(10) This map is a schematic diagram of some geographical elements of a city in eastern China. Look at the picture and answer the following questions. (1) Figure A is the most cloudy.

(1) ① July is summer in China, and there is a lot of rain, which takes away suspended particles; ② Plants are dense in summer, and smoking has a strong dust retention effect; (3) Residents burning coal in winter increases suspended particles in the atmosphere; ④ Strong winds in winter frequently bring dust to the south: ⑤ Cold front weather in winter may cause inversion, and turbidity is not easy to spread. (2 points for every point, 3.6 points for correct answer)

(2)B(2 points)? C(2 points)

Test analysis:

(1) Figure A shows that the most cloudy month is 65438+February, and the least month is July. The reasons for the above characteristics are as follows: ① July is the summer in China, and there is more rain, which takes away suspended particles; ② Plants are dense in summer, and smoking has a strong dust retention effect; (3) Residents burning coal in winter increases suspended particles in the atmosphere; ④ Strong winds in winter frequently bring dust to the south: ⑤ Cold front weather in winter may cause inversion, and turbidity is not easy to spread.

(2) The pollution of observation station A is serious, followed by observation station B, and observation station C is the lightest. From the rose diagram of wind direction, if A, B and C in Figure B are the distribution positions of three monitoring stations A, B and C in Figure A, and the wind frequency in this area is as shown in Figure C, then the reasonable matching is: monitoring station A and monitoring station B.
