Read the schematic diagram of a weather system below (Figure 3) and answer the questions. Small question 1: Which of the following descriptions of the atmospheric conditions in places A and B is correct A. B place

Small question 1: D

Small question 2: C

Small question 1: According to It can be seen from the question that A is in front of the cold front; B is behind the cold front. Therefore, in order for A to be affected by the cold front, the temperature will decrease and the air pressure will increase. Choose option D.

Quiz 2: According to the characteristics of the front, it can be seen that the airflow flows in a clockwise direction, so this place is in the southern hemisphere. There are two points to note in this question. The first is to judge the wind direction on the isobar line (the horizontal pressure gradient force points from high pressure to low pressure, and the wind direction deviates to the left); the second is to pay attention to the application of the wind vane. Choose item C.
