Abstract: Based on the daily precipitation and average temperature data from 156 national meteorological observation stations in Sichuan Province during 1961~2022, the monitoring and analysis of abnormal climate characteristics and the quantitative comprehensive evaluation of regional processes for high temperature and drought process in Sichuan Province in 2022 were carried out. The results showed that: (1) In the summer of 2022, the average temperature of Sichuan Province was 2.2 ℃ higher than that in the same period of the year, which was the highest in the same period of history since 1961. The average precipitation of Sichuan Province was 35% less than that in the same period of the year, which was the lowest in the same period of history since 1961. (2) 4 regional high temperature processes occurred in 2022 summer. Among the processes, the comprehensive intensity of regional high temperature events from July 28 to August 28, 2022 is the strongest since 1961. The cumulative intensity of annual high temperature process ranks the fourth in history since 1961, weaker than that in 2006. (3) In the summer of 2022, the drought was widespread, with more days above middle-level drought, and the percentage of comprehensive stations ranked the largest in the history of the same period. Three regional drought processes occurred in the Sichuan Province, among them, the comprehensive intensity of the regional drought process from August 7 to 26, 2022 is "strong", ranked 24th in history, failed to enter the top 10 in history, but exceeded the comprehensive intensity of the regional drought process from June 10 to July 9, 2006. From the perspective of impact region, the number of drought stations ranked the second in the same period in history, and the impact region was larger than that of the two regional drought processes in summer 2006.
