Nonlinear axially symmetric circulations in a nearly inviscid atmosphere.

The structure of certain axially symmetric circulations in a stably stratified, differentially heated, rotating Boussinesq fluid on a sphere is analyzed. A simple approximate theory is developed for the case in which the fluid is sufficiently inviscid that the poleward flow in the Hadley cell is nearly angular momentum conserving. The theory is checked against numerical solutions to the model equations.- from Authors
