How is wind speed calculated

WebThe wind direction can be calculated using trigonometric functions: Angle = arctan (V/U), this is valid as long as U is not equal to zero. You must also adjust for what quadrant you are in based on whether U and V are positive or negative. The built-in arctan2 () function in R and some other programming languages will handle this.
