The picture is a simplified map of the surface weather in a certain area at a certain time. Read the pictures and complete the questions. Small question 1: The wind direction at place C in the picture is A. Northeast B. Southeast c. northwest

Small question 1: C

Small question 2: D

Test question analysis:

Small question 2:D p>

Quiz 1: From the longitude and latitude in the picture, we can judge that the area is located in my country. Specifically, the wind direction should flow from high pressure to low pressure, and then deflect to the right according to the northern hemisphere. The wind direction in C is northwest.

Quiz 2: The weather systems in areas A and B shown in the figure are frontal cyclones, and the northern hemisphere converges counterclockwise from all sides to the center. Area A is behind the cold front, area B is before the warm front, and the shaded area in the figure indicates the range of rain. The strength of the wind depends on the density of the isobars. The wind force in Ding is smaller than that in C. The Eurasian continent is high pressure. In the winter of the northern hemisphere, A, B and C are controlled by cold air masses, while Ding is affected by warm air masses and has the highest temperature.

Comments: This question is of moderate difficulty. Use the isobars map of a certain area as material to test students' knowledge of wind direction, frontal cyclones, etc.
