[ncl-talk] How to plot significance of fractional variance (MJO)

[Lyndz]

Dear NCL experts,

I would like to plot the significance of the MJO (30-60 ISO) band similar
to Figure 8 of Hartmann and Michelsen 1989 (
https://journals.ametsoc.org/view/journals/atsc/46/18/1520-0469_1989_046_2838_ipiir_2_0_co_2.xml
)

I found an example in the NCL webpage that plots the fractional variance:
https://www.ncl.ucar.edu/Applications/Scripts/mjoclivar_3.ncl

How can I plot the significance from here (above the red noise?)

I'll appreciate any help on this.

Sincerely,
Lyndz
