w3ft05v()

subroutine w3ft05v	(	real, dimension(145,37)	alola,
		real, dimension(4225)	apola,
			interp
	)

Convert a northern hemisphere 2.5 degree lat.,lon.

145 by 37 grid to a polar stereographic 65 by 65 grid. The polar stereographic map projection is true at 60 deg. n. , The mesh length is 381 km. and the oriention is 80 deg. w.

Parameters

[in]	ALOLA	145*37 gid 2.5 lat,lon grid n. hemisphere 5365 point grid is o.n. 84 type 29 or 1d hex interp - 1 linear interpolation , ne.1 biquadratic
[out]	APOLA	65*65 grid of northern hemisphere 4225 point grid is o.n.84 type 27 or 1b hex.
	INTERP

Remarks

• 1. W1 and w2 are used to store sets of constants which are reusable for repeated calls to the subroutine.
• 2. Wind components are not rotated to the 65*65 grid orientation after interpolation. you may use w3fc08 to do this.
• 3. The grid points values on the equator have been extrapolated outward to all the grid points outside the equator on the 65*65 grid (about 1100 points).
