Determining wind gusts using mean hourly wind speed

WebKnowing the wind sampling average is important, as the value of a one-minute sustained wind is typically 14% greater than a ten-minute sustained wind. A short burst of high speed wind is termed a wind gust , one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval by 10 knots (5 … WebWind Speed Conversion by Tim Brice and Todd Hall Enter a wind speed that you would like: Answers: mph (miles per hour) mph: knots: knots: m/s (meters per second) m/s: ft/s … cryptshare uk

How to Convert a Three-Second Gust to Basic Wind Speed

Typically, for most users of wind data, estimates of the 50-year return period gust or wind speed are required, based on 10–20 (and often fewer) available years of observations. For this situation, the data are generally fitted to a theoretical Webwind See all related content → gust, in meteorology, a sudden increase in wind speed above the average wind speed. More specifically, wind speed must temporarily peak above 16 knots (about 30 km per hour) after accelerating by at least 9–10 knots (about 17–19 km per hour) to qualify as a gust. cryptshare ucr
