Jovian dynamics. Part III: Multiple, migrating, and equatorial jets

From: Journal of the Atmospheric Sciences | Date: May 15, 2003| Author: | Copyright information

ABSTRACT

Studies of the dynamical response of thin atmospheric layers overlying thick envelopes are extended to examine how multiple jets, such as those seen on Jupiter and Saturn, can be generated and maintained. The jets are produced by baroclinic instabilities and are examined numerical ly using a primitive equation model subject to simple heating functions. The motions are confined to a thin upper layer by a heating that produces a flow with either an exponential vertical structure or one that is linear aloft while vanishing below. The motions are driven by latitudinal heating ...
