wind_components¶

metpy.calc.wind_components(speed, wdir)[source]¶

Calculate the U, V wind vector components from the speed and direction.

Parameters

speed (pint.Quantity) – The wind speed (magnitude)
wdir (pint.Quantity) – The wind direction, specified as the direction from which the wind is blowing (0-2 pi radians or 0-360 degrees), with 360 degrees being North.

Returns

u, v (tuple of pint.Quantity) – The wind components in the X (East-West) and Y (North-South) directions, respectively.
