Thanks Dennis,

I ask my question because when I used the MJO script (exemple 5),
the graph I obtained was very noisy.

Despite the fact that I change the band filter from 20-100 to 2-6 days.

Perhaps because I used daily OLR not anomalies or perhaps because I am using the same weigth.

Sincerely

"Mechanically" speaking, there is no reason why the
scripts could not be applied to other regions.
Just change the lat and lon regions of interest.
For Africa centric analysis it is likely that
data spanning 0-to-360 will have to be 'flipped'
to span -180-to-180 using the "lonFlip" function.

"Scientifically" speaking: Is the 20-100 day band
pass filter used for the MJO appropriate for
AEWs? Are the MJO life-cycle composite diagnostics
applicable to AEWs?

Good luck
