Weather system movement

Test analysis:

Looking at the map, judging from the isobar value, the weather system on the map is a ridge of high pressure. Judging from the moving direction and speed, within 30 hours, the ridge of high pressure will pass through place A, then the wind will strengthen, and then the temperature in place A will rise. C right. After the ridge of high pressure, the air pressure will drop and the temperature will rise. A is wrong. The high-voltage system has high power, fast moving speed and stronger wind power. B is wrong. In the high-pressure control area, the weather is mainly sunny, and D is wrong.
