Rossby number

(Ro, Kibel number)
(ratio of inertial to Coriolis force)

The Rossby number (Ro) is a dimensionless number consisting of the ratio of inertial (e.g., centrifugal) force to Coriolis force. It is used in modeling atmosphere and ocean dynamics and has been used in modeling circumstellar disks. It is defined as:

Ro = U / Lf

The convective Rossby number, of interest in the study of convection in stars and planets and the resulting dynamos, is the ratio of a buoyancy force to the Coriolis force.
