Typhoon intensity level

Typhoon intensity levels are divided into six levels, namely tropical depression, tropical storm, severe tropical storm, typhoon, severe typhoon and super typhoon.

1. Tropical depression (Tropical depression), maximum wind speed of level 6 to level 7 (10.8 to 17.1m/s).

2. Tropical storm, maximum wind speed of level 8 to level 9 (17.2 to 24.4m/s).

3. Severe tropical storm, with maximum wind speed of level 10 to level 11 (24.5 to 32.6m/s).

4. Typhoon (Typhoon), the maximum wind speed is 12 to 13 levels, (32.7 to 41.4m/s).

5. Severe typhoon, with maximum wind speed of 14 to 15 levels (41.5 to 50.9m/s).

6. Super Typhoon (Super Typhoon), maximum wind speed ≥16 (≥51.0m/s).

Introduction to typhoons

Typhoon (English: Typhoon) is a type of tropical cyclone. A tropical cyclone is a low-pressure vortex that occurs on the tropical or subtropical ocean. It is a powerful and deep "tropical weather system." China divides tropical cyclones in the northwest Pacific into six levels based on the maximum average wind power (wind speed) near the bottom center. Those with wind speeds of level 12 or above near the center are collectively called typhoons.

Typhoons often bring violent winds, heavy rains and storm surges, which not only bring disasters to mankind, but also bring benefits to mankind. Typhoons bring abundant freshwater resources to mankind, which is of great significance for improving freshwater supply and ecological environment.

In addition, typhoons also maintain a relative balance between heat and cold in various parts of the world; the equatorial region has a hot climate. If typhoons had not dissipated this heat, the tropics would be hotter, the frigid zones would be colder, and the temperate zones would disappear from the earth.
