Apparent wind in knots and degrees. Note that a number of additional factors come into play when converting the measurements from the masthead anemometer into the true wind if a high degree of accuracy is required, including the following: In the presence of a current, the true wind is considered to be that measured on the craft drifting with the water over the bottom, and wind with respect to the sea bed as the "ground" or "geographical wind". The apparent wind on board (a boat) is often quoted as a speed measured by a masthead transducer containing an anemometer and wind vane
Wind power in Thailand energy by developing renewable energy sources in Thailand, including wind power. The first study of Thai wind energy potential was conducted in 1975 by the Department of Energy Development and Promotion, which is now called the Department of Alternative Energy Development and Efficiency (DEDE). Data of mean wind speed from the Thai Meteorological Department (TMD) was used to produce a wind map of areas with medium to high potential. Later, in 1981, King Mongkut's Institute of Technology Thonburi (KMITT) and King Mongkut's Institute of Technology North Bangkok (KMITNB), in cooperation with Electricity Generating Authority of Thailand (EGAT), produced another wind
