What's the climate like in southern Sichuan, Tibet?

The subtropical monsoon humid climate is distributed on the east coast of subtropical continent, especially in the middle and lower reaches of the Yangtze River in China. The seasonal variation of temperature is obvious. In winter, monsoon from northwest China prevails, with high air pressure and little rain. In summer, due to the rapid warming of the mainland and the low air pressure, it attracts the southeast monsoon from the sea, so there is more precipitation. There is frontal rain at the intersection of cold and warm air masses in early summer, convective rain in midsummer and typhoon rain at the turn of summer and autumn. So there is more precipitation in the whole summer. Judging from the temperature, the average monthly temperature is above 0℃ in winter and above 28℃ in summer. The annual precipitation is more than 800 mm, and the natural vegetation is subtropical evergreen broad-leaved forest. This climate is also distributed in southeastern North America and eastern Argentina in South America.

China's Qinling Mountains, south of Huaihe River, north of Nanling Mountain, east of Qinghai-Tibet Plateau, south of Japanese archipelago and a small part of Korean peninsula all belong to this climate. For example, Deyang, Mianyang and Suining in the hilly areas of central Sichuan, Chongqing and Yichang in the middle and lower reaches of the Yangtze River, Wuyishan in Fujian, Longyan, Xiamen and Jinhua Lake in Zhejiang, Anhua in Hunan and Ganzhou in Jiangxi in the hilly areas of southeast China, and Kyushu, Shikoku and Ryukyu Islands in southern Japan (ownership is disputed).
