Rossby Number

(Ro, Kibel Number)
(ratio of inertial to Coriolis force)

The Rossby Number (Ro) is a dimensionless number consisting of the ratio of internal to Coriolis force. It is used in modeling Atmosphere and ocean dynamics. It is defined as:

Ro = U / Lf
  • U - characteristic velocity scale
  • L - characteristic length scale
  • f = 2 Ω sin φ - the Coriolis Frequency where Ω is the angular frequency of rotation and φ is the latitude.
