Hi

Anybody know what the gravest mode is (e.g. of a Rossby wave)?

Hi

Does anyone know what is meant by the gravest mode (e.g. of a Rossby
wave). No-one in my research group seems to know. Any definitions?

You might try sci.geo.meteorology for this. I seem to recall
having run across the term, but most of my books are at home.
My guess is that it is the mode with the least number of vertical nodes,

perhaps the barotropic mode. _Geophysical Fluid Dynamics_
by Pedlosky would be the first book I'd reach for, if it was here.

Good luck,
Russell Martin

It is my understanding that the gravest mode is the resonant mode with
the longest wavelength.

The word grave in this context means low pitched.

So the gravest mode would be the lowest frequency/longest wavelength.

I have never seen the word used in the context of Rossby waves, but it
seems to make sense in that context.
