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 Turkey Wind power in Turkey Wind power in Turkey is gradually expanding in capacity, mainly in the Aegean and Marmara regions. As of July 2017, Turkey had about 6,5 GW of installed capacity and a further 808 MW under construction. The technical wind energy potential is estimated to be about 114 GW of capacity in regions where the wind speed is higher than 7.0 meters above the ground at 50 meters’ height. The first wind farm was built in Izmir in 1998. In 2006, 19 MW of wind power was installed, and in 2007, capacity increased to almost 140 MW. According
