Structural changes of self-organized vortices in Jupiter atmospheres such asGreat Red Spot (GRS) and White Ovals are demonstrated using anelectrostatically bounded charged dust cloud in an unbounded streaming plasmaas the prototype for various driven-dissipative complex flow systems in nature.Using a 2D hydrodynamic model, the steady state flow solutions are obtained forthe volumetrically driven dust cloud in a bounded domain of aspect-ratio of 1.5relevant to the current size of GRS and a driving sheared ion flow similar tothe part of zonal jets streaming through the GRS. These nonlinear solutionsreveal many similar characteristic features between the steadily driven dustcirculation in laboratory experiments and the vortices in Jupiter atmosphere.Starting from the continuous structural changes, the persistence of high-speedcollar ring around the quiescent interior of uniform vorticity of GRS and WhiteOvals are interpreted as a consequence of changes in internal propertiesrelated to kinematic viscosity rather than the driving fields. This theanalysis also sheds light on the roles of driving field, boundaries, anddynamical parameters regime in determining the characteristic size, thestrength, the circulating direction, and the drift of the vortices in Jupiteratmosphere and other relevant driven-dissipative flow systems in nature.
