The picture shown is "A weather system map of a certain area in the mid-latitudes of the Northern Hemisphere". Complete the following questions. (1) The stronger wind force in places A and B is ______. The reason is

(1) The denser the isobars, the greater the horizontal pressure gradient force and the greater the wind force, and vice versa. According to the graph analysis, the isobars at A are densely packed, so the wind force is strong.

(2) According to the way the fronts are represented in the diagram, it is not difficult to judge that the one between A and B is a cold front, and the one between C and D is a warm front.

(3) Cold front precipitation mainly occurs behind and near the front, and the rain area is narrow; while warm front precipitation occurs all in front of the front, and the rain area is wider. According to the information shown in the figure, it can be judged that precipitation may occur at the rear of the cold front and the front of the warm front.

(4) According to the chart analysis, area B will be affected by cold front weather in the next few days. Strong winds, rain, snow, and cooling weather often occur when a cold front passes through. After passing through, a single cold air mass controls the temperature to decrease, the air pressure to increase, and the weather It's sunny.

(5) According to the distribution and value of the isobaric lines in the figure, it is not difficult to judge that D is the low subcenter. The low pressure is also called a cyclone in terms of air flow movement. Since the center is an updraft, it is Rainy weather often occurs under control.

So the answer is:

(1) The isobars of A are denser than those of B

(2) Cold and warm

( 3) Cyclone A and D

(4) Strong winds, rain, snow and cooling. The temperature decreases, the air pressure increases, and the weather becomes sunny

(5) Cyclone D rainy
