Read the simplified diagram (picture) of the near-surface weather situation in a certain area and answer the following questions. (1) Among the three places A, B, and C, the one with the highest air pressure is ______. (2)

(1) According to the graph analysis, the air pressure of A is 1020, the air pressure of B is between 1015-1020, and the air pressure of C is between 1000-1005, so the air pressure of A is the highest.

(2) According to the drawing method of wind direction, it is not difficult to draw that the wind direction in A is northwest.

(3) Before the cold front passes through, the temperature is high, the air pressure is low, and the weather is sunny. Strong winds, rain, snow, and cooling weather often occur when it passes through. After the cold front passes through, the temperature drops, the air pressure increases, and the weather turns sunny.

So the answer is:

(1) A?

(2) Northwest wind (or northerly wind)

(3 ) Strong wind, rain and snow, the temperature drops? The air pressure rises
