Re: How to extract equatorial waves by filtering in the wheeler-kiladis wavenumber-frequency domain.

I'm not sure if there is anything built into ncl to do this. However, I've
written a function that does it. The function is in the attached file
kf_filter.ncl. Also attached is a sample program, spacetime.ncl, that uses
this filter to filter for Kelvin waves. You can change the parameters to
filter for other waves.

Hope this helps.
