calcMonAnomLLLT

Calculates monthly anomalies by subtracting the long term mean from each point (lev,lat,lon,time version)

Prototype

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"

	function calcMonAnomLLLT (
		x     [*][*][*][*] : numeric,  
		xAve [*][*][*][12] : numeric   
	)

	return_val [dimsizes(x)] :  numeric

Arguments

x

A four-dimensional array of any numeric type. Dimensions must be lev,lat, lon, time. The time dimension must be a multiple of 12.

xAve

A four-dimensional array equal to the monthly averages of x. The leftmost three dimensions are lev,lat,lon, while the rightmost must be of size 12.

Return value

An array of the same size and type as x.

Description

Calculates climatological anomalies by subtracting the long term mean from each point. Assumes monthly data. If the input data contains metadata (e.g. coordinate variables and attributes), these will be retained.
