How to judge cold and warm fronts?

How to judge the cold and warm front: according to the symbols representing the cold and warm front; According to the moving direction of the cold air; According to the direction of the rain; According to the angle between the peak surface and the ground.

Expand knowledge:

The front is generally divided into cold and warm fronts. Cold front refers to the wind in which the cold air mass actively moves to the warm air mass. The front edge of the cold air mass is inserted under the warm air mass, forcing the warm air mass to rise. The warm air mass cools in the process of lifting, and the water vapor in it can easily condense into clouds and rain. Therefore, when the cold front crosses the border, it is prone to rainy and windy weather.

After the cold front crossed the border, the cold air mass replaced the original warm air mass, so the air pressure increased, the temperature and humidity plummeted, and the weather turned fine.

Warm front refers to the wind that the warm air mass moves to the cold air mass actively. The warm air mass climbs slowly along the cold air mass, and the water vapor cools and condenses to produce clouds and rain. Warm front precipitation mostly occurs before the front, mostly continuous precipitation. After the warm front crossed the border, the warm air mass occupied the position of the original cold air mass, so the temperature rose, the air pressure dropped and the weather turned fine.

Most precipitation and some disastrous weather in China are related to the front. The front that affects the weather in China is mainly the cold front. The summer rainstorm in northern China is mostly frontal rain formed by cold front. The cold wave that broke out in winter in China was formed when the cold front went south.

The difference between cold and warm fronts:

The intensity of cold and warm air masses in cold and warm fronts is different, so the front type and direction are also different. The cold front is the front where the cold air mass actively moves to the warm air mass. In the picture, the part of the cold air mass generally depicts the direction arrow of the cold air mass moving forward, which is opposite to the direction of the airflow arrow of the warm air mass forced to rise on the front.

A cold front is the front of cold air. At the intersection of cold and warm air, cold air pushes towards warm air. It is windy and rainy on the cold front, and windy and cool after the front.

The warm front is the front where the warm air mass actively moves to the cold air mass. In the figure, the airflow direction arrow of the warm air mass climbing along the front is consistent with the movement direction of the cold air mass on the other side of the front. Warm front, rainy weather before the front, cloudy and sunny after the front, and the temperature rises.
