Arguments

ra

A two dimensional variable array containing cross correlations as returned by mjo_xcor_lag_season. Nominally: (lag,lat or lon). This will be the color plot.

rb

A two dimensional variable array containing cross correlations as returned by mjo_xcor_lag_season. Nominally: (lag,lat or lon). This will be the overlaid contour line plot.

pltDir

The directory to which the output will be directed. diro="./" means the current directory.

pltType

Graphical type to be generated: "png", "x11", "ps", "eps", "pdf", "ncgm".

pltName

The name associated with the generated graphic. If opt=False, the function will operate under default mode regardless of any attributes associated with the variable.

If opt=True, then the following attributes, associated with opt, may be used to alter the default behavior.

opt@smth9=0.25 or -0.25: If present, the arrays will be smoothed via a heavy [0.25] or light [-0.25] local smoother before being plotted.

Description

This implements the specifications of MJO CLIVAR for lagged correlations.
