Question 1: cyclone (low pressure) (2 points)

Question 2: Gale (gale) and rainstorm (rainstorm) (2 points)

Question 3: Eastern coastal areas (2 points)

Question 4: As shown in the figure (each wind direction 1, ***4).

Test analysis:

Question 1: According to the analysis of airflow movement characteristics in the figure, the weather system described in the figure is cyclone or low pressure.

Question 2: Judging from the cyclone in the picture, the cyclone may form a typhoon, so the main weather characteristics of the weather system are strong winds and heavy rains.

Question 3: Judging from the cyclones in the picture, cyclones may form typhoons, so the areas where weather systems occur are mostly in the eastern coastal areas of China.

Question 4: The plan of the cyclone in the northern hemisphere converges counterclockwise to the center.

Comments: Understand the characteristics of low-pressure and high-pressure systems and their impact on the weather.

Cyclone and anticyclone describe the airflow condition of weather system, and low pressure and high pressure describe the pressure condition of weather system.

In fact, cyclone is a low-pressure system and anticyclone is a high-pressure system.
