Influence of Terrain on Climate in China

China's topography is high in the west and low in the east, which is inclined to the ocean, which is conducive to the humid air flowing from the sea to the inland of China and bringing abundant precipitation to the vast areas of China. ?

I. Environment:

China is high in the west and low in the east. Mountains, plateaus and hills account for 67% of the land area, while basins and plains account for 33% of the land area. The mountains are mostly east-west and northeast-southwest, mainly including Altai Mountain, Tianshan Mountain, Kunlun Mountain, Karakorum Mountain, Himalayan Mountain, Yinshan Mountain, Qinling Mountain, Nanling Mountain, Taiwan Province Mountain and Hengduan Mountain. ?

There is the highest Qinghai-Tibet Plateau in the world in the west, with an average elevation of more than 4,000 meters. It is called "the roof of the world", and Mount Everest is 8848 meters above sea level, which is the highest peak in the world. Inner Mongolia, Xinjiang, Loess Plateau, Sichuan Basin and Yunnan-Guizhou Plateau in the north and east are the second steps of China's topography. ?

2. What is the climate type of China?

1, tropical monsoon:?

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. Plateau Mountain:?

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.

5. Temperate continental:?

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, and the daily temperature range is large, such as Xinjiang in China.

6. 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.

What influence does topography have on our country?

1, climate:?

China's topography is high in the west and low in the east, which is inclined to the ocean, which is conducive to the humid air flowing from the sea to the inland of China and bringing abundant precipitation to the vast areas of China.

2. rivers:?

As the saying goes, "Man struggles upwards, water flows downwards", and the terrain of China is high in the west and low in the east, which will inevitably cause rivers in China to flow into the sea from west to east. As the ancient poem goes, "One spring water flows eastward" and "One spring water never returns".

3. Transportation:?

On the one hand, the big river flowing eastward communicates the traffic between the east and the west of China and facilitates the connection between the coast and the inland; On the other hand, the mountain range at the junction of stairs has become a huge obstacle to the east-west traffic in China.
