i think it is the ratio of inertia to viscous momentum.

No Ollie

I think its it the inverse of the strouhal number divided by the reynolds number cubed.

No, the Rossby number is the ratio of inertial to Coriolis forces.

This is an important non-dimensional parameter in atmospheric flows with rotating fluids.

Sure, Glenn is right. The definition is

Ro = U / (Omega * L)
