Yunnan has a cold temperate tropical climate. Why is there so much climate in Yunnan? There are two kinds of cold weather in a place, one is caused by the sun, and the other is special geographical conditions. On the earth, due to the inclination of the earth axis, the earth has been circulating in the circulating sun, and its posture has not changed, so an included angle of 23.26 degrees is formed between the equator and the sun, and the sun moves directly up and down on the equator in this area. This area is called North and South. The tropic of cancer from 23.26 degrees south latitude to 23.26 degrees south latitude. In this respect, that place is summer, not winter, and the inseparable places are spring and autumn.

People call it the tropics in the low latitudes of the Tropic of Cancer. The mid-latitude region of the Tropic of Cancer is 60 degrees, which is called the north temperate zone and the south temperate zone. The height above 60 degrees is Nandatang, and the north is cold. Most of my country is in the north temperate zone, and only a few areas are in the tropics, but why is Kunming a spring climate? This is because of the special geographical conditions in Kunming. The altitude of Kunming is between1500 and 2800, with an average level of 189 1 m. In summer, when the sun is close to direct sunlight, there should be high temperature, but the temperature is much lower due to high altitude and tropical monsoon.

On our ground, every time 100 meters rises, the temperature drops by 0.6 degrees, and when 1000 meters is high, the temperature in Kunming can drop by nearly 10 degrees, and the temperature is naturally pleasant. The higher the sea level, the lower the temperature, the higher the sea level and the worse the air. The temperature is directly proportional to the density and activity of molecules and particles. When sunlight shines in thin air, it absorbs and stores less heat. Summer in Kunming belongs to tropical monsoon climate. It is influenced by the wind and humidity in the southwest Indian Ocean. Clouds are covered with fog, which weakens the solar radiation. There is less sunshine and the rain is taken away. It is very cool this summer. Kunming is located on the plateau, and it will be colder in winter. However, due to the geographical conditions in Yunnan, Leng Bo rarely invaded, and the latitude and sufficient sunshine made the average temperature 10℃.

The reason why Leng Bo rarely invades Kunming is that the mountains in northern Yunnan, such as Liangwangshan, Wushushan and Qinghai-Tibet Plateau, make the cold air in the north go south, so the winter is sunny, the air is dry and sunny, and it will not be as cold or hot as spring. The four-season spring light in Kunming is representative in Yunnan, but it can only represent the clouds in Yunnan. There is no such blessing in other regions. Northwest Yunnan has a cold tropical climate, winter is not summer, and spring and autumn are short; Duana in western Yunnan is a low-grade river area, and some rivers enter tropical areas. There is no winter in Changshan. Yunnan is a good place with a very special climate, and it is known as Yunnan Wonderland. Some places can experience four seasons in one day. Friends who haven't arrived really need to experience it.
