The cold air is going south. What impact will it bring?

The influence of cold air going south is described as follows:

First, the temperature drops and the weather turns cold:

The cold air from the south will bring a lower temperature, which will lead to a drop in temperature and cool weather. The influence of this cold air usually lasts for a few days to a week, especially in winter or early spring, which will bring obvious cold weather.

Second, the rainfall increased:

Cold air heading south is often accompanied by strong airflow and unstable weather conditions, which will lead to an increase in rainfall. Under the influence of cold air, when cold air meets warm and humid air, it will produce obvious convective clouds, which will lead to precipitation.

Third, the wind increases:

When cold air goes south, the wind will generally increase due to the hedge of cold and warm air. The cold wind of cold air will form a wind gradient with the hot wind of warm air, which will increase the wind speed and make the wind stronger. Especially in mountainous areas or coastal areas, cold air will be affected by factors such as topography or land-sea intersection, and the wind will increase, forming a strong storm.

Four, affect the weather circulation:

The southward movement of cold air is one of the changes in the atmospheric circulation system. Cold air masses from high latitudes are transported into low latitudes by airflow. The process of cold air going south will affect the original meteorological factors such as pressure field, wind direction and wind speed, and then change the weather circulation. The arrival of cold air may bring about sudden changes in the weather, thus affecting the weather forecast and weather change forecast.

The influence of verb (abbreviation of verb) on ecological environment;

Cold air going south will cause the temperature to drop, which will have a certain impact on the growth and reproduction of animals and plants. Some plants may be damaged by cold, especially in early winter or late spring. For crops, cold air going south may have a certain impact on planting, so it is necessary to take protective measures to reduce losses.

Sixth, expand knowledge:

Cold air refers to a relatively cold air mass, usually from high latitudes. As the airflow moves to low latitudes, it brings low temperature and cold weather. Cold air heading south is a part of the atmospheric circulation system, which is usually accompanied by the intersection of cold front and cold and warm air. Cold front is the front where cold air meets warm air, which is often accompanied by precipitation and weather changes.
