Abcd weather

A, in the figure, the air pressure at A is lower than that at C, A is at high altitude, and C is close to the ground. The temperature at a is lower than that at c, so it doesn't meet the question;

B, in the figure, the air pressure at C is higher than that at A, because the temperature near the ground at C is low, the gas contracts and sinks, and the airflow flows from A to C, which does not meet the question;

C and B in the picture are high pressure, and D is low pressure, because D near the ground is heated and expanded, and the airflow flows from D to B, so it does not meet the question;

D, because C is high pressure, D is low pressure, because the temperature near the ground C is low, the gas contracts and sinks, and it is sunny; Near the ground D, it is heated and expanded, and it rains continuously. So, it is correct.
