W3FC02
The W3FC02 routine given the grid-oriented wind components on a Northern
hemisphere polar stereographic grid point, compute the direction
and speed of the wind at that point.
USAGE: CALL W3FC02 (FFID, FFJD, FGU, FGV, DIR, SPD)
INPUT VARIABLES:
FFID ARG LIST REAL*4 I(NORTH POLE) - I(POINT)
FFJD ARG LIST REAL*4 J(NORTH POLE) - J(POINT)
FGU ARG LIST REAL*4 GRID-ORIENTED U-COMPONENT
FGV ARG LIST REAL*4 GRID-ORIENTED V-COMPONENT
OUTPUT VARIABLES:
DIR ARG LIST REAL*4 WIND DIRECTION, DEGREES
SPD ARG LIST REAL*4 WIND SPEED
