w3fc06()

subroutine w3fc06	(		dir,
			spd,
			u,
			v
	)

Given the wind direction and speed, compute Earth-oriented (true) wind components.

Input direction at the pole point must be consistent with WMO conventions, and output components will follow those conventions. (See office note 241 for WMO definition.)

Parameters

[in]	DIR	REAL*4 Wind direction, degrees
[in]	SPD	REAL*4 Wind speed, any units
[out]	U	REAL*4 Earth-oriented U-component.
[out]	V	REAL*4 Earth-oriented V-component.

Note

This code will not vectorize on cray, you could put the four lines in your code with a couple of do loops.
