Typhoons are graded from low to high.

Typhoons are graded from low to high.

Typhoons are classified from low to high. China is a typhoon-prone area with strong destructive power. Knowing the basic knowledge of typhoon, the classification level of typhoon and the color of early warning signal will help us to better prevent the arrival of typhoon. The following describes the classification of typhoons from low to high.

Typhoons are classified from low to high. Typhoon 1 is a kind of tropical cyclone, and its grade is a part of tropical cyclone grade.

Tropical cyclones in the South China Sea and the Northwest Pacific are classified into six grades according to the maximum average wind speed near the bottom center, and the wind speed near the center is above 12, which is collectively called typhoon.

The cloud wall around the typhoon eye is dozens of kilometers wide and tens of kilometers high, also known as the eye wall. The clouds are towering here, the wind is whistling, the rain is pouring, the sea is churning, and the weather is the worst.

1, the typhoon warning signal is divided into four levels, which are represented by blue, yellow, orange and red respectively.

2. The blue warning signal of typhoon indicates that it may be or has been affected by tropical cyclones within 24 hours, and the average wind force along the coast or land is above 6, or the gust is above 8 and may continue.

3. The yellow warning signal of typhoon indicates that it may or has been affected by tropical cyclones within 24 hours, and the average wind force along the coast or land is above 8, or the gust is above 10 and may continue.

4. The orange warning signal of typhoon indicates that it may be or has been affected by tropical cyclones within 12 hours, and the average coastal or land wind force is above 10, or the gust is above 12 and may continue.

5. Typhoon red warning signal indicates that it may be or has been affected by tropical cyclones within 6 hours, and the average wind force along the coast or land reaches more than 12, or the gust reaches more than 14 and may continue.

6. Typhoon is a kind of tropical cyclone. According to the National Standard for Tropical Cyclone Grades (GBT 1920 1-2006) issued by China Meteorological Bureau, tropical cyclones are divided into six grades according to the maximum wind speed near the center: super typhoon, strong typhoon, strong tropical storm, tropical storm and tropical depression.

Super typhoon, strong typhoon, typhoon, strong tropical storm, tropical storm, tropical depression. Typhoon grades are classified according to the maximum average wind force near the tropical cyclone centers in the South China Sea and the Northwest Pacific. A tropical cyclone with a central sustained wind speed of17.2m per second is called a typhoon.

What is the reason for the typhoon level from low to high?

Super typhoon: the wind force near the center is above 16, or the gust is 17 and may continue. Strong typhoon: the wind near the center 14 ~ 15, or the gust 15 may continue.

Typhoon: the wind force near the center 12 ~ 13, or the gust 13 may continue. Severe tropical storm: wind 10 ~ 1 1 near the center, or gust 1 1 and may continue.

Tropical storm: the wind near the center is 8 ~ 9, or the gust is 9 and may last. Tropical depression: the wind near the center can reach 6 ~ 7, or the gust is above 7.

Typhoons are divided into 6 levels from low to high. There are 6 levels of typhoons, from low to high, they are tropical depression, tropical storm, tropical storm, typhoon, strong typhoon and super typhoon. Typhoons are classified according to wind power. The higher the wind level, the higher the typhoon level.

The grades of typhoons from low to high are as follows

Typhoon is a kind of tropical cyclone, and its grade is a part of tropical cyclone grade.

In China, tropical cyclones in the South China Sea and the Northwest Pacific are classified into six grades according to the maximum average wind speed near the bottom center, and the wind near the center reaches 12 or above, which is collectively called typhoon.

The cloud wall area around the typhoon eye is tens of kilometers wide and tens of kilometers high, also called eye wall. The cloud wall is towering here, the wind is howling, the rain is pouring, the sea is churning, and the weather is the worst.

Classification of winds: In meteorology, different classifications are made according to the intensity of tropical cyclones. The United Nations World Meteorological Organization has formulated an internationally unified classification standard for tropical cyclones: tropical cyclones with a central maximum wind force of 7 (< 17. 1 m/s =) are called tropical depressions; The maximum wind force in the center reaches 8-9 (17.2-24.4m/s), which is called a tropical storm. A tropical cyclone with a central maximum wind force of10-1(24.5-32.6 m/s) is called a typhoon or hurricane.

New typhoon classification: * * * level is divided into 6 levels. The order from low to high is: ① tropical depression ② tropical storm ③ strong tropical storm ④ typhoon ⑤ strong typhoon ⑤ super typhoon.

Classification of typhoons from low to high 3 What is the correct arrangement of typhoon warning signal color levels from high to low?

The order of typhoon warning signal color level from high to low is red, orange, yellow and blue.

On August 16, 2004, China Meteorological Bureau issued the Trial Measures for Issuing Early Warning Signals of Sudden Meteorological Disasters, which divided typhoon early warning signals into four grades: blue, yellow, orange and red. These include:

The blue warning signal of typhoon indicates that it may be or has been affected by tropical cyclones within 24 hours, and the average wind force along the coast or land is above 6, or the gust is above 8 and may continue.

The yellow warning signal of typhoon indicates that it may or has been affected by tropical cyclones within 24 hours, and the average wind force along the coast or land is above 8, or the gust is above 10 and may continue.

The orange warning signal of typhoon indicates that it may be or has been affected by tropical cyclones within 12 hours, and the average coastal or land wind force is above 10, or the gust is above 12 and may continue.

Typhoon red warning signal indicates that it may or may have been affected by tropical cyclones within 6 hours, with the average wind force along the coast or land reaching more than 12, or the gust reaching more than 14, and it may continue.

Causes of typhoon formation:

Typhoon originated in tropical ocean, where the temperature is high and a large amount of seawater is evaporated into the air, forming a low pressure center. With the change of air pressure and the movement of the earth itself, the inflow of air also rotates, forming a counterclockwise air vortex, which is a tropical cyclone. As long as the temperature does not drop, this tropical cyclone will get stronger and stronger, and finally a typhoon will form.
