A high school geography problem (about the weather), ask for help.

The first question c, March should be the front rain formed by the warm and humid airflow in the south, and it is a warm front system.

The second question a, the first question is already the warm front system, and the second question is of course the frontal rain. Convective rain means that water vapor condenses into rain at high altitude due to the rise of ground temperature and air. The equatorial region is basically convective rain.

The third question D and A should be negatively correlated. The higher the temperature, the lower the relative humidity.

B it should be a warm front crossing the border. Needless to say,

C, 2 1 is sunny, with few clouds and relatively weak atmospheric inverse radiation, and 20 is rainy, with thick clouds and strong atmospheric inverse radiation, so C is wrong.

E, if it is sunny, the air pressure should be low.

F just corresponds to C, which is also wrong.
