The picture below is a schematic diagram of airflow movement in a certain area of China. Read the picture and answer the following questions. (1 points) (1) Please name the graphic weather system and explain the judgment.

(1) Frontal cyclone (1 point)? Basis: the airflow rotates counterclockwise to the center and forms two fronts on the east and west sides. (2 points)

(2) The first airflow is cold airflow, and the second airflow is warm airflow. Reason: air flow blows from north to south, and air flow is the other way around. (2 points)

(3) M is a cold front, the rain area is behind the front, n is a warm front, and the rain area is in front of the front. (3 points)

(4) When cold and warm air meet, due to the difference in nature, the warm and light airflow climbs above the cold and heavy airflow, and the temperature of the warm airflow drops during the rising process, and the water vapor reaches supersaturation and condenses to form precipitation. (2 points)

(1) According to the diagram, the airflow rotates counterclockwise to the center and forms two fronts on the east and west sides. Frontal and cyclone are often combined to form frontal cyclone.

(2) judging from the rotating direction of the cyclone in the figure, the cyclone is located in the northern hemisphere, so the airflow blows from north to south as a cold airflow; The second airflow blows from south to north, which is warm air flow.

(3) According to the diagram, the curve M is located on the left side of the cyclone and the curve N is located on the right side of the cyclone, so M is a cold front, the rain area is behind the front, N is a warm front, and the rain area is in front of the front.

(4)M and N are both frontal systems, and the reason for precipitation in frontal systems is that cold and warm air meet, and due to the difference in properties, warm and light air flows climb above cold and heavy air flows, and the temperature of warm air flows drops in the rising process, and water vapor reaches supersaturation and condenses to form precipitation.
