the modelling of both the processes is important to properly simulate the effects of the bulking and debulking as well as the associated changes in rheology. From a computational point of view, the comparisons of simulations obtained for different numerical grids (from 25 to 100 m), scheme order, and grain size discretization were useful to find a good compromise between resolution and computational speed. The companion paper by Sandri et al. (2024) shows an application of the presented model for probabilistic volcanic hazard assessment for lahars from Vesuvius deposits in the Neapolitan area.
Analysing 23 years of warm-season derechos in France: a climatology and investigation of synoptic and environmental changes
Authors: Fery Lucas , Faranda Davide 
Published: April 2024

Abstract. Derechos are severe convective storms known for producing widespread damaging winds. While less frequent than in the United States of America (USA), derechos also occur in Europe. The notable European event on 18 August 2022 exhibited gusts exceeding 200 km h−1, spanning 1500 km in 12 h. This study presents a first climatology of warm-season derechos in France, identifying 38 events between 2000 and 2022. Typically associated with a southwesterly mid-level circulation, warm-season derechos in France generally initiate in the afternoon and exhibit peak activity in July, with comparable frequencies in June and August. Predominantly impacting the northeast of France, these events exhibit a maximum observed frequency of 0.65 events per year, on average, within a 200 km by 200 km square region. These characteristics are similar to those observed in Germany, with notable differences seen in the USA, where frequencies can attain significantly higher values. The study also examines synoptic and environmental changes linked with analogues of the 500 hPa geopotential height patterns associated with past warm-season derechos, comparing analogues from a relatively distant past (1950–1980) with a recent period (1992–2022). For most events, a notable increase in convective available potential energy (CAPE) is observed, aligning with trends identified in previous studies for southern Europe. However, no consistent change in 0–6 km vertical wind shear is observed in the recent period. These environmental shifts align with higher near-surface temperatures, altered mid-level atmospheric flow patterns and often increased rainfall. The role of anthropogenic climate change in these changes remains uncertain, given potential influences of natural variability factors such as the El Niño–Southern Oscillation (ENSO) or the Atlantic Multidecadal Oscillation (AMO).

Abstract - After the declaration of the pandemic in March 2020, Governments around the world made social distancing a mandatory rule to practice to prevent the spread of coronavirus infection (covid-19). This action has impacted our lives in several ways, it can be stated that it might also have an impact on skin conditions or lead to skin conditions. The purpose of this survey was to assess if individuals practicing social distancing have experienced any dermatological changes. An online survey consisting of 16 questions was conducted to find out if the prolonged practice of social distancing has led to any skin conditions. 39.7 %( n=93) of individuals who took the survey stated that they have observed changes in their skin, hair, and nails, they stated that these skin changes were observed post-pandemic (p=0.00037). 33.8% (n=79) of participants stated that they are experiencing hair loss and 4.7% (n=11) of individuals noted to have observed vertical lines in their nails. Along with several factors like changes in the skincare routine, diet changes, mood changes, wearing masks, and excessive sanitization, the practice of social distancing has shown to impact changes in dermatological conditions in the pandemic. These conditions can be prevented with the right precautionary measures and can be treated under the care of a dermatologist while still practicing social distancing.

Authors: Astuti Nuraini Budi , Sari Yelfi Novita , Analia Devi 
Published: April 2024

A livelihood strategy contains steps to do something wisely and appropriately to achieve goals. To survive, rubber farmers cannot rely solely on rubber plantations; they must look for alternatives outside rubber farming. This study aimed to describe the livelihood resources and analyze the livelihood strategies of rubber farmers' households in Nagari Tanjung Bonai Aur Selatan during the rainy season. This study used a survey method, and the respondents were rubber farmers in Nagari Tanjung Bonai Aur Selatan, with a total of 40 respondents. The data analysis employed for this research was a quantitative and qualitative descriptive analysis. The results showed that the ownership of resources among rubber farmers in Nagari Tanjung Bonai Aur Selatan was in the medium category. In the rainy season, the livelihood strategy was primarily focused on increasing yields by intensifying agricultural land through clearing. The extensification strategy was carried out by becoming laborers, accounting for 13 (32,5%) households, while the diversification strategy involved activities such as sand collection and fish catching, representing 8 (20%) households of the respondents. However, migration was not a chosen strategy among rubber farmers in Nagari Tanjung Bonai Aur Selatan.
