According to the statistical data of the weather changes in Nantong in the days around May 5 in Figure 7 on the right, answer the question: Question 1: This weather change process is most likely caused by (

Question 1:C

Question 2: D.

Question 3:B

Test analysis:

Question 1: It means that the weather system transits, the temperature drops, the air pressure rises, and rainy weather appears, so it is judged as cold front weather.

Question 2: The cold front precipitation is because the cold air mass actively attacks the warm air mass, and the warm air mass is forced to rise. During the rising process, the temperature drops and the water vapor condenses to form precipitation.

Question 3: Meiyu in the middle and lower reaches of the Yangtze River is formed by quasi-static front; Winter cold wave is affected by cold front; Typhoon belongs to the influence of tropical cyclone; Summer drought is due to the influence of subtropical high.

Comments: This question is less difficult. Students only need to master the temperature and pressure changes in the chart, and combine the weather characteristics of different weather systems to analyze the main weather systems formed by common typical weather. For this kind of questions, students should strengthen the implementation of the basic knowledge of textbooks.
