### Rossby radius of deformation

**(Rossby deformation radius)**
(length scale where rotation effects are significant)

The **Rossby radius of deformation**
is the length scale at which rotational effects
are as significant as buoyancy or gravity waves.
It is significant for atmospheres and oceans.
The associated dimensionless parameter is
the Rossby number.

(*atmosphere,weather*)
