摘　　要：基于1961-2022年我国地面气象观测站逐日降水和气温资料,详细分析了2022年7月以来长江流域气温和降水的气候特征,利用气象干旱综合指数和区域干旱过程进行了统计分析,并与历史严重夏旱事件进行了比较。结果表明,2022年7月以来长江流域的夏伏旱持续时间长、影响范围大、程度重,是1961年以来长江流域发生的仅次于2011年的严重夏旱。鉴于此次干旱目前尚未结束以及干旱灾害影响的后延效应,其影响可能进一步加剧。Based on the daily precipitation and temperature data of China’s surface meteorological observation stations from1961 to 2022,the study analyzed in detail the climate characteristics of temperature and precipitation in the Yangtze River basin since July 2022,made statistical analysis using the meteorological drought comprehensive index and regional drought process,and compared with the historical serious summer drought events.The results showed that the summer drought in the Yangtze River basin since July 2022 has lasted for a long time,affected a vast area,and caused serious damage.The drought event in summer 2022 is the worst summer drought in the Yangtze River basin since 1961,which is second only to2011.Considering that the drought in the Yangtze River basin in 2022 has sustained till now,and the delayed effect of the drought disaster and its impact may be further intensified.
