This picture is a weather system picture. Question 1: The weather system described in this picture is (2 points). Question 2: The main weather characteristics of this weather system are (2

Small question 1: Cyclone (low pressure) (2 points)

Small question 2: Squally wind (strong wind), heavy rain (heavy rain) (2 points)

Small question 3: Eastern coastal area (2 points)

Small question 4: As shown in the picture (1 point for each wind direction, ***4 points)

Test question analysis:

Small question 1: Analysis based on the air flow characteristics in the picture: The weather system described in this picture is a cyclone or low pressure.

Quick question 2: Based on the picture, it is judged that it is a cyclone: ​​the cyclone may form a typhoon, so the main weather characteristics of this weather system are strong winds and heavy rain.

Quiz 3: Judgment based on the picture that it is a cyclone: ​​Cyclones may form typhoons, so the areas where this weather system occurs are mostly in the eastern coastal areas of my country.

Quiz 4: The plane diagram of cyclones in the Northern Hemisphere shows counterclockwise convergence toward the center.

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

Cyclones and anticyclones describe the airflow conditions of weather systems, while low pressure and high pressure describe the pressure conditions of weather systems.

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