How to prevent typhoon grade during the landing of typhoon mangosteen

According to the latest release of the Central Meteorological Observatory, typhoon mangosteen will enter the eastern part of the South China Sea on the 15th in Luzon Island, Philippines, and approach the coastal area of Guangdong Province. Is there any preventive measures against typhoon weather? How is the grade of typhoon divided? Let's get to know with Xiaobian.

What are the levels of Typhoon

According to their intensity, tropical cyclones can be divided into six grades: tropical depression, tropical storm, strong tropical storm, typhoon, strong typhoon and super typhoon.

How to classify typhoon

Since 1989, China has adopted the International Tropical Cyclone name and grade standard. According to international practice, China's tropical cyclones in the west of the North Pacific and the South China Sea are divided into:

Tropical depression, with a maximum wind speed of 6-7 grades (10.8-17.1 M / s);

Tropical storm, with the maximum wind speed of 8-9 grades (17.2-24.4m / s);

Strong tropical storm with maximum wind speed of 10-11 (24.5-32.6m / s);

Typhoon, the maximum wind speed is 12-13, 32.7m/s-41.4m/s;

Strong typhoon with maximum wind speed of 14-15 (41.5m / s-50.9m / s);

Super typhoon with maximum wind speed of & Ge; 16.
