The following figure is a schematic diagram of the weather system affecting China. Look at the picture and answer the next question. Question 1: The picture is a schematic diagram of the weather system, where m is a front with different properties.

Question 1:B

Question 2: A.

Question 1: This question examines frontal cyclones. The front near the ground is often combined with cyclone, which is called frontal cyclone. The left side of the cyclone is a cold front system, and the right side is a warm front system. Therefore, L 1 is a cold front system and L2 is a warm front system. So this question chooses option B.

Question 2: In the next two days, N will be affected by the cold front. In rainy weather, the temperature will drop, but the daily temperature difference will become smaller. So choose option a in this question.
