Spatial–Temporal Variations in Temperature and Precipitation Extremes during 1960–2019 in Guizhou Province, China

Under the background of global warming, climate extremes have become a crucial issue with distinct heterogeneity features in different regions. Hence, spatial–temporal changes temperature and precipitation Guizhou Province were investigated utilizing daily maximums minimums data during 1960–2019 based on trend analysis. It was concluded that, firstly, all warm but spell duration indicator (WSDI) are significantly enhanced, whereas for cold extremes, monthly minimum value (TNn) is while cool nights (TN10P), frost days (FD0), ice (ID0), (CSDI) decreased. And consecutive wet (CWD) no significant variational Province. Secondly, trends more prominent robust western Temperature show large differences from spring to winter. Thirdly, closely correlated strength, area, westernmost ridge point index Pacific subtropical high (WPSH), correlation WPSH. The WPSH has strengthened shifted westward past 60 years, leading less total cloud cover downward solar wave flux reaching Earth’s surface, accordingly, exacerbating weakening extremes. These results will benefit understanding at regional scale.
