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
Wind transducer Wind transducer A wind transducer is a device used by sailors to receive a real-time measurement of wind speed and direction. A wind transducer is usually mounted on the masthead of a sailing boat and is occasionally used by power boats too. The wind speed and direction measurements are more critical to sailing boats than to power boats. Sailors rely on the wind speed and direction to help with navigation and pilotage. These devices can be calibrated to measure the true wind speed and the apparent wind speed (speed that a sailor would 'feel'). Sailing boats can sail at a
