About typhoons

Typhoon strength and size standards
The Japan Meteorological Agency uses wind speed (10-minute average) to indicate the size and strength of a typhoon. The size is divided by the radius of the strong wind area (the area where winds of 15 km/h or higher are blowing or are likely to blow), and the strength is divided by the maximum wind speed.
Typhoon strength
| class | Maximum wind speed (㎧ = meters per second: distance in 1 second) |
|---|---|
| strong | 33㎧ (64 knots) or more - less than 44㎧ (85 knots) |
| very strong | 44㎧ (85 knots) or more - less than 54㎧ (105 knots) |
| ferocious | 54㎧ (85 knots) or more |
Typhoon size
