Read the graphic materials and answer the following questions. Material 1 The picture is "A simplified picture of the weather situation near the ground on a certain day". The picture is a satellite cloud image of my country taken on that day. material

(1) Low-pressure anticyclone (2 points)

(2) Southerly wind? Higher, lower,? Cold front (1 each points, ***4 points)? Rain, snow, strong wind, cooling, etc. (2 points)

(3) Winter? A (2 points)

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

(5) How much northwest wind (or northerly wind) orographic rain (3 points)

(6) Remote sensing (1 point) < /p>

Test question analysis: In question (1), according to the air pressure distribution, it can be seen that the air pressure at A is called low pressure, and B is high pressure, and the movement of the air flow is an anticyclone. Question (2) According to the direction of the pressure gradient force and the geostrophic deflection force, it can be judged that the wind direction in Dingdi is southerly. Affected by this, the temperature is high and the air pressure is low. According to the sign of the front, it can be known that there may be a cold front in the next few days. Affected by this, its weather characteristics are rain, snow, strong wind, cooling, etc. Question (3) At this time, high pressure is formed over the land. It may be winter in the Northern Hemisphere. The isobars at A are densely packed, the pressure gradient is strong, and the wind is strong. Question (4) Our hometown has a temperate monsoon climate. Reading the temperature and precipitation distribution, we can see that: Figure C is cold and dry in winter, and hot and rainy in summer. It belongs to a temperate monsoon climate; it is formed due to the difference in thermal properties of sea and land. Question (5) The northwest wind prevails in winter. Site C is affected by the northwest wind from the ocean and rains frequently. Question (6) Figure 20 is a high-altitude bird's eye view, obtained using remote sensing technology.

Comment: This question combines the pressure distribution chart to test the judgment of weather systems, description of weather characteristics, judgment of climate types and comparison of wind strength. The difficulty of the test is medium. The key to solving the problem is to use isobars. Judge weather systems by distribution, recognize the characteristics of weather systems, and master the distribution of climate types and methods of judging wind strength.
