In order to produce a wind speed distribution using measured data wind speed bins are used to group and count the individual values for wind speed. The wind direction is calculated using the arctan function and checking if the wind is a headwind of a tailwind WS Wind Speed WD Wind Direction TC True Course TH True Heading TAS True Airspeed GS Groundspeed Here is the formula for the wind speed you can use this in Excel provided you use Named Ranges. You can select a range of dates in the results on the.
D wind mill diameter m Be aware that the density of air decreases with temperature and altitude and that the major factor in wind power generation is wind speed.
