摘要
Heatwaves wreaked havoc across the Northern Hemisphere in summer 2022 and resulted in at least 15,000 deaths in Europe.Eastern China also experienced an unprecedentedly hot and dry summer.The maximum 2-m air temperature(Tmax)at around 300 national meteorological stations broke the historical re-cord,and high temperature warnings sounded for 41 consecutive days.As a consequence,a devastating chain of disasters took shape.With Tmax>40℃,more than 270 million people suffered from heat stress,and there were hundreds of casualties reported due to thermoplegia.The long-lasting heatwaves and pre-cipitation deficit subsequently led to severe drought in the Yangtze River basin.Decreased runoff reduced the hydropower generation by half in Sichuan Province.
