In which month does the rainy season in Jiangxi occur?
In May to June, Jiangxi is located in the middle and lower reaches of the Yangtze River where plum rains prevail.
Every year from May to June, the weather continues to be cloudy and rainy in the Yangtze River Basin in southern mainland China (the middle and lower reaches of the Yangtze River and the eastern Sichuan Basin), the Jianghuai region, Taiwan, central and southern Japan, and southern Korea. natural climate phenomena.
After the rainy season, the weather in Central China, Japan, South Korea, Taiwan and other places begins to be dominated by the Pacific high pressure, officially entering the hot summer. Climate characteristics:
The climate is a warm and humid subtropical monsoon climate, with an average annual temperature of about 16.3-19.5°C, generally increasing from north to south. The average annual temperature in the mountainous areas of northeastern and northwest Jiangxi and the Poyang Lake Plain is 16.3-17.5℃, while in the southern Jiangxi basin it is 19.0-19.5℃. The summer is long, and the average temperature in July is 28.0-29.8°C, except for the mountainous areas around the province, which is 26.9-28.0°C. The extreme maximum temperatures are almost all above 40°C, making it one of the hottest areas in the middle reaches of the Yangtze River.
Winter is short. The average temperature in January is 3.6-5.0℃ in the Poyang Lake Plain in northern Jiangxi and 6.2-8.5℃ in the southern Gansu Basin. The province has warm winters and hot summers, with a frost-free period of 240-307 days. The duration of the daily average temperature stabilizing above 10°C is 240-270 days, and the active accumulated temperature is 5000-6000°C. It is very beneficial to the development of the three-cropping system, mainly double-cropping rice, and the development of temperature-loving subtropical economic trees. Only the northern terrain is open, which will have adverse effects when a particularly severe cold wave invades the south.
Jiangxi is one of the rainiest provinces in China. The annual precipitation is 1341-1943 mm. The regional distribution is more in the south and less in the north, more in the east and less in the west; there are many mountains and few basins. Lushan Mountain, Wuyi Mountain, Huaiyu Mountain and Jiuling Mountain are the four rainy areas in the province, with an average annual precipitation of 1700-1943 mm. De'an is a drier area with an average annual precipitation of 1,341 mm. The seasonal distribution of precipitation is uneven, with April to June accounting for about 42-53%. The inter-annual variability of precipitation is also great. The difference between years with heavy rain and years with little rain is almost doubled. The two are one of the reasons for the frequent occurrence of droughts and floods in Jiangxi. one.
