once i looked at short video clip of jupiter atmosphere. i have questions in mind: 1. why the atmosphere seems to travel at different speed making up a number of sliding rings?why don't they travel together? 2. what makes the pattern of turbulence so huge? i think we need such an incredible viscousity to produce such an effect. why don't they break up into tiny curls? i never learn astronomy, so please excuse my silly questions if they sound very trivial.
