This picture is a schematic diagram of the ground weather in a certain area at a certain time. Look at the picture and answer the questions. Question 1: The wind direction of M in the picture is A. No
Question 1:C
Question 2: A.
Test analysis:
Question 1: From the distribution of the high pressure center in the figure, the horizontal pressure gradient force is perpendicular to the isobar, pointing from high pressure to low pressure, while the geostrophic force in the northern hemisphere is to the right, so the wind direction can be drawn as northwest wind.
Question 2: According to the trough of low pressure in the picture, it is judged that the rain area is near the trough of low pressure, so it is judged as frontal rain. Combined with the latitude and longitude position and the distribution of weather system, it is judged that the cold high pressure formed in the Eurasian continent is strong and the front of the cold high pressure is cold front.
Comments: The key to solve this problem is to master the judgment of wind direction on isobar chart and the judgment of graphic weather system.
