The picture below shows a schematic diagram of the isothermal surface (a surface formed by points with equal temperature values) and isobaric surface on a certain day in a certain area of ??my country. Read the picture to complete questions 3 to 5. Influence of this weather system

A. The information analysis in the figure shows that the air pressure in the middle is high and the temperature is also high, so this air pressure is not caused by thermal reasons, but by dynamic reasons. Therefore, under the influence of this system, the temperature is high, the airflow sinks, there is little precipitation, and the weather is dry. Correct;

B. According to the information analysis in the picture, the air pressure in the middle is high and the temperature is also high, so the air pressure is not caused by thermal reasons, but by dynamic reasons. Therefore, under the influence of this system, the temperature is high, so it does not meet the meaning of the question;

C. The information analysis in the figure shows that the air pressure in the middle is high and the temperature is also high, so this air pressure is not caused by thermal reasons, but by dynamic reasons. Therefore, under the influence of this system, the temperature is high, the airflow sinks, there is little precipitation, and the weather is dry. Does not meet the meaning of the question;

D. The information analysis in the figure shows that the air pressure in the middle is high and the temperature is also high, so this air pressure is not caused by thermal reasons, but by dynamic reasons. Therefore, under the influence of this system, the temperature is high, the airflow sinks, there is little precipitation, and the weather is dry. Doesn't fit the meaning of the question.

So choose: A.
