geostrophic
geostrophic, a. (dʒiːəʊˈstrɒfɪk) [f. geo- + Gr. στροϕή a turning, f. στρέϕειν to turn + -ic.] Of, pertaining to, or caused by the Coriolis force (see Coriolis); usu. applied to a wind (or a current of water) in which there is a balance between the Coriolis force and the horizontal pressure gradient ...

Quasi-geostrophic equations
If the Rossby number is equal to zero then we recover geostrophic flow.
The quasi-geostrophic equations were first formulated by Jule Charney. The quasi-geostrophic vorticity equation can be obtained from the and components of the quasi-geostrophic momentum equation which can then be derived

Frontogenesis
Generally, Rossby number—ratio of inertial to coriolis force
is used to formulate a condition of geostrophic flow. To maintain balance, the geostrophic wind aloft and below adjust, such that regions of divergence/convergence form.

Ocean dynamics
Below the mixed layer the upper ocean is generally governed by the hydrostatic and geostrophic relationships. This Ekman transport is superimposed on geostrophic flow associated with horizontal gradients of density.

地转风
地转风(Geostrophic wind)是一种科氏力和气压梯度力巧妙平衡下产生的一种理论上的风。这个状况称为「地转平衡」。地转风的方向和等压线平行。这种平衡在自然界中很少出现。真正的风几乎总是由地面摩擦力等其他力量产生,与地转风不同。 公式中可能会有其他变数,例如地转风向量可以在恒压表面使用重力位高度 Φ 的形式表示:

Thermal wind
Examples
Advection turning
If a component of the geostrophic wind is parallel to the temperature gradient, the thermal wind will cause the geostrophic If geostrophic wind blows from cold air to warm air (cold advection) the geostrophic wind will turn counterclockwise with height (for the northern hemisphere

Balanced flow
This condition is called geostrophic equilibrium or geostrophic balance (also known as geostrophy). Application
Modelers, theoreticians, and operational forecasters frequently make use of geostrophic/quasi-geostrophic approximation.

Overturning in the Subpolar North Atlantic Program
Geostrophic currents in the basin interior are estimated using temperature and salinity measurements from moorings and gliders. The AMOC is calculated on the basis of the directly measured boundary currents, the geostrophic currents and the Ekman transports estimated from the surface
