In addition, the national standard (GB/T

1920 1-2006) was approved and released by the national standardization administration Committee on May 9, 2006, and will be officially implemented on June 5, 2006. Two grades of "strong typhoon" and "super typhoon" have been added.

Tropical depression (TD): the maximum wind speed 10.8 ~ 17. 1 m/s, and the maximum wind force near the bottom center is 6-7;

Tropical storm (TS): the maximum wind speed 17.2 ~ 24.4m/s, and the wind force is 8-9;

Severe tropical storm (STS): the maximum wind speed is 24.5 ~ 32.6m/s, and the wind force10-1;

Typhoon (TY): the maximum wind speed is 32.7 ~ 4 1.4m/s, and the wind force is12-13;

Strong typhoon (STY): the maximum wind speed is 4 1.5 ~ 50.9 m/s, and the wind force is14-15;

Super typhoon (super

TY): The maximum wind speed is 5 1.0 m/s, and the wind power 16 or more.
