http://atmdyn.org/teaching/atmdyn2/2-5_qg_remote.pdf WebThe quasi-geostrophic approximation is a technique used to simplify the quasi-geostrophic equation. This technique assumes that the temperature advection is negligible compared to the Coriolis force and the pressure gradient force. This allows the quasi-geostrophic equation to be expressed in terms of the geopotential height, which is easier to ... deer tick diseases in humans

WebIn the conventional quasi-geostrophic form of the ‘omega’-equation, the forcing of vertical velocity is usually expressed as the sum of two terms associated respectively with … WebAbstract The usual interpretation of the quasi-geostrophic omega equation can be ambiguous, and an alternative but complementary approach is suggested. In the middle troposphere, upward motion is shown to he the consequence of the cyclonic advection of vorticity by the thermal wind. This relates to several empirical-dynamical rules of synoptic … WebUsing the quasi-geostrophic approximation , equation (4) becomes g V v f Vg H g g H a t ζ ζ β ∂ = − •∇ − − ∇ • ∂.
