Rossby regime

A type of flow pattern in a rotating fluid with differential radial heating in which the major radial transport of heat and momentum is effected by horizontal eddies of low wavenumber.

This regime occurs for low values of the Rossby number (on the order of 0.1). The term has been used in connection with dishpan experiments, but applies as well to the atmosphere of the earth and other planets.
