metpy.calc.wind_direction(u, v, convention='from')

Compute the wind direction from u and v-components.

Parameters

  • u (pint.Quantity) – Wind component in the X (East-West) direction

  • v (pint.Quantity) – Wind component in the Y (North-South) direction

  • convention (str) – Convention to return direction; ‘from’ returns the direction the wind is coming from (meteorological convention), ‘to’ returns the direction the wind is going towards (oceanographic convention), default is ‘from’.

Returns
