Drought events are increasingly frequent and severe in Yunnan, affecting the livelihoods and economies of millions of people across the province. To mitigate the associated impacts, understanding the characteristics of drought and discussing its possible causes has become a crucial research focus. This study, therefore, analyzes the drought characteristics and the underlying influence of extratropical sea surface temperature (...

The impact of tropopause folds (TFs) on the regional extreme cold events (RECEs) in Yunnan Province is examined. This province is situated in China's Low‐Latitude Highlands (CLLH). In the 60‐year period 1961–2020, 140 RECEs in Yunnan are identified from the air temperature measurements at 125 meteorological observation sites. Among these RECEs, 115 events are accompanied by TFs in the CLLH and referred to as TF‐type events and...

The frequency and intensity of heatwaves over southwestern China during spring and early summer have been increased significantly during 1980–2022. Until now, the physical mechanisms for these changes in heatwaves remain unclear. Here, we show that these increases in heatwaves can be attributed to the changes in both local soil moisture–temperature coupling processes and teleconnection patterns across Eurasia. On the one hand,...
