Ekman number
The Ekman number ( Ek ) by Vagn Walfrid Ekman is a dimensionless parameter, which mainly takes place in geophysics at the Oceanographic and Atmospheric phenomena using.
It indicates the ratio of viscous forces in the fluid to the Coriolis force.
Where:
- D: the characteristic magnitude of the phenomenon,
- : Kinematic viscosity
- Ω: angular velocity of the Earth's rotation
- : The latitude
- Ro: Rossby number
- Re: Reynolds number
