Causes of gale in northwest China.

Question 1: The spring gale in northwest China is caused by the Asian high;

Second, there is little vegetation on the surface, which has little blocking effect on strong winds;

Third, the temperature rises in spring and the cyclone activity increases.

Question 2: What are the natural causes of sandstorms in northwest China? Northwest China is located inland, water vapor is difficult to reach, precipitation is scarce, climate is dry and vegetation is poor; In winter, due to northerly winds, there are many sandstorms; In summer, influenced by the westerly belt, it is dry and windy when the westerly wind trudges to the northwest of China.

Question 3: Please analyze the causes of windy weather in northwest China from a natural point of view. The northwest is backed by the cold high pressure of the Mongolian Plateau, and the high pressure wind in the South Pacific is low, so the northwest wind is strong.

Question 4: What are all possible reasons for the abundant northwest wind resources? If we only pay attention to the drought, we can only explain it this way: there is little water and vegetation in the drought-stricken areas, and there are few obstacles to air circulation. On the contrary, wet places have more vegetation, more obstacles and less wind.

Question 5: Why is the wind in northwest areas such as Inner Mongolia, Gansu and Xinjiang 1? The cold wind in the north is blowing from Siberia. The wind is relatively strong and the low temperature is an environmental factor. There are few trees in Inner Mongolia, Gansu and Xinjiang, and there is no shelter from trees, so the wind is naturally strong.

Question 6: The reason why the wind in Alashankou is strong is that it is transparent from north to south.

Alashankou, called Junggar Pass in Russia, is a mountain pass between Alatao Mountain and baruch Mountain, and also a frontier fortress and port between China and Kazakhstan.

Alashankou is 90 kilometers long and 20 kilometers wide. The local area is also famous for its strong winds. Gale weather above magnitude 8 lasts for more than 180 days all the year round, and the maximum instantaneous wind power can reach 12 to 13. Guodian Group has built a * * * 1.5 million kilowatt wind power station there.
