Summary: Climate change has significant impacts on vegetation and livelihoods, particularly in dryland areas. This study uses remote sensing and GIS analysis to simulate the effects of temperature and precipitation on vegetation dynamics in Katsina State, Nigeria. The results demonstrate increasing temperatures, decreasing precipitation, and a more adverse trend under the RCP8.5 scenario.

Summary: This study investigated the temperature and precipitation changes in Xinjiang and its sub-regions from 1960 to 2019 using the Mann-Kendall method and cross-wavelet analysis. The results showed significant warming and wetting trends in the region. Climate change in Xinjiang was closely related to atmospheric circulation, with the subtropical high, Northern-Hemisphere polar vortex activities, and the Tibetan Plateau playing a significant role.

Summary: The study shows that the new-generation models simulate present-day temperature and precipitation extremes reasonably well and project more frequent and intense hot temperature and precipitation extremes in the future due to global warming. The changes in temperature and precipitation extremes are mostly influenced by global annual mean surface air temperature, with regional variations observed.

Summary: This study investigates the spatial and temporal variation characteristics of extreme precipitation in the Jianghuai region. The results show significant increasing trends in maximum one-day precipitation amount, extreme wet days, and simple precipitation intensity index. The intensity of extreme precipitation has significantly increased, with different trends observed in different regions. The study also identifies the most influential factors on extreme precipitation, including the North Atlantic Oscillation and East Asian summer monsoon. The findings have important implications for water-resource management and disaster prevention and control in the Jianghuai region.

Summary: Precipitation in the Three-River Headwater region has shown an increasing trend during the cold season from 1961 to 2014, with a dry-to-wet shift around the late 1980s. The increased precipitation is associated with enhanced easterly anomalies over the Tibetan Plateau and southeasterly water vapor transport. Enhanced Walker circulations and changes in sea surface temperature gradients in tropical oceans are contributing factors to the precipitation changes in the region.

Summary: Based on the standardized precipitation evapotranspiration index (SPEI), the number of drought days in China has significantly increased after the mid-1990s, mainly in the zonal belt from southern Xinjiang to southern Northeast China and North China. There is also a continuous increase in drought days in the meridional belt from eastern Northwest China to eastern Southwest China. The increase in drought days is closely related to the warming in the zonal belt and both temperature increase and precipitation decrease in the meridional belt.

Summary: This study aims to explore the atmospheric dynamic processes leading to the concurrence of humid heat extremes, which may exacerbate the risk from heat stress in today's interconnected world. In specific regions over the Northern Hemisphere midlatitudes, durations of humid heat extremes are found to be elevated simultaneously by amplified quasi-stationary waves. We further identify the physical connections between amplified quasi-stationary waves and humid heat extremes over targeted regions. This would help in better understanding the role of changing atmospheric circulations in the humid heat extremes.

Summary: The characteristics and mechanisms of extreme precipitation events over central Asia are investigated based on daily data and percentile criteria. The results show that the extreme precipitation events have a life cycle of about 10 days. The precipitation signal is weak but significant from eight to two days before the peak, and it amplifies rapidly and reaches its peak in two days. The earliest precipitation signal appears over the northwest of central Asia and moves southeastward. The extremes are closely tied to a quasi-stationary planetary wave train emanating from the North Atlantic and the resultant disturbed Asian subtropical jet.

Summary: The study found that the North Indian atmospheric diabatic heating variation has a significant impact on summer rainfall in Central Asia, specifically on the position of the southward subtropical westerly jet and water vapor transportation. The changes in the position of the subtropical westerly jet are mainly influenced by atmospheric diabatic heating over northern India.

Summary: This study investigates the association between daily precipitation extremes (PEX) and maximum daily temperature (T), dew point temperature (DPT), and precipitable water (PW) in India from 1979 to 2016. The relationship between PEX and physical covariates is modeled using copula for selected cities with different climates. The largest scaling coefficients are observed in Mumbai, with negative scaling with T and positive scaling with DPT. The median value of rainfall extremes increases with decreased T and DPT, but increases with increased PW for all cities. Future scaling analyses using ensemble mean of 13 General Circulation Models (GCMs) show negative to slight positive scaling with T across India.

Summary: This study reveals a significant association between the Atlantic Meridional Mode (AMM) and temperature variability in the eastern European region. Positive AMM phase leads to a significant increase in temperature, while negative phase has the opposite effect. The AMM modulates the temperature through planetary-scale Rossby waves and anomalous anticyclone circulation.

Summary: This study presents a diagnostic analysis of the interannual variation of regional climate and its impact on biomass burning aerosol emissions in peninsular Southeast Asia (PSEA). It identifies four climatic factors governing the emission and transport of PSEA biomass burning aerosols and reveals a significant correlation with the El Nin similar to o-Southern Oscillation (ENSO). The results contribute to a better understanding and improved model simulations of aerosol-climate interactions in South and Southeast Asian monsoon regions.

Summary: Reliable precipitation information is crucial for scientific and operational applications. Open-access gridded precipitation products (OGPPs) are important sources due to their continuous spatiotemporal coverage. This study proposes a methodology to comprehensively compare the accuracies and stabilities of ten different OGPPs, particularly in mountainous basins. The results show high accuracy but unstable performance of all OGPPs, with multi-source fusion-type products offering better stability and accuracy. Multi-source weighted-ensemble precipitation and climate prediction center morphing method products exhibit the best comprehensive performance.

Summary: This study, based on reanalysis data from 1980 to 2019, reveals that the relationship between autumn sea ice concentration in the Barents-Kara Seas (BKSIC) and subsequent winter North Atlantic Oscillation (NAO) underwent an interdecadal weakening in the early 1990s. The weakening can be attributed to the decrease in the interannual variability of BKSIC, which leads to a discrepancy in the tropospheric warming. In the former period (1980-1993), the decrease in autumn BKSIC enhances tropospheric warming and weakens the circumpolar westerly, resulting in a negative NAO phase. However, in the latter period (1994-2019), the smaller interannual variability of BKSIC weakens its influence on the tropospheric temperature, diluting the relationship with the subsequent winter NAO.

Summary: Significant phase shifts in winter surface air temperature (SAT) anomalies have occurred in East Asia in recent years, leading to detrimental effects on socio-economic activities. In this study, the fourth principal mode of month-to-month SAT variations over EA in winter was identified, representing subseasonal SAT reversals over the mid-high latitudes of EA during late winter. The formation of this mode is accompanied by stratospheric temperature anomalies over eastern Siberia-Alaska in January.
