Isotherms (left) and azimuthal vorticity (η) contours (right) of the axisymmetric periodic puffing plume state at Gr=3.5x105, Ar=Az=2, AT=1 and σ=7; there are 20 contour levels in [-0,5,0.5] for T and [-105,105] for η.

Isotherms (left) and azimuthal vorticity (η) contours (right) of the axisymmetric periodic puffing plume state at Gr=106, Ar=Az=2, AT=1 and σ=7; there are 20 contour levels in [-0,5,0.5] for T and [-105,105] for η.

(a) Isosurfaces of azimuthal vorticity η of the rotating wave state RW at Gr=2x105, Ar=Az=2, AT=1 and σ=7; the isosurface levels are at η= ±1000.
(b) Isosurfaces of azimuthal vorticity η of the VLF state at Gr=3.5x105, Ar=Az=2, AT=1 and σ=7; the isosurface levels are at η= ±1000.
