Influence of Asian low pressure on climate

In summer, a thermal low pressure center appeared in the Asian continent, which cut off the subtropical high pressure area, and the subtropical high pressure area remained in the ocean, changing from a belt distribution to a high pressure center.

Due to the influence of the Asian depression (also known as the Indian depression), the wind blows from the ocean to the land. In summer, the southeast monsoon prevails in China, and typhoons, strong winds and heavy rains form along the southeast coast.

The moist air flow brought by the southeast monsoon from the sea began to land in China at the end of April, reached the middle and lower reaches of the Yangtze River in May and June, reached North China in July and August, and reached Northeast China in September. The Asian high began to appear in 65438+ 10, and the rain belt quickly withdrew southward. Where the moist airflow (or rain belt) brought by the southeast monsoon from the sea stops, there will be heavy rain, but once it leaves this place, it will dry up after a long time. This caused the instability of monsoon in China, and the change of precipitation season led to the flood disaster in China.

Winter is not as low as that in Asia, but only as high as that in Mongolia. Therefore, the northwest monsoon prevails in China. Because the wind blows from the land to the sea, the airflow is dry, and there is a general lack of precipitation in China. Most areas are dry and there is little precipitation.

I sorted out and typed all the summaries made by our teacher. Do you think it's clear enough?
