What weather will the cold front bring after crossing the border?

When a cold front crosses the border, there are usually windy, rainy and other weather conditions. After the cold front crossed the border, the cold air mass controlled the area, and the weather turned fine in autumn and winter. We often hear "cold front crossing the border ..." in the weather forecast. What is a cold front? According to experts from the Provincial Meteorological Observatory, the interface formed by different cold and warm air masses is commonly known as "front". Near the front is the intersection of cold and warm air, so the meteorological elements here change dramatically, often accompanied by clouds, precipitation, thunderstorms, strong winds and other weather phenomena. In the process of moving, the cold air mass plays a leading role, and the front that pushes the front to move to the side of the warm air mass is called the cold front.

The frequency of cold front crossing is the most frequent in winter. Generally, the cold front moves from south to southeast (for example, the cold front in Inner Mongolia passes through our province and slowly presses south from northwest to southeast).

Before the influence of cold front, southeast wind or southwest wind usually blows, and the air pressure decreases, the humidity increases and the temperature is higher; Affected by the cold front, the wind turns north, the air pressure gradually increases, the humidity decreases, the temperature drops, and precipitation generally occurs; After the cold front, cold air gradually occupied the area originally controlled by warm air, and the temperature dropped, the air pressure rose and the weather turned fine.
