[ncl-talk] MJO sript

I would imagine that depends on the threshold you pick for "active" and
"inactive" MJO. Usually the PCs are normalized so if the activity is bigger
than one (outside the unit circle in the phase diagram) you know you have
an anomaly bigger than one standard deviation. But that may not be the
threshold you want. You may want 0.5 to include more events, or 2 to only
include very large events. Also you may be interested in MJO events only in
certain locations (Indian Ocean or Maritime Continent). Did you look at the
phase diagram code on the website? If you start with that and modify, it
may do what you want.
