Kunming is located in Yunnan-Guizhou Plateau, with an altitude of nearly 2000 meters. Although it is close to the tropics, the altitude offsets the influence of low latitude. This is also one of the reasons why it is cooler in summer; Kunming is in the southwest of China. In summer, there is a southwest monsoon from the Indian Ocean, which brings a lot of water vapor and often rains. Clouds and rain weaken the solar radiation, and the evaporation of rain also takes away a lot of heat, so the ground temperature is not high. In winter, due to Kunming's low latitude (25 degrees north latitude) and strong solar radiation, there is a southwest warm current from the southwest of the Asian continent to send heating to Kunming. Under the influence of the dry southwest warm current, there is plenty of sunshine and little rain, so there is plenty of sunshine and a mild climate. There are Wangliangshan Mountain and Wumeng Mountain in the north of Kunming, which block the invasion of cold air from north to south, so there are few cold days in winter.
