(3) once in winter (2 points)

(4)C？ Differences in thermal properties between land and sea (2 points)

(5) Dorsey north wind (or northerly wind)? Topographic precipitation (3 points)

Problem analysis: Problem (1) According to the distribution of air pressure, it can be known that the air pressure at A is called low pressure, the air pressure at B is high pressure, and its airflow movement is anticyclone. Question (2) According to the direction of pressure gradient force and geostrophic deflection force, it can be judged that the geostrophic wind direction is southerly; Affected by this, the temperature is high and the air pressure is low; According to the sign of the front, we can know that it may be affected by the cold front in the next few days, which is characterized by rain, snow and strong winds. Question (3) At this time, a high pressure is formed on the land, and it may be winter in the northern hemisphere. The first isobar is dense, with strong pressure gradient and strong wind force. Question (4) Our hometown belongs to temperate monsoon climate. From the distribution of temperature and precipitation, Figure C is cold and dry in winter and hot and rainy in summer, belonging to temperate monsoon climate; It is formed by the difference of thermal properties between land and sea. Question (5) Northwest wind prevails in winter, and Station C is located under the influence of northwest wind from the ocean, mostly in topographic precipitation. Question (6) Figure 20 is a top view, obtained by remote sensing technology.

Comments: This topic examines the judgment of weather system, the description of weather characteristics, the judgment of climate type and the comparison of wind strength based on the pressure distribution map. The difficulty of the exam is moderate. The key to solve the problem is to judge the weather system according to the distribution of isobars, remember the characteristics of the weather system, and master the distribution of climate types and the judgment method of wind power.
