Re: Wow! Thanks!
I have yet to read the full article buty I would caution that one fundamental assumption may invalidate the modelling - or at least limit it to special cases.
The model explicity assumes that there is ocean everywhere - i.e. the oceans never pile up in an ice cap on the cold side, and never dry up on the hot side. Further, the atmospheric model only allows for vapour-liquid phase transition, so ice and snow are never explicitly created. This distinctly limits the range of behaviours that may be observed.
I'll read more, and say more later...
