Burger number
Earth science; Oceanography
A dimensionless number comparing the buoyancy with Coriolis forces. Explicitly, the Burger number is Bu = N 2 D 2 /(f 2 L 2 ) in which N is the buoyancy frequency, f is the ...
Richardson number
Earth science; Oceanography
A dimensionless number relating the ratio of buoyancy to inertial forces. In a stratified fluid with characteristic squared buoyancy frequency J,the bulk Richardson number is Ri ...
Froude number
Earth science; Oceanography
A dimensionless number relating the ratio of inertial to buoyancy forces applicable, in particular, to homogeneous shallow water flow, or two layer flow. Explicitly, in the ...
Rossby number
Earth science; Oceanography
A dimensionless number relating the ratio of inertial to Coriolis forces. Explicitly, the Rossby number is Ro=U/(fL) in which U and L are characteristic velocity and horizontal ...
Rossby wave
Earth science; Oceanography
A large scale, westward propagating wave that moves due to isentropic gradients of potential vorticity. Rossby waves are also called planetary waves. In particular, in the ...
Southern Oscillation
Earth science; Oceanography
A large-scale atmospheric and hydrospheric fluctuation centered in the equatorial Pacific Ocean. It exhibits a nearly annual pressure anomaly, alternatively high over the Indian ...
Antarctic High
Earth science; Oceanography
A region of high pressure that occupies central Antarctic throughout the year. This pressure system is responsible for very cold temperatures and extremely low humidity.
