uv2dvG_Wrap

Computes the divergence using spherical harmonics given the u and v wind components on a gaussian grid (retains metadata).

Prototype

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl" ; This library is automatically loaded
 ; from NCL V6.2.0 onward.
 ; No need for user to explicitly load.
	function uv2dvG_Wrap (
		u : numeric, 
		v : numeric 
	)
	return_val [dimsizes(u)] : float or double

Arguments

u
v

wind components (input, arrays with two or more dimensions, rightmost two dimensions must be nlat x nlon)

input values must be in ascending latitude order
input array must be on a global grid

Description

This function is identical to uv2dvG, except the return value will have metadata added based on metadata attached to u and v. See the uv2dvG page for full documentation and examples.
