The following is the ground weather in some parts of China at a certain moment. Read the little questions. Question1:What is the maximum wind speed in A, B, C and D (

Question 1:B

Question 2: A.

Question 1: Comparing the density of isobars in A, B, C and D, we know that isobars in B are the densest, so the wind speed in B is the highest.

Question 2: A is the center of high pressure in the picture, where downward airflow prevails instead of northwest wind; B is the center of low pressure, with prevailing updraft and rainy weather; C is located in low pressure trough and rainy weather; According to the method of drawing the wind direction, we can know that the northeast wind is blowing in direction D.
