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 highest wind energy potential in Thailand. The stations were installed to measure wind speeds at 80, 90, and 100 m heights. Also, from 2007 to 2009 wind speed and direction were measured and recorded from several stations in the northern Thailand. In 2011, research to improve the wind map was conducted by the Department of Physics of Silpakorn University. The research produced mesoscale wind maps with resolution of 3x3 km cells using atmospheric model and computer simulation software, and also experimented with the making of microscale wind maps, which could be the next step in the study of Thai wind
