Rossby Number
The Rossby Number describes the importance of the rotation of the frame on the flow. It is the ratio of the inertial force (e.g. buoyancy) of the fluid to the Coriolis force imposed by rotation. A larger Rossby number will mean the flow’s behavior is less dependent on the rotation. where describes the typical magnitude of the horizontal flow components, is the rotation rate, is the latitude of the fluid parcel on a sphere (e.g. Earth), f is the…
