This picture shows the ground weather in some parts of China for one month. Read the map and answer the following questions. (8 points) (1) This chart is most likely to be _ _ _ _ _ _ month (1 or

Question 1: 1 month (1'); Anticyclone (1'); Rising (1')

Question 2: Warm front (1')

Cloudy, windy, rainy (snowy), cooling (1')

Air pressure increases, air temperature decreases, humidity decreases, and the weather turns fine (1').

Question 3:C (1')?

Question 4: northerly wind (northwest wind) (1')

Test analysis:

Question 1: The picture shows that Eurasia is controlled by high pressure, so it is judged as winter in the northern hemisphere. As shown in the figure, the air pressure in center A is higher than that in the surrounding area, so it is judged as a high-pressure center, and it is judged as an anticyclone according to the airflow situation. The air pressure in the center of B is lower than the surrounding area, so it is judged as low pressure (cyclone), and updraft prevails in the vertical direction.

Question 2: There is a warm front near E, which is about to move to E, and the cold front at C is about to cross the border, and there will be cloudy, windy, rainy and cooling weather. After the cold front crossed the border, controlled by the cold air mass, the temperature dropped, the air pressure rose and the weather turned fine.

Question 3: The warm front attacks the warm air mass actively, and the cold front attacks the cold air mass actively, so the warm air mass is forced to rise.

Question 4: According to the air pressure distribution in the figure, the horizontal air pressure gradient force is perpendicular to the isobar and points from high pressure to low pressure. The geostrophic bias is inclined to the right in the northern hemisphere, and the wind direction is inclined to cross the isobar, so just draw the wind direction of M.

Comments: This question is not difficult and belongs to the basic test. Students should strengthen the implementation of basic knowledge points in their usual study. The key to solve the problem is to be able to judge the front nature, weather change characteristics, wind direction and other contents from the isobar distribution shown in the figure.
