Mei-yu is a unique summertime weather phenomenon in East Asia. In China, Mei-yu in the middle-lower Yangtze River valley (YRV) region is typically characterized by continuous rainy weather from mid-June to early July, significantly impacting agriculture, economy, and people’s daily lives. In the context of global warming, abnormal Mei-yu weather has led to severe meteorological disasters in recent years.
Over the past 60 years, there has been a noticeable increase in the number of rainless days, precipitation intensity, and the frequency and intensity of extreme rainfall events during the Mei-yu season in YRV region. The most pronounced trend was the increase in precipitation intensity. This suggests that with global warming, the weather during the Mei-yu season has become more unpredictable and extreme.
