Causes of continuous rain and snow in western China
First, the reason for the continuous rain and snow:
The western part of China is located in the subtropical high area of the northwest Pacific, and the southwest airflow of the subtropical high area of the northwest Pacific continuously transports the warm and humid airflow of South India to this area, providing it with sufficient water vapor resources. The southward collision of cold air and the northward collision of warm and humid air caused a wide range of rain and snow weather.
Second, the characteristics of continuous rain and snow:
Due to the continuous southward cold air, one of the most remarkable features of autumn rain in western China is its long duration, which may appear in late August and then last until 1 1 month. Nevertheless, due to the adjustment of warm and humid air flow in autumn, precipitation is usually not particularly huge.
Third, the adverse effects of continuous rain and snow:
The shortcomings are mainly manifested in the long duration of autumn rain in West China, which leads to low temperature and great influence on agricultural production, and mature crops are prone to mildew and germination. At the same time, there are many days of autumn rain in West China, and the accumulated rainfall is large, which also easily leads to secondary disasters such as floods and landslides. We can't take it lightly.

In rainy and snowy weather, it is necessary to do a good job in farmland drainage to prevent waterlogging disasters; At the same time, we should pay attention to heat preservation measures to prevent crops from freezing.
5, do a good job in family protection measures
In bad weather, pay attention to the safety of household electricity to avoid electric shock accidents; At the same time, close the doors and windows to prevent wind and rain from invading the room and causing losses.
