Comparison of wind level and wind speed

The China Meteorological Administration issued the “Regulations on Typhoon Operations and Services” in 2001 to supplement typhoons above level 12 to level 17 with Beaufort wind power levels. Level 12 typhoon is set at 32.4-36.9 m/s; level 13 is 37.0-41.4 m/s; level 14 is 41.5-46.1 m/s, level 15 is 46.2-50.9 m/s, level 16 is 51.0-56.0 m/s Second, the level 17 is 56.1-61.2 m/sec.

  • Please note that the unit of wind speed in mild weather is kmph
  • The wind speed listed in this table refers to the wind speed value 10 meters above the ground on flat ground
