In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature. Wind speed is now commonly measured with an anemometer. Wind speed affects weather forecasting, aviation and maritime operations, construction projects, growth and metabolism rate of many plant species, and h… WebTo find the wind speed = apply this formula WS=SQRT ( (x^2)+ (y^2)) If it is in Meters per Second, be sure to convert to Knots if needed. To find the wind direction = apply this formula WD=ATAN2 (y,x) where Y == to North/South vector and the X == the East/West vector. Once you run this formula, you will be presented with a degree in radian format.
