Wind Speed 6
Wind Speed 6 : The rate of horizontal motion of the air past a given point expressed in terms of distance per unit of time. In the Canadian Forest Fire Danger Rating System and in fire weather forecasts , wind speed is assumed to be measured or estimated at the international standard height of 10 metres (m) in the open on level terrain or at 10 m above a closed vegetative canopy. If determined with an anemometer, wind speed for fire management purposes is normally averaged over a 10-minute interval. Recommended SI unit is kilometres per hour (km/h)
