What's the difference between cold and warm fronts?

The differences in cold and warm fronts are as follows:

1, different front slopes

In the cold front, the cold air mass is strong, which pushes the front to move quickly, and the warm air mass on it rises sharply, but the slope of the front is large. In the warm front, the warm air mass climbs slowly above the cold air mass, which pushes the front to move slowly, so the slope of the front is small.

2. The weather changed differently when it appeared.

When a cold front crosses the border, there are often strong winds, cloudy weather, rain, snow and other weather. After crossing the border, the temperature dropped, the air pressure rose, and the weather turned fine, that is, as the saying goes, "an autumn rain and a cold." When a warm front crosses the border, there is often continuous precipitation. After crossing the border, the position of the cold air mass was replaced by the warm air mass, the temperature rose, the air pressure dropped, and the weather turned cloudy, that is, as the saying goes, "a spring rain and a warmth."

3. Different characteristics

Cold front is characterized by fast moving speed, high intensity and short duration. The precipitation is behind the front and the precipitation area is relatively narrow. Warm front is characterized by slow moving speed, low intensity and long duration. Precipitation is in front of the front, and the precipitation area is relatively wide.

4. The symbols are different.

The cold front is a β triangle arrow pointing in the direction of the cold air mass, and the warm front is a в semicircle arrow pointing in the direction of the warm air mass.
