The dividing line between monsoon climate and non-monsoon climate

The dividing line between monsoon climate and non-monsoon climate is introduced as follows:

The dividing line between monsoon area and non-monsoon area: Daxinganling, Yinshan, Helan, Bayan Kara and Gangdise. The east of the dividing line is the monsoon area, and the west is the non-monsoon area.

Monsoon area refers to the area where the climate is affected by monsoon. The terrain is dominated by plains, basins and hills. The reason is that the temperature difference between ocean and land surface has seasonal variation.

The East Asian monsoon region is complex, and the South China Sea-West Pacific belongs to the tropical monsoon region, with the northeast monsoon prevailing in winter and the southwest monsoon prevailing in summer.

Chinese mainland-Japan region belongs to subtropical monsoon region, with northwest monsoon prevailing in the north of 30 N in winter and northeast monsoon prevailing in the south. The southwest monsoon or southeast monsoon prevails in summer. There is abundant rainfall in summer and less rain and snow in winter, and the dry and wet seasons are not as obvious as those in tropical monsoon areas. ?

East Asian monsoon region is the most famous monsoon region in the world, which includes eastern China, Korea and Japan. Mainly because the Pacific Ocean is the largest ocean in the world, Eurasia is the largest continent in the world, and East Asia is in between, especially the temperature difference between land and sea and seasonal changes.

In winter, the Siberian high is strong, and the strong north wind at its front edge becomes the East Asian winter wind. In summer, the Asian continent is controlled by heating depression, and the Pacific subtropical high extends westward and advances northward. The southerly wind between high and low pressure becomes the summer monsoon in East Asia.

The East Asian monsoon has a great influence on the weather and climate in eastern China, Korea and Japan, forming an East Asian monsoon climate with cold and dry winter and high temperature and rainy summer.
