Geoff Vallis and Jurgen Theiss have started a list serve for Atmosphere-Ocean discussion. (Great idea!) Please pass the word.
Perhaps we can start things off with the following question that occurred to me during a journal club meeting with the UT-Austin GFD club.
"Why don't KAM barriers to transport qualify as a fully nonlinear
theory that explains the inhibition to mixing at small spatial scales?" We were discussing the following article, that states that there is no such fully nonlinear theory. I'd never heard of "KAM barriers" before, but from what Harry explained, these seem to qualify. He was concerned that they only strictly apply to 2d turbulence, but I argue that's good enough -- see attached excerpts from my summary of the meeting to put this question in context.
