Abstract Drylands are home to more than 38% of the world's population and one most sensitive areas climate change human activities. This review describes recent progress in dryland research. Recent findings indicate that long‐term trend aridity index (AI) is mainly attributable increased greenhouse gas emissions, while anthropogenic aerosols exert small effects but alter its attributions. Atmosphere‐land interactions determine intensity regional response. The largest warming during last 100...
This study analyzes areal changes and regional climate variations in global semi-arid regions over 61 years (1948–2008) investigates the dynamics of change. The results reveal that largest expansion drylands has occurred since early 1960s. accounts for more than half total dryland expansion. area most recent 15 studied (1990–2004) is 7 % larger during first (1948–1962) period; this totaled 0.4 × 106 1.2 km2 within American continents Eastern Hemisphere, respectively. Although both regions,...
Abstract The effects of natural variability, especially El Niño-Southern Oscillation (ENSO) effects, have been the focus several recent studies on change drought patterns with climate change. interannual relationship between ENSO and global is not stationary can be modulated by Pacific Decadal (PDO). However, land distribution dry–wet changes associated combination PDO remains unclear. In present study, this investigated using a revised Palmer Drought Severity Index dataset (sc_PDSI_pm). We...
Abstract The amount, frequency and intensity of extreme precipitation over Xinjiang have increased dramatically under the wetting trend in Northwest China, but long‐term trends precipitation‐recycling process remain largely unexplored. Based on dynamic recycling model MERRA2 reanalysis, we revealed a mean ratio for 42.3% with growth rate 2.3% decade −1 during 1982–2019. increasing was almost equally attributed to (49%) external (51%). exhibited two peak centers, Tianshan Mountains region...
Abstract This study focuses on a new compounding concern, the sudden turn from drought to flood (STDF), that is becoming increasingly prominent. investigates long‐term trends and variability of STDFs in China during 1961–2020. The findings indicate are prevalent north northeast China, Yangtze River Delta (YRD). probability being followed by severe approaching 35% northern northeastern China. Since 1961, number has increased at rate average 2.8 events per decade. increase mainly occurred late...
Abstract. The Weather Research and Forecasting Model with chemistry (WRF-Chem model) was used to investigate a typical dust storm event that occurred from 18 23 March 2010 swept across almost all of China, Japan, Korea. spatial temporal variations in aerosols the meteorological conditions over East Asia were well reproduced by WRF-Chem model. simulation results further details processes related emission, long-range transport, radiative effects Taklimakan Desert (TD) Gobi (GD). indicated...
The world's oceans are under threat from the prevalence of heatwaves caused by climate change. Despite this, there is a lack understanding regarding their impact on seawater oxygen levels - crucial element in sustaining biological survival. Here, we find that can trigger low-oxygen extreme events, thereby amplifying signal deoxygenation. By utilizing situ observations and state-of-the-art model simulations, provide global assessment relationship between two types events surface ocean (0-10...
Abstract Central Asia (CA; 35°–55°N, 55°–90°E) has been experiencing a significant warming trend during the past five decades, which accompanied by intensified local hydrological changes. Accurate identification of variations in hydroclimatic conditions and understanding driving mechanisms are great importance for water resource management. Here, we attempted to quantify dry/wet using precipitation minus evapotranspiration ( P − E ) attributed based on atmosphere surface balances. Our...
Abstract Rapid warming over the Tibetan Plateau (TP) has been associated with an increasing trend in atmospheric water vapor content, which is critical for recharging Asian tower. However, mechanism wetting phenomenon remains unclear. Long‐term changes moisture balance and precipitation (PRE) recycling processes are investigated using ERA5 reanalysis from 1979 to 2019. The TP mainly due summer significantly increases western TP. Based on analysis, it found that PRE, evaporation, convergence...
Abstract Carbon dioxide ( CO 2 ), methane CH 4 and nitrous oxide (N O) are the three most important greenhouse gases GHG s), all show large uncertainties in their atmospheric budgets. Soils of natural managed ecosystems play an extremely role modulating abundance. Mechanisms underlying exchange these s at soil–atmosphere interface often assumed to be exclusively microbe‐mediated (M‐ s). We argue that it is a widespread phenomenon for soil systems produce through nonmicrobial pathways NM ‐ s)...
Abstract The rapid warming and consequent retreat of glaciers across the Tibetan Plateau (TP) have given rise to debate on ability atmospheric water supply alleviate depletion surface storage. We investigate long‐term changes in vapor balance TP using 40‐year fifth generation European Centre for Medium‐Range Weather Forecasts (ECMWF) (ERA5) reanalysis. Precipitation, convergence, evaporation generally maintain an equilibrium but with different variation trends: 0.68, −0.18, 0.69 mm/a,...
Abstract The ocean plays an essential role in regulating global and regional climate, which is mainly achieved through sea surface temperature anomaly (SSTA) changes. Studies on (GSST) are primarily carried out under linear assumption, not capable of fully revealing the evolution characteristics (SST) due to non‐linear non‐stationary nature SST. Here, GSST trend past century investigated by using adaptive local spatial–temporally multidimensional ensemble empirical mode decomposition method....
Abstract Most western Northwest China (WNWC) has experienced notable wetting in recent decades. Despite the widespread attention of scientific community, causes such climate shift are still not well‐understood. In this study, we find that dominant mode Indian Ocean sea surface temperature variability — Basin (IOBM) plays a crucial role precipitation over WNWC. Nonetheless, close lagged relationship is unstable, and varies with Pacific Decadal Oscillation (PDO). When PDO its warm phase, there...
This study focuses on a new compounding concern, the sudden turn from drought to flood (STDF), that is becoming increasingly prominent. Droughts usually end due increased precipitation, but if excessive rainfall occurs, it can lead secondary impacts already barren land, increasing likelihood of landslides and making farmland flooding significantly costlier than would have been only had occurred. Therefore, we must pay more attention compound disasters increase vulnerability populations...
The impact of asymmetric thermal forcing associated with land–sea distribution on interdecadal variation in large-scale circulation and blocking was investigated using observations the coupled model intercomparison project outputs. A index (LSI) defined to measure zonal forcing; changed from a negative positive anomaly 1980s. In phase LSI, 500 hPa geopotential height decreased polar regions increased mid-latitudes. tropospheric planetary wave activity also became weaker exerted less easterly...
The source area of the Yellow River Basin (SYRB) is located in northeastern Tibetan Plateau, and precipitation SYRB great importance to water resources throughout whole basin. By analyzing summer SYRB, we found that an 11.4% increase occurred during 2003–2019 compared with 1982–2002. Such interdecadal was due significant changes moisture contribution from external source. In past 38 years, 95.4% vapor for precipitable came local evapotranspiration (10.6%), Plateau (35.8%), central Eurasian...
