How is China’s climate distributed?

1. Tropical monsoon

Including the southern part of Taiwan Province, Leizhou Peninsula, Hainan Island and Xishuangbanna. The annual accumulated temperature is >= 8000℃, the average temperature of the coldest month is not less than 15℃, the annual extreme minimum temperature is not less than 5℃ on average for many years, the extreme minimum temperature is generally not less than 0℃, and there is no frost all year round.

2. Subtropical monsoon

Most areas in South China and East China have this type of climate. The annual accumulated temperature is between 4500--8000℃, and the average temperature of the coldest month is 0--15℃. It is the transition zone between the subtropical zone and the temperate zone. The summer temperature is quite high (the average temperature of the period is >= 25℃ for at least 6 periods. i.e. 30 days), the temperature is quite low in winter.

3. Temperate monsoon

North China has this type of climate. The annual accumulated temperature ranges from 3000 to 4500°C, with the average temperature in the coldest month ranging from -28 to 0°C. Most of the average summer temperatures still exceed 22°C, and those exceeding 25°C are rare, so it is relatively warm and cool. In recent years, due to climate warming and other reasons, high temperature weather has occurred frequently in southern North China, but the average temperature still does not exceed 25°C.

4. Plateau and mountainous areas

China's Qinghai-Tibet Plateau has this type of climate. The annual accumulated temperature is lower than 2000°C, the daily average temperature is lower than 10°C, and the hottest temperature is lower than 5°C, or even lower than 0°C. The daily temperature range is large but the annual range is small, but the solar radiation is strong and the sunshine is sufficient.

5. Temperate continental climate

The broad temperate continental climate includes temperate desert climate, temperate steppe climate and subarctic coniferous forest climate. The narrow concept excludes the humid latter. Most of China's inland areas north of 40° north latitude have a temperate continental climate. Precipitation is scarce in these areas, with annual precipitation ranging from 300 to 500 mm. The daily and annual temperature ranges are large, such as Xinjiang in my country.

6. Tropical Rainforest

China's Nansha Islands have this type of climate. It is hot and rainy all year round with abundant precipitation. The average annual temperature is 28 to 30 degrees Celsius and the annual precipitation is more than 2800 mm.

China's climate distribution characteristics

China is a monsoon climate area, and the temperature distribution in winter and summer is very different. The temperature distribution characteristics are: the temperature is generally low in winter, hot in the south and cold in the north, and the temperature difference between the north and the south is large, exceeding 50℃. The main reason is that the sun shines directly on the southern hemisphere in winter, and the northern hemisphere receives less solar energy;

The influence of latitude: the winter monsoon prevails in winter. High temperatures prevail in most parts of the country in summer (except for the Qinghai-Tibet Plateau), and there is not much temperature difference between the south, the north, and the north.

The main reasons are: the sun shines directly on the northern hemisphere in summer, and the northern hemisphere gets more heat; the summer monsoon prevails in summer, and the temperature rises to the highest value in most parts of my country; the height of the sun is high in summer, and the higher the latitude, the longer the daytime. Slow down the difference in solar heat received between the north and the south. The coldest place in winter is Mohe Town, and the hottest place in summer is Turpan. Chongqing, Wuhan, and Nanjing are known as my country's "three furnaces."

Frost-free period and growing period: Generally speaking, the frost-free period in various parts of my country gradually shortens from south to north and from the coast to the inland.

The longer the frost period, the longer the growth period of crops. On the contrary, it is short.
