How to draw a schematic diagram of weather system?

How to draw the front of the geographical weather system? What is the counterclockwise rotation in the northern hemisphere?

The earth rotates from west to east, counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.

Read the schematic diagram of four different weather systems. The arrow represents the direction of air flow. Answer the question 17- 18. The schematic diagram representing typhoon weather is () A.

A. According to the drawing method of the four pictures, ① it is a cold front, and the typhoon is a low-pressure cyclone, which does not meet the meaning of the question; B. According to the drawing method of four pictures, it is correct to analyze that ② is a low-pressure system, typhoon is a cyclone and low pressure; C.③ It is a warm front, and the typhoon is a low-pressure cyclone, which does not meet the meaning of the question; D.④ is a high-voltage system. Typhoon is a low-pressure cyclone, which does not meet the meaning of the question. Therefore, it was chosen as B.

Read "Diagram of temperature (℃), pressure (hPa), precipitation (mm) and wind speed (m/s) before and after a weather system passes through a city in China".

Looking at the map, we can see that the temperature dropped suddenly on 3 1, the wind speed was high, the temperature reached the lowest, and there was more precipitation. Then, the air pressure rises, the temperature drops and the weather turns fine. Therefore, judging that the weather system is a cold front, it should arrive at 3 1 Therefore, it was chosen as B.

This picture is a schematic diagram of the change of air pressure near the ground in a certain place. Look at the pictures and complete the questions according to what you have learned. Question1:What was the weather system that controlled this area on July 9th?

Question 1:A Question 2:B This question examines common weather systems. Question 1: When the weather system transits, the air pressure is extremely low, so it is judged as a low-pressure transit, which may be caused by a tropical cyclone. Question 2: Weather characteristics affected by tropical cyclones: violent storms.

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

Question 1:C question 2:B question analysis: question 1: affected by the weather system, the temperature dropped and the air pressure rose, forming an obvious precipitation process, so it was judged as a cold front crossing. Question 2: According to the increase of air pressure and the decrease of temperature, we can know that this weather is a cold front transit, and the turning point of temperature and air pressure is 3 1, so the transit time of this weather system is 3 1. According to the time of precipitation, it can also be judged that the weather system 3 1 arrived in Shenyang. So the answer is option B.
