The first high temperature period in North China and the Huang-Huai region (between the Yellow River and the Huai River) has arrived earlier than usual this year. Based on the current assessment of meteorological disaster risks, by July 14 China will face compound disasters such as high temperature combined with heavy rain, drought, etc., and this summer may still be extremely hot. The onset date of regional extreme hot days nationwide is advancing at a rate of about 2.5 days per decade. This year, it occurred four days earlier than normal.
Due to climate change, atmospheric circulation has become more complex, increasing the frequency and intensity of extreme weather events. Globally, multiple disasters are overlapping to create compound events, such as high temperature with drought and low temperature with freezing, showing the characteristics of complexity, large-scale impact, and long-term consequences.
