Surface Gustiness and Wind Speed Range as a Function of Time Interval and Mean Wind Speed

open access: yesJournal of Applied Meteorology, 1975
Abstract Approximately 100 hours of wind records with mean speeds of 20 to 100 kt (at 12 m) were obtained from the Mt. Washington Observatory. Analyses of these data indicate that the gust factor can be used to describe the relationship between mean wind speed and wind speed range for a specific interval of time. Pooled data recorded at 14 airfields in
