Fronts near the ground often combine with cyclones to form frontal cyclones.

(1) There is a cold front on the left and a warm front on the right of the cyclone, so the first place is a cold front and the second place is a warm front.

(2) The cold air mass is located behind the cold front and before the warm front, so AD is a cold air mass; BC is a heating group.

(3) A is a cold front, and precipitation should be behind the front; B is a warm front, and precipitation should be in front of it.

(4) According to the rotating direction of the cyclone in the northern hemisphere, it is judged that the A front moves to B and the B front moves to D. ..

(5) The frontal weather system rotates counterclockwise and is located in the northern hemisphere.
