The picture below is a map of the distribution of sea surface pressure and related weather systems in a certain area. Read the picture and answer the following questions (1) The weather systems in the picture mostly appear in

(1) January? North (northwest)? Cold and dry? Southwest wind (4 points)

(2) A? D (2) points)?

(3) Sunny? Beijing is controlled by a high-pressure ridge, and downdrafts prevail. Water vapor in the air is difficult to condense into clouds and cause rain (3 points)

(4) Southwest? Northwest (2 points)

(5) Against the wind and against the current (2 points)

Test question analysis:

(1) According to longitude and latitude Interpretation: At this time, a high pressure center forms over the land in the Northern Hemisphere, so the weather systems in the picture mostly appear around January. At this time, the prevailing wind in most parts of my country is northwest wind. The weather in the north is characterized by cold and dry weather, and Rome is dominated by southwesterly winds at this time.

(2) According to the frontal cyclone weather on the right, the cold front rainfall is located behind the front. At this time, there are four places A, B, C, and D. The most likely places for precipitation are A and D.

(3) At this time, Beijing is controlled by a high-pressure ridge and has sunny weather. The reason is that Beijing is controlled by a high-pressure ridge and downdrafts prevail, so water vapor in the air cannot easily condense into clouds and cause rain.

(4) According to the interpretation method of wind direction, first determine the direction of the horizontal pressure gradient force, and then combine it with the geostrophic deflection force to the right. Therefore, at this time, the southwest wind blows in place C and the northwest wind blows in place A. .

(5) The northeast monsoon prevails in the North Indian Ocean in winter. Under the influence of this monsoon, the ocean currents rotate counterclockwise. An oil tanker from the Persian Gulf to Hong Kong is sailing in the North Indian Ocean at this time, and its course is the same as that of the North Indian Ocean. The relationship between prevailing wind direction and ocean current direction is headwind and against current.

Comments: This question tests many knowledge points and requires careful judgment based on the knowledge you have learned. This question locates the location of the air pressure center based on longitude and latitude, then determines the air pressure condition, determines the season, and then solves the problem.
