The weather in China on a certain day and at a certain time

Question 1:A?

Question 2:B

Test analysis:

Question 1: On the same isobar graph, the denser the isobar, the greater the horizontal pressure gradient force and the greater the wind force. Comparing the four places in the picture, ① is the densest isobar, which means ① is the place with the strongest wind.

Question 2: Within the dotted line in the figure, isobars are densely distributed and the wind is strong; The message "Topsoil thaws in most areas of the illustrated area, and the surface is dry" in the title indicates that the surface is dry and bare. Combined with the latitude and longitude position in the map, it can be judged that this area is located in the Inner Mongolia Plateau of China, which also shows this feature. Rich and loose ground cover and strong wind, probably sandstorm weather. Item b is correct.
