[gradsusr] Get direction of max wind in hourly time serie of a point

[Martin V. Mathew]

Hi
I think you can try following two steps to obtain the direction of maximum
wind.

First you have to find the hour of the day in which have maximum wind speed
(use mag and maxloc commands).

After identifying the particular hour use trigonometric function *atan2() *to
obtain the angle.
