A small Rossby number indicates a system is strongly affected by Coriolis forces, and a large Rossby number idicates a system in which inertial forces dominate.
Because the Rossby number is low, the force balance is largely between the pressure gradient force acting towards the low-pressure area and the Coriolis force acting away from the center of the low pressure.
A more correct speed would be that characteristic of the swirl fd, where f is the precession (and sound) frequency, based on the Rossby number.
Now the Rossby number can be derived directly from the dimensionless form of the momentum equation in curvilinear coordinates.
Rossby waves are caused by changes in the Coriolis effect with latitude.
Each large meander, or wave, within the jet stream is known as a Rossby wave (planetary wave).
