Webpressure surface and therefore through thermal wind the geostrophic wind does not vary with height. In contrast a ﬂuid is Baroclinic if the term ∇ρ × ∇p 6= 0, for example if temperature varies on a pressure surface then ρ = ρ(p,T) and the ﬂuid is baroclinic. In a baroclinic ﬂuid the geostrophic wind will vary with height and WebUnderstand “rules of thumb” for geostrophic flow and how they apply to water flow, isobars, and isopycnals. 10/27/2024 MARS 6080 3 Geostrophic Flow - Outline ...

"WebThe flow of air is deflected by the rotation of the earth, and the resultant geostrophic wind blows parallel to notional lines of equal pressure (isobars) around the areas of high and low pressure. Where the gradient of pressure is intense, there is an additional rotational element known as vorticity which deflects the geostrophic wind. " - Define geostrophic flow
