According to the latest weather forecast released by the Central Meteorological Observatory on 20 1,1,2 1, the central and western Guizhou, western Hunan and southern China will be affected by cold and warm air in the next three days.

Question 1:B

Question 2: D.

Test analysis:

Question 1: In combination with the quasi-static front direction in the above figure, the cross section of the quasi-static front is southwest-northeast, and A is wrong; The picture shows that Kunming is located on the side of the heating mass, so it is sunny and B is correct. D error; From the picture below, the terrain of Yunnan-Guizhou Plateau inclines from southwest to northeast, and C is wrong.

Problem 2: Material reflection: When raindrops fall from the air, due to the low temperature near the ground, a thin layer of ice will form on telephone poles, vegetation and roads, which is called "freezing rain" in meteorology. Therefore, combined with the profile of quasi-static front, the top is controlled by warm air mass, and water vapor condenses to form precipitation, while the near surface is controlled by cold air mass, and the temperature is lower than 0℃, resulting in freezing rain, so item D is selected.

Comments: This question is not difficult. The key to solve the problem is to master the graphic information and analyze the information such as air mass distribution, terrain distribution and vertical temperature distribution in the graphic. The answer can be found in materials and charts.
