What is the climate type in China? How to distinguish?

China is located in the southeast of Eurasia, the largest land in the world, facing the Pacific Ocean, the largest ocean in the world, with complex terrain and vast territory. From Altun Mountain in the west to Wusuli River in the east, it spans 63 longitudes. It starts from Mohe River in the north and reaches Zengmu shoal in the South China Sea in the south, with a latitude difference of 49 degrees between north and south. Therefore, the climate in China is very complicated and diverse. According to the classification of heat index, there are seven climate types in China: (1) equatorial monsoon climate. Located in the South China Sea Island area south of north latitude1o. The annual average temperature is above 26℃, the annual accumulated temperature reaches 9000℃, the temperature changes little, and the rainfall distribution in the four seasons is relatively uniform. (2) Tropical monsoon climate. Including southern Taiwan Province Province, Leizhou Peninsula and Hainan Island. The annual accumulated temperature is ≥8000℃, the average temperature in Leng Yue is not lower than 16℃, the annual extreme minimum temperature is not lower than 5℃ on average for many years, and the extreme minimum temperature is generally not lower than 0℃, and there is no frost all year round. (3) Tropical monsoon climate. North China and South China belong to this type of climate. The annual accumulated temperature is between 4500℃ and 8000℃, and the average temperature in Leng Yue is between -8℃ and 0℃, which is a transitional zone between subtropical zone and temperate zone. The temperature is quite high in summer (the average temperature is ≥25℃ for at least 6 periods, that is, 30 days) and quite low in winter. (4) temperate monsoon climate. Inner Mongolia and northern Xinjiang in China belong to this type of climate. The annual accumulated temperature is lower than 1600 ~ 3400℃, the average temperature in Leng Yue is -28 ~-8℃, and the average temperature in summer is still above 22℃, but rarely exceeds 25℃. (5) Cold temperate monsoon climate. The northeastern part of China belongs to this climate type. The annual accumulated temperature is lower than 1600℃, and the average temperature in Leng Yue is lower than -28℃. The cold degree in winter is worse than that in temperate zone, and the cold period is longer than that in temperate zone. (6) Plateau climate. The Qinghai-Tibet Plateau in China belongs to this type of climate. The annual accumulated temperature is lower than 2000℃, the daily average temperature is lower than 10℃, and the hottest temperature is also lower than 5℃ or even lower than 0℃. The daily temperature difference is large and the annual range is small, but the solar radiation is strong and the sunshine is sufficient. (7) Microclimate is the climate of gas layer and upper soil layer formed by the influence of underlying surface in some areas, also known as near-surface climate. The performance of this microclimate feature is microclimate phenomenon, and the main body of studying microclimate phenomenon is microclimate filial piety. More work has been done on the microclimate effect of these measures. Microclimate phenomenon is mainly manifested in the local differences between some meteorological elements and weather phenomena (such as radiation, temperature, humidity, wind, precipitation, fog and frost distribution, etc.). ), but it does not affect the whole weather process.
