Why is it warm front continuous precipitation and cold front array precipitation?

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; On the contrary, it is a warm front, the front is rainy, and it turns cloudy and sunny after the front, and the temperature rises.

The front formed by the active movement of cold air mass to warm air mass is called cold front. The cold air behind the front moves much faster than the warm air mass, affecting the warm air mass and forcing it to rise strongly. The cold front moves faster than the warm front, moving at a speed of 25 to 30 miles per hour. However, the moving speed of the extreme cold front is recorded as 60 miles per hour. So the formation of stratum sedimentation.

Not a cold front. The warm front moves slower than the cold front, which may cause continuous precipitation or fog. Basic characteristics: low intensity, wide range and long time, often appearing in temperate zone.
