Eye-level wind speed

n. The wind speed measured at “eye-level” or 5 to 6 ft above the ground surface.


  • Discussion


Unlike mid-flame wind speed, eye-level wind speed is measured at a specified height (5 to 6 ft) above the ground rather than the vegetation. It is often used in place of mid-flame wind speed because it is much easier to measure.


  • Units


    Preferred units for wind speed are km/hr in technical reports and papers. Fire Management in the United States still uses the English units mi/hr. Engineering and physics applications may use units of m/s or ft/s. See the following wind speed units conversion table for conversion factors.
