(1) Dongduo Ciel Phantomhive (3 points).

Compared with winter, the temperature near the ground in summer is higher (2 points) and the convection is more vigorous (2 points), which is beneficial to the dilution and diffusion of pollutants in the air (2 points).

Or: Compared with summer, the near-surface temperature in winter is low (2 points) and the atmosphere is relatively stable (2 points), which is not conducive to the dilution and diffusion of pollutants in the air (2 points).

(2) Give priority to the development of public transportation and advocate green travel (2 points); Improve the composition of vehicle energy consumption and reduce vehicle exhaust emissions (2 points); Reasonable urban traffic planning, construction and management, traffic congestion control (2 points).

Test analysis:

(1) The dotted line indicates that the number of haze days is more in winter and less in summer; Compared with the temperature change analysis in the figure, the high temperature near the ground in summer leads to strong airflow convection and pollutant diffusion in the air near the ground; In winter, the temperature near the ground is low and the atmosphere is stable, which is not conducive to the dilution and diffusion of pollutants in the air and is easy to form haze weather.

(2) From the traffic point of view, the smog weather is caused by the dust in the tail gas emitted by cars, so from the traffic point of view, the control of urban smog should first be analyzed from reducing the number of cars, giving priority to the development of public transportation and advocating green travel; From the analysis of reducing automobile exhaust emissions, improve the energy consumption composition of automobiles and use clean energy; Based on the analysis of reducing the driving time of cars, urban traffic planning, construction and management should be carried out reasonably to control traffic congestion.
