W3FC05

The W3FC05 routine computes the wind direction and speed from given the true
           (Earth Oriented) wind components.

USAGE:    CALL W3FC05 (U, V, DIR, SPD)
                                                                   
   Input argument list:                                           
      U        - REAL   EARTH-ORIENTED U-COMPONENT                
      V        - REAL   EARTH-ORIENTED V-COMPONENT               
                                                                
   Output argument list:      (INCLUDING WORK ARRAYS)        
      DIR      - REAL   WIND DIRECTION, DEGREES.  VALUES WILL
                 BE FROM 0 TO 360 INCLUSIVE.                
      SPD      - REAL   WIND SPEED IN SAME UNITS AS INPUT  
                                                          
REMARKS:
        If speed is less than 1e-10 then direction will be set
        to zero.
