The figure below is a schematic diagram of a weather system. Look at the picture and answer the following questions. Question 1: What can correctly represent the pressure distribution of the weather system in the following four pictures is

Question 1:C?

Question 2:B

Test analysis:

Question 1: Reading the picture, judging from the slope of the central plane in the picture, the slope is small, it is a warm front, and the warm air mass climbs actively. According to the latitude and longitude in the figure, the weather system is located in the northern hemisphere, and the frontal cyclone converges counterclockwise. Option C, Figures A and D show the high pressure center and anticyclone. Options a and d are wrong. Figure B shows the left side of the frontal cyclone, which is a cold front. Option b is wrong.

Question 2: Reading the diagram of three time periods in the process of air convergence or divergence at PQ, we can see that the distance between isotherms between PQ is decreasing, which means that the temperature difference per unit distance increases and the pressure difference per unit distance also increases, which is a sign of frontogenesis, B right. A, b and c are isotherms. The greater the horizontal distance, the smaller the temperature difference per unit distance. The temperature gradient at T 1 is the smallest, and the temperature gradient at T3 is the largest. A is wrong. The direction of the solid line is the frontogenesis process, and C is wrong. The direction of the dotted line is the previous elimination process, and D is wrong.
