Ekman number

Input(s)

D: Characteristic Length Scale $(\mathrm{m})$

v: Kinematic Eddy Viscosity $\left(\mathrm{m}^{2} / \mathrm{s}\right)$

$\omega$: Angular Velocity of Plenatory Motion (1/s)

$\vartheta$: Latitude (degree)

Output(s)

Ek: Ekman Number (dimensionless)

Formula(s)

$$ \mathrm{Ek}=\frac{\mathrm{v}}{2 * \mathrm{D}^{2} * \omega * \sin \left(\vartheta * \frac{\pi}{180}\right)} $$
