w3ft43v()

subroutine w3ft43v	(	real, dimension(361,181)	alola,
		real, dimension(npts)	apola,
			interp
	)

Convert a global 1.0 degree lat.,lon.

361 by 181 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	361*181 grid 1.0 deg. lat,lon grid n. hemi. 65341 point grid. 360 * 181 one degree grib grid 3 was flipped, greenwish added to right side to make 361 * 181.
[in]	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

Note

• 1. W1 and w2 are used to store sets of constants which are reusable for repeated calls to the subroutine. 20 other arrays are saved and reused on the next 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 about 1100 points below the equator will be in this map.
