Note by the way that calculating wind speed as sqrt(u^2+v^2) doesn't take account of the map factor, so it is only approximately correct. The steps below assume that you have a point feature class with the attribute fields u and v.

The Gribtype And Resolution Can Also Be Changed.

Returns a data.frame or zoo object (depending on input u) with two columns named dd and ff containing wind speed (same physical unit as input u/v) and wind direction.wind direction is either in meteorological degrees (0 from north, from 90 east, 180 from south, and 270 from west) or in mathematical radiant if input rad = true. Array size and shape must match wdir. U = ws * cos(θ) v = ws * sin(θ) where θ is the wind direction using math direction, and ws is the wind speed (ie.

U = Ws * Cos(Θ) V = Ws * Sin(Θ) Where Θ Is The Wind Direction Using Math.
