The average precipitation in the province is 62 mm to 67 mm, which is more than normal. It is estimated that there will be four rainy weather processes in April, among which, from April 14 to April 16, the daily average temperature will drop by 3℃ to 5℃, with moderate rain in the western Sichuan Plateau and Panxi, partial heavy rain, moderate rain in the northwest and southwest of the basin and light rain in the rest of the province.

East Sichuan, that is, Sichuan Basin and its surrounding mountainous areas, belongs to the humid climate zone in the middle subtropical zone and has maritime climate characteristics. This area is warm and humid all the year round, with an annual average temperature of 16 ~ 18℃, a daily temperature of ≥ 10℃ lasting for 240 ~ 280 days, a cumulative temperature of 4,000 ~ 6,000℃, a small daily temperature difference, a large annual temperature difference, warm in winter and hot in summer, and a frost-free period of 230 ~ 340. There are more clouds and less sunny days in the basin. The sunshine time in 20 13 years is short, only 1000 ~ 1400 hours, which is 600 ~ 800 hours less than that in the lower reaches of the Yangtze River basin at the same latitude.
