The following is a schematic diagram of the weather system on a certain day in summer in China.

The standard answer, the topic seems simple, but it is not.

First question

If it is summer in our country, then 990 hectopascals in A place should be at or near the low pressure center in the ground map, while 10 10 hectopascals in B place are low pressure periphery, and the warm front points to D place, so the system is a warm and humid low pressure system rather than a high pressure system. It can be determined that the arc of the isobar points to B.

(1) the answer is a.

Because this system is obviously a low-pressure system and a cyclone, the wind along the edge of the isobar rotates counterclockwise, so the wind in area C should be southwest wind or southerly wind.

The answer is B.

Guaranteed to be right!
