How to judge where the weather (precipitation) is on both sides of the cold and warm front?

The cold front is the precipitation before the front, and the warm front is the precipitation after the front.

The cold front is that the cold air mass actively moves to the warm air mass and lifts the warm air mass. During the uplift process, water vapor condenses in front of the front to form precipitation.

Warm front means that the warm air mass moves to the cold air mass actively and climbs on it. During the climbing process, water vapor condenses behind the front to form precipitation.

Cold and warm fronts will bring rainy weather, cold front will bring short-term rainstorm, and warm wind will bring continuous rainy weather.

It is strongly recommended that the landlord look at the picture and understand it best.
