Industry:Earth science
Describes a balance between vertical pressure gradient and buoyancy forces. Explicitly dp/dz = -\rho g. When this balance does not hold the fluid is non-hydrostatic.
Industry:Earth science
Describes fluid motion disturbed from its average behavior by random fluctuations over a range of temporal and spatial scales.
Industry:Earth science
Describes the synoptic scale disturbance that grows in mid-latitudes due to baroclinic instability.
Industry:Earth science
Descriptive system that determines wind speed by noting the effect of the wind on the environment. Originally developed for use at sea by Admiral Beaufort of the British Navy in 1806.
Industry:Earth science
Dimensionless number relating the ratio of a fluid's capacity to diffuse momentum to its capacity to diffuse heat. Explicitly, the Prandtl number is Pr=\nu/\kappa in which \nu is the kinematic viscosity and \kappa is the thermal diffusivity.
Industry:Earth science
Dimensionless number relating the ratio of inertial forces to thermal diffusion. Explicitly, the Pe'cle't number is Pe=UL/\kappa in which U and L are characteristic velocity and length scales, respectively, and \kappa is the thermal diffusivity.
Industry:Earth science
Dimensionless number relating the ratio of inertial to viscous forces. Explicitly, the Reynolds number is Re=UL/\nu in which U and L are characteristic velocity and length scales, respectively, and \nu is the kinematic viscosity.

Eastward propagating wave centered about the equator with zonal but no meridional velocity. The zonal velocity has a Gaussian meridional structure centered about the equator with standard deviation equal to the equatorial Rossby deformation radius. In the shallow water approximation the waves are non-dispersive with frequency \omega = +/- c k, in which k is the zonal wavenumber and the phase speed c= (gH)^(1/2) with g the acceleration due to gravity and H the mean fluid depth. The equatorial Rossby deformation radius in this case is R=(\beta/c)^(1/2) in which \beta is the meridional gradient of the Coriolis parameter at the equator.

Eddies formed by pinching off of meanders in the Gulf Stream. Eddies forming to the north (coastward side) of the Gulf Stream are called warm core rings and those forming to the south (oceanward side) are called cold core rings.
