	Subroutine that computes geo streamfunction.

Detailed Description

Subroutine that computes geo streamfunction.

This routine computes the geostrophic streamfunction, PSI, from the passed geopotential height field, Z.
The formule used it PSI = G*Z/F0, where G is the gravitational acceleration constant and F0 is a constant Coriolis parameter. F0 is set to be the valus of the Coriolis parameter near the center of the model grid.

Parameters

[in]	Z1D	Geopotential height (m).
[out]	STRM	Geostrophic streamfunction.
