Rotating reynolds number
From Glossary of Meteorology
rotating Reynolds number
(Or rotation Reynolds number.) A nondimensional number arising in problems of a rotating viscous fluid.
It may appear either as Ωh2/ν, in which case it equals one-half the square root of the Taylor number, or as Ωr2/ν, where r is a suitable radius, h a representative depth, Ω the absolute angular speed, and ν the kinematic viscosity.
