Question 1:D

Question 2: A.

This topic examines the judgment of weather system and the interpretation of topographic map.

Problem1:The isoline of the earth's rotation linear velocity on the xy line shows that it bends at the mountain range, indicating that the bending direction should be the direction with smaller earth rotation linear velocity. Therefore, it is concluded that the area is located in the southern hemisphere and PQ is the front, so it is known that there is a low pressure center, PQ line is a trough of low pressure, and the west side of low pressure should be a cold front. The precipitation of the cold front is behind the front, combined with the beacon, so the rain area is located in the southeast of PQ, so the D option is correct.

Question 2: The farther away from the mountain range, the smaller the linear velocity, so it can be concluded that the east side of the mountain range is higher in the west and lower in the east. Option A is correct.
