Wind gust World Meteorological Organization. Any significant variation at this mean wind during the ten minutes preceding the observation are noted as gusts in messages such as METAR. It is generally reported in METAR when the peak wind speed reaches at least 16 knots and the variation in wind speed between the peaks and average wind is at least 9 to 10 knots. In marine meteorology, the top speed of a burst is expressed in meters per second (m/s) or in knots, while the Beaufort scale is used for reporting the mean speed. When the maximum speed exceeds the average speed by
Speed of the Wind Speed of the Wind Speed of the Wind was a record-breaking car of the 1930s, built for and driven by Captain George Eyston. The car was designed by Eyston and E A D Eldridge, then built by the father of Tom Delaney It was powered by an unsupercharged version of the V-12 Rolls-Royce Kestrel aero engine. The car was too large and heavy for circuit racing and was already underpowered by the standards of the absolute speed record breakers. This car was designed for "endurance", more than peak power. Running a supercharged engine with the fuel and materials technology of
