Planetary potential vorticity
Webpotential vorticity dynamics. And in situations in which the quasigeostrophic approximation is inadequate, such as for planetary-scale flows, considerations of potential vorticity dynamics on isentropes (or on isopycnals in the ocean) have proven fruitful (see, e.g., Tung 1986; Rhines and Young 1982). WebPotential vorticity anomalies are created by flow across PV contours. Figure 5) illustrates how two sinusoidal PV anomalies can amplify each other. The PV gradient is reversed between the two levels, increasing with y at upper levels and …

Webvorticity" can be described as positive earth vorticity increasing with time. Earth vorticity is always positive (with the only exception of being zero at the equator); earth vorticity ranges from zero at the equator to a value equal to the earth's angular momentum at the pole. WebPlanetary chauvinism is the belief that human society will always be planet-based (even if extended beyond Earth), and overlooks or ignores the potential benefits of space-based living. The idea can be extended to alien society in general. That is, we should expect alien society to be planet based. The coining of the term is often credited to Isaac Asimov, but …
WebPotential vorticity is a measure of the rotation of air masses in the atmosphere, which is related to the conservation of angular momentum. It is defined as the product of the absolute vorticity and the vertical gradient of potential temperature. In simpler terms, potential vorticity represents the amount of rotation that would occur if a ...

It is postulated that internal heating-related compaction is driven by hot isostatic pressing, whereby heat sourced from short-lived ...
http://www-das.uwyo.edu/~geerts/cwx/notes/chap12/pot_vort.html WebThe absolute vorticity is computed from the air velocity relative to an inertial frame, and therefore includes a term due to the Earth's rotation, the Coriolis parameter . The potential vorticity is absolute vorticity divided by the vertical spacing between levels of constant (potential) temperature (or entropy ).

When a fluid rotates, two rotating actions take place: one corresponding to the fluid movementand the other linking to Earth’s rotation. The two processes introduce the idea of the two types of vorticity. See more Rotational movement is a common phenomenon in fluids and, in certain applications, the rotation of the fluid is measured. The two primary measures of fluid … See more Vorticity is of great importance in turbulent flow. However, vorticity is also present in laminar flow.
