The picture below is a distribution map of air pressure conditions at a certain time on a certain day in November. Read the picture and answer the following questions. Question 1: The following statements about the weather characteristics of Xi'an on that day are incorrect

Small question 1: C

Small question 2: D

Test question analysis:

Small question 2:D p>

Quick Question 1: In the picture, Xi'an is located in the center of high pressure, the air flow sinks, and the weather is mainly sunny; there are few clouds on sunny days, the atmosphere weakens solar radiation less during the day, and the temperature is high. At night, the atmospheric reverse radiation is weak, and the temperature is low, so the temperature difference between day and night is large; and this season is winter, the weather is clear, and the atmospheric insulation effect is poor, so frost may occur at night. So choose C.

Quiz 2: The weather system A in the picture is a cold front. Under its influence, precipitation and cooling may occur in Urumqi, but there will not be continuous precipitation; the isobars in the next three days will change from sparse to Dense, so the wind speed changes greatly and increases; from the analysis of the isobaric line distribution in the figure, the wind direction will change from southerly to northerly. So choose D.
