[netCDF #IKQ-879398]: caluclating wind direction from U and V components

Hi Rich,
If you're using NCO operators like ncap, then the atan() function returns its
result in radians, not degrees, so you should adjust your formula
appropriately. That seems like a reasonable way to do it. I think this would
not necessarily be a good question for the netcdfgroup mailing list, because
it's not really about netCDF, but about converting from cartesian to polar
coordinates. There also may be some knowledge needed of whether the u and v
components of wind speed are relative to the grid or relative to true north and
true east.
