Basic characteristics of climate in China.

Regarding the diversity of climate in China, its basic characteristics are as follows:

1, China's climate is influenced by geographical location and topography, showing obvious differences between east and west. The climate in the eastern coastal areas is mild and humid, with four distinct seasons, hot and humid in summer, cold and rainy in winter, and more annual precipitation. However, the climate in the western plateau and mountainous areas has obvious plateau and mountainous characteristics.

2. The temperature changes greatly, the precipitation is unevenly distributed, the temperature difference between day and night is large, and the climate is dry. Northwest China is famous for its coexistence of drought and cold, low temperature and scarce precipitation. The temperature distribution in the south and north of China is quite different. It is hot in Leng Xia in winter in northern China, and the temperature changes obviously. The climate in southern China is warm and humid, with four distinct seasons and high annual average temperature.

3. The middle and lower reaches of the Yangtze River are also affected by monsoon, which is hot and rainy in summer and cold and dry in winter. Because of its vast territory, China has different climate types. For example, the northern region has a temperate monsoon climate, while the southern region is dominated by tropical monsoon and subtropical monsoon climate.

4. Southwest belongs to subtropical mountain monsoon climate, northwest belongs to temperate continental climate, and Qinghai-Tibet Plateau belongs to plateau climate. The existence of these climatic types leads to the diversity and richness of our country. The distribution of climate precipitation in China is unbalanced, showing obvious characteristics of less in the east, more in the south and less in the north.

Basic knowledge of climate

1. The main factors that make up the climate are solar radiation, atmospheric circulation, land and sea distribution, topography, ocean currents and human activities. Solar radiation is the basic factor affecting climate. Because the earth is a big sphere, the angle of the sun at different latitudes is different. Some places are direct, some places are oblique, and some places have not been exposed to the sun all day or for months.

2. The altitude angle of the sun varies from place to place, so the amount of light and heat of the sun are different, and the temperature is also very different. Atmospheric circulation is the main factor that forms various climate types and weather changes. The air in the atmosphere moves at different scales, which is collectively called atmospheric circulation.

3. The distribution of land and sea changes the zonal distribution of temperature and precipitation. Terrain fluctuation will destroy the zonality of climate distribution. Ocean currents also have a certain influence on the climate along the coast of the continent through which they flow. Human activities will also have a certain impact on the formation and distribution of climate.
