Question 3: A.
Test analysis:
Question 1: According to the isobar distance of 2.5 on the map, this is a schematic diagram of the sea level pressure distribution in parts of East Asia on April 20th. Due to the rapid warming of the land, a low pressure is formed, which cuts off the subtropical high and keeps it in the ocean, so the pressure center in the Pacific Ocean is on the high side. The value of isobar from Pyongyang to the east is increasing, so the value of isobar A is1017.5; According to the adjacent isobars, the values can be equal, so the value of isobar A can also be 10 15, so b is correct.
Question 2: According to the picture, Huainan is located in the east of the cyclone, which should be affected by the warm front. From the position of Huainan and the movement of the east line of the low pressure center in the high latitude direction, it can be seen that Huainan should be located in front of the warm front at present and has not been affected by the warm front, but it will bring continuous precipitation in the future, so D is correct.
Question 3: According to the picture, Beijing is currently controlled by high air pressure, and the airflow sinks, which is not conducive to the spread of pollutants. Therefore, the area with the greatest possibility of smog is Beijing, and A is correct.
