Read the "Weather system map of some areas in my country at a certain time in spring" and answer the following questions: (1) In the two places A and B in the map, ______ is the high pressure center, by day

(1) A in the picture is a high-pressure center, which is classified as an anticyclone according to the airflow conditions of the weather system. B in the picture is a cyclone, and the airflow in the center of B is rising in the vertical direction.

(2) The weather in A is sunny under the control of the anticyclone, and the weather in B is cloudy and rainy under the control of the cyclone. In the area controlled by the two pressure centers of A and B, the diurnal temperature range is larger in A.

(3) In the horizontal direction of the Northern Hemisphere cyclone, the airflow flows counterclockwise from the surroundings to the center. Among the two fronts ① and 2 in the figure, the cold front is ① and the warm front is ②. There are rainy weather before the warm front and after the cold front.

(4) In the two cities in the picture, Harbin is controlled by a single cold air mass, and Changchun is controlled by a single warm air mass. The temperature in the two cities in the picture is higher in Changchun; specifically, the wind direction is from high pressure to low pressure. The northern hemisphere deflects to the right, and southerly winds form in Changchun.

So the answer is:

(1) Anticyclone A? Rising

(2) A

(3)①②Back and forward

(4) South of Changchun
