What are the characteristics of climate resources?

Include southern Taiwan Province Province, Leizhou Peninsula, Hainan Island and Xishuangbanna. Annual accumulated temperature >; =8000℃, the average temperature in Leng Yue is not lower than 15℃, 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.

2. Subtropical monsoon

China, South China and East China all belong to this climate type. The annual accumulated temperature is between 4500-8000℃, and the average temperature in Leng Yue is 0- 15℃, which is a transitional zone between subtropical zone and temperate zone, and the summer temperature is quite high (average temperature >; =25℃ for at least 6 days, that is, 30 days), and the temperature is quite low in winter.

3. Temperate monsoon

North China belongs to this climate type. The annual accumulated temperature is between 3000 and 4500℃. The average temperature in Leng Yue is between-28 and-0℃, and the average temperature in summer is still above 22℃. The temperature over 25℃ is relatively rare and relatively warm and cool. In recent years, due to climate warming and other reasons, high temperature weather frequently occurs in southern North China, but the average temperature still does not exceed 25℃.

4. Temperate continental nature

The generalized temperate continental climate includes temperate desert climate, temperate grassland climate and sub-frigid coniferous forest climate. In a narrow sense, except for the latter, most of the inland areas of China north of 40 north latitude have temperate continental climate. Precipitation in these areas is scarce, with an annual precipitation of 300-500mm, with large daily and annual temperature differences, such as Xinjiang.

5. Tropical rain forest

Nansha Islands in China belong to this type of climate. It is hot and rainy all year round, with abundant precipitation. The annual average temperature is 28 to 30 degrees, and the annual precipitation is more than 2,800 millimeters.

Extended data:

The eastern monsoon region is hot and rainy in summer, the northwest region is hot and dry in summer, and the Qinghai-Tibet Plateau region is cool and rainy in summer.

Due to the difference of thermal characteristics between the mainland and the ocean, a cold high pressure is formed in the inland of Asia, and a hot low pressure is formed in the eastern and southern oceans. If the air in the high-pressure area flows to the low-pressure area, it will form the northerly and northwest winds in winter in China.

On the contrary, in summer, the continent is hot in the ocean, the high-temperature continent becomes a low-pressure area, and the cool ocean becomes a high-pressure area. Therefore, the southeast wind or southwest wind from the ocean to the mainland prevails in summer in our country. Because mainland winds bring dry airflow and ocean winds bring humid air, precipitation in China mostly occurs from May to September in summer when the south wind prevails.

It can be seen that the characteristics of China monsoon are not only reflected in the change of wind direction, but also in the change of dryness and wetness. The monsoon climate in China is characterized by hot Leng Xia in winter, dry winter and rainy summer. This climatic feature of the same season of rain and heat is very beneficial to agricultural production. Winter crops have been harvested or stopped growing, and generally do not need much water. Summer crops grow vigorously, which is the season that needs a lot of water.
