Rossby Number

Roosby number ( \(Ro\) ) (dimensionless number) used in describing fluid flow. It is the ratio of internal to Coriolis force.

Rossby Number Formula

\(Ro =  \frac{ U } { L f} \)

Where:

\(Ro\) = Roosby Number

\(U\) = characteristic velocity

\(L\) = characteristic length

\(f\) = Coriolis frequency
