The climatic characteristics of Nanchang from June to August are briefly described, and its causes are analyzed.

In early summer (from June to early July), it is rainy and rainy, with frequent rainstorms and heavy and concentrated rainfall. The reason is that the subtropical high ridge line is located near 20 degrees north latitude, and the summer monsoon rain belt goes north to the middle and lower reaches of the Yangtze River, ushered in the rainy season.

In midsummer (from mid-July to late August), it is sunny and hot with little rain, and there is often continuous high temperature weather, and the precipitation is obviously reduced. After the rainy season, the subtropical high jumped northward and Nanchang was controlled by the subtropical high.
