2023: Weather and Climate Extremes Hitting the Globe with Emerging Features
Globally, 2023 was the warmest observed year on record since at least 1850 and, according to proxy evidence, possibly of the past 100 000 years. As in recent years, the record warmth has again been accompanied...

Open AccessExtreme dry advection dominates the record-breaking Yangtze River heatwave in midsummer of 2022
The Yangtze River Valley (YRV) experienced an unprecedented heatwave in midsummer of 2022. Still, the detailed physical processes involved in the influence of abnormal large-scale atmospheric circulation on th...

Understanding and Attribution of Extreme Heat and Drought Events in 2022: Current Situation and Future Challenges
Extreme weather events and their consequential impacts have been a key feature of the climate in recent years in many parts of the world, with many partly attributed to ongoing global-scale warming. The past y...

Open AccessExtremely hot East Asia and flooding western South Asia in the summer of 2022 tied to reversed flow over Tibetan Plateau
In the summer (July and August) of 2022, unprecedented heat wave occurred along the Yangtze River Valley (YRV) over East Asia while unprecedented flood occurred over western South Asia (WSA), which are located...

Detectable anthropogenic forcing on the long-term changes of summer precipitation over the Tibetan Plateau
Precipitation changes over the Tibetan Plateau (TP), “Asian Water Tower”, greatly affect water resources of the surrounding countries. A dipole pattern in summer precipitation trend over the TP is observed for...

Moisture Origins and Transport Processes for the 2020 Yangtze River Valley Record-Breaking Mei-yu Rainfall
The summer of 2020 recorded a record-breaking flood due to excessive mei-yu rain falling over the Yangtze River Valley (YRV). Using the Lagrangian model FLEXPART, this paper investigates moisture sources and t...

Open AccessClustering circulation in eastern Asia as a tool for exploring possible mechanisms of extreme events and sources of model error
Every summer in eastern Asia, the combined effects of complex topography, multiple potential moisture sources and a mixture of sub-tropical and mid-latitude dynamics produces an environment, in which subtle di...

Open AccessObservationally constrained projection of the reduced intensification of extreme climate events in Central Asia from 0.5 °C less global warming
Arid Central Asia is highly vulnerable to extreme climate events. Information on potential future changes in extreme climate events in Central Asia is limited. In this study, the performances of models from th...

Synoptic-scale atmospheric circulation anomalies associated with summertime daily precipitation extremes in the middle–lower reaches of the Yangtze River Basin
The mechanisms of short-lived precipitation extremes in boreal summer over the middle–lower reaches of the Yangtze River Basin (MLYRB) during 1961–2014 are explored using gridded observational and reanalysis d...

Increasing Flash Floods in a Drying Climate over Southwest China
In a globally warming world, subtropical regions are generally expected to become drier while the tropics and mid–high latitudes become wetter. In line with this, Southwest China, close to 25°N, is expected to...
