The following figure is a common weather system, and different weather processes are related to the weather system. Read the pictures below and answer the questions. Question 1: Interpretation of the above weather system.

Question 1:B

Question 2: D.

Question 3:B

Test analysis:

Question 1: According to the air pressure distribution and air mass moving direction, Figure A shows the low pressure center; Fig. b shows the high pressure center; C stands for cold front; The d picture shows the warm front.

Question 2: Based on the analysis of the above problems, Figure A shows the low-pressure center control, and if the updraft prevails, it will be rainy; Figure b shows the control of the high pressure center. If downstream prevails, it will be sunny. C stands for cold front, and B is located on the side of the heating mass, and the weather is fine; Figure D shows a warm front, which forms continuous rainfall when crossing the border.

Question 3: In July and August, the summer drought in the Yangtze River basin in China was controlled by subtropical high, which is the weather system in Figure B.

Comments: This question is less difficult. Students can judge the types of weather systems by mastering the distribution of air pressure and the direction of air mass movement, and can analyze the weather characteristics of different weather systems.
