Abstract

Two dimensional flows on a rotating sphere have been studied from view points of flow dynamics on a compact region with no boundary and also of zonal-jet formation in planetary atmospheres. Especially fundamental solutions of Rossby waves, which are represented by spherical harmonics, were subjects of inviscid nonlinear stability analysis in 1970s, but their bifurcation structures in nonlinear stage are not clear yet. Here we report numerical results on the bifurcation structure arising from two- or three-jet solution on a rotating and non-rotating sphere, in comparison with that on two-dimensional flat torus.
