Read the schematic diagram of four different weather systems in a place before and after crossing the border and complete the following questions. Question 1: The judgments of the four weather systems are correct.

Question 1:C?

Question 2:B

Test analysis:

Question 1: There are four common weather systems: warm front, cold front, cyclone and anticyclone. As can be seen from the figure, the low pressure in center A is a cyclone, the high pressure in center B is an anticyclone, the low pressure before transit in C is a cold front, and the high pressure before transit in D is a warm front. C right.

Question 2: The warm front forms continuous precipitation, and the cold front forms four weather systems, such as summer rainstorm, cold wave and sandstorm in the north. Cyclones bring abundant precipitation (frontal cyclones can also form), and anticyclones descend to form drought. B is right.
