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 power in Thailand resource map with 13 year-long data (1966-1978) from 53 wind speed measurement stations of the TMD, using power law to standardize all wind speed to 10 m. In 1984, another similar attempt was carried out by KMITT, using 17 year-long (1966-1982) data from 62 measurement stations, and with financial support from USAID. Attempts at producing wind resource maps of Thailand all faced the problem of shortage in wind speed data, especially offshore and at high elevations. This resulted in maps with low coverage. In 2001, another set of wind resource maps was produced by DEDE using data from over 150
