<div>Hi Dennis</div><div>I am sorry for my late reply. Please find attached one published article where the author used
wavenumber-frequency spectra in meridional

<div>Hi all<br></div><div><font size="2"><span style="font-family:arial,sans-serif">I have couple of queries regarding wavenumber-freqency plots using "</span></font><b><font size="2"><span style="font-family:arial,sans-serif">mjo_wavenum_freq_season</span></font></b>" which are mentioned below:</div><div>1.
I saw the function calculates wavenumber and frequency. As per my
knowledge, positive frequency correspnds to easward propogating waves
while negative frequency associated with westward waves. But what about
the wavenumber? I mean what the negative wavenumber physically mean?
will you please comment?</div><div>2.
