The figure below is a sketch of the ground weather at a certain time in an area. Read the picture and complete the following questions. Question 1: The wind direction in C is () A. Northeast B. East.

Question 1:C?

question 2:D?

Question 3:D

Question analysis:

Question 1: The wind direction is always perpendicular to the isobar from the high-pressure area to the low-pressure area, with the northern hemisphere leaning to the right and the southern hemisphere leaning to the left. According to the numerical analysis of isobar in the figure, the wind in C is northwest wind, and C is right. A, b and d are wrong.

Question 2: In the frontal cyclone weather system, there is a cold front on the left and a warm front on the right. According to the map analysis, area A is located on the left and area B is located on the right, so the corresponding weather systems are cold front, warm front and D pair respectively. An anticyclone can't bring precipitation weather. A, B and C are wrong.

Question 3: According to the characteristics of each weather system, the temperature in the control area of the high-pressure center is low and the air pressure is high. The temperature in the low-pressure central control area is high and the air pressure is low. So the temperature in A and B is low. A and b are wrong. C is located on the cold air mass side of the cold front, with low temperature and C is wrong. Dingdi is located on the side of the warm front, with high temperature, D right.
