The Meteorological Observatory of Shenyang Meteorological Center issued the red warning of the highest fog level to Dalian, Panjin and Yingkou in the early morning of June165438+1October 4, 2008.

Question 1:D

Question 2:B

Test analysis:

Question 1: The reason why there is fog in Liaoning and other areas in late autumn is that the temperature difference between day and night is large, and water vapor is easy to condense. There are many sunny days in this season, which is conducive to the generation of floating dust.

Question 2: The fog appeared in the early morning of June165438+1October 14, 2008, and the duration was not too long, so the direct point of the sun was directly in the southern hemisphere and moved south.

Comments: This question is moderately difficult. Students are required to master the causes of late autumn fog and the seasonal movement of direct sunlight.
