How is a typhoon named?
In fact, before the 20th century, when a typhoon came, countries that might be affected by the disaster would give it their own names, which led to many different names for the same typhoon. In order to avoid confusion, 1997, at the 30th meeting of the Typhoon Committee of the World Meteorological Organization held in Hong Kong, the countries and regions concerned decided to standardize the naming of typhoons, namely, Cambodia, China, North Korea, Hong Kong, China, Japan, Laos, Macau, China, Malaysia, China, Philippines, South Korea, Thailand, the United States, Micronesia and Vietnam 14 member countries. Each country or region put forward 10 names to form a typhoon naming table, and decided to apply the new naming method from 1 in 2000. This way, you can use it directly every time a typhoon comes, and then start the cycle from the beginning when all these names are used up.
However, if the typhoon causes great damage, its name will be permanently removed, and then the original nominated area will propose a new name to replace it. For example, the typhoon "Dragon King" in 2005 was removed from the Typhoon Committee because it caused huge economic losses and casualties, and was later replaced by "Anemone" re-nominated by Chinese mainland.
After understanding the naming rules of typhoons, friends in typhoons must pay attention to safety, pay attention to weather news in time, try to stay indoors, close doors and windows and protect themselves.

Tropical cyclone grade:
1, classification principle of tropical cyclones
The classification of tropical cyclones is based on the maximum average wind speed near the bottom center.
2. Classification of tropical cyclones
Tropical cyclones are divided into six grades: tropical depression, tropical storm, strong tropical storm, typhoon, strong typhoon and super typhoon.
The maximum average wind speed near the center of tropical cyclone bottom reaches10.8m/s ~ 17. 1 m/s (the wind force is tropical depression;
It reaches 17.2m/s~24.4m/s (the wind force is 8~9, which is a tropical storm;
It is a strong tropical storm when it reaches 24.5m/s~32.6m/s (wind 10~ 1 1);
Typhoon reaching 32.7m/s ~ 41.4m/s (wind 12~ 13);
A strong typhoon reaches 4 1.5m/s~50.9m/s (wind 14~ 15);
It reaches or exceeds 5 1.0m/s (wind 16 or above is a super typhoon.
