The cold front rainfall is behind the front, and the warm front rainfall is before the front. What do you think of the front and the back?

After judging the cold and warm fronts and other fronts, we can see the symbols on the weather map and the moving direction of the air mass:

(1) On the weather map, the cold front is represented by a triangle, and the direction pointed by the triangle arrow is the front; The warm front is represented by a semicircle, which refers to the front of the warm front.

(2) The cold front moves to the side of the warm air mass, and the front is on the side of the warm air mass; The side moving to the cold air mass is a warm front, and the side of the cold air mass is a front.

So the answer is:

(1) Judging from the legend

On the weather map, the cold front is represented by a triangle, and the direction pointed by the triangle arrow is the front; The warm front is represented by a semicircle, which refers to the front of the warm front.

(2) Judging from the direction of motion

The side moving to the warm air mass is a cold front, and the side of the warm air mass is a front; The side moving to the cold air mass is a warm front, and the side of the cold air mass is a front.
