How to draw a schematic diagram of a weather system?

How to draw a geographical weather system front? What is the counterclockwise rotation of the Northern Hemisphere?

The Earth's rotation is from west to east. When viewed from the Northern Hemisphere, it rotates counterclockwise. When viewed from the Southern Hemisphere, it rotates clockwise.

Read four different schematic diagrams of weather systems. The arrows represent the direction of air flow, and answer questions 17--18. The schematic diagram representing typhoon weather is (　)A.

A． According to the drawing method of the four pictures, the analysis ① is a cold front, the typhoon is a cyclone with low pressure, so it does not meet the meaning of the question; B. Based on the drawing methods of the four pictures, analyze that ② is a low-pressure system, and the typhoon is a cyclone with low pressure, so it is correct; C. ③ It is a warm front, and the typhoon is a cyclone with low pressure, so it does not meet the meaning of the question; D. ④It is a high-pressure system. Typhoon is a cyclone with low pressure, so it does not meet the meaning of the question. Therefore choose: B.

Read "Schematic diagram of changes in temperature (°C), air pressure (hPa), precipitation (mm), and wind speed (m/s) before and after a weather system passes through a certain city in my country", end

Reading the map, we can see that there was a sharp cooling on the 31st, the wind speed was higher, the temperature reached the lowest, and there was more precipitation. Then, the air pressure increased, the temperature dropped, and the weather turned sunny. Therefore, the weather system was judged to be a cold front, which should be Arrived on the 31st. Therefore choose: B.

This picture is a schematic diagram of the changes in air pressure near the ground in a certain place. Read the picture and combine the knowledge you have learned to complete the question. Question 1: The weather system that controlled this place from 7 to 9 is

Question 1: A Question 2: B This question examines common weather systems. Question 1: The picture shows that when this weather system passes through, the air pressure is extremely low, so it is judged to be a low pressure passing through, possibly under the influence of a tropical cyclone. Question 2: Weather characteristics affected by tropical cyclones: violent storms and rain.

Read the schematic diagram of changes in temperature, air pressure, precipitation, and wind speed before and after a certain weather system passes through Shenyang City, and complete the question. Question 1: The weather system is ( )

Question 1: C Question 2: B Question analysis: Question 1: According to the influence of the weather system shown in the diagram, the temperature will drop and the air pressure will rise. An obvious precipitation process formed, so it was judged to be a cold front passing through. Question 2: According to the increase in air pressure and the decrease in temperature, we can know that this weather is a cold front passing through, and the turning point of temperature and air pressure is on the 31st, so the transit time of this weather system is on the 31st. According to the time when the precipitation appears in the picture, it can also be judged that the weather system arrived in Shenyang on the 31st. So the answer is option B.
