How is the cold front formed?
when the cold air mass actively moves towards the warm air mass, the front edge of the heavier cold air mass is inserted under the warm air mass, so that the warm air mass is forced to rise. The warm air mass cools in the process of lifting, and the water vapor in it is easy to condense into clouds and rain. If the warm air contains a lot of water vapor, it may bring rain and snow. The cold front moves faster and often brings strong winds. Therefore, when the cold front crosses the border, it is prone to cloudy, rainy, windy and cooling weather phenomena. After the cold front crossed the border, the cold air mass replaced the original warm air mass, so the temperature and humidity plummeted, the air pressure rose and the weather turned fine. Cold front exists all year round in China, especially in winter.
