Called PV because there is the “potential” for generating vorticity by changing latitude or changing stability. Since is negative for synoptic scale motions, ...

9 апр. 2015 г. · Note that as the isentropic potential vorticity is conserved following the flow on an isentropic surface, so too is potential temperature.

The potential vorticity (PV) is the absolute circulation of an air parcel that is enclosed between two isentropic surfaces.

In fluid mechanics, potential vorticity (PV) is a quantity which is proportional to the dot product of vorticity and stratification.

Chapter 9: Isentropic potential vorticity & mid- latitude ... Robertson, 1985: On the use and significance of isentropic potential vorticity maps.

Potential vorticity is calculated from the nonlinear gradient wind balance using temperature and geopotential fields, since the wind field is not available in ...

On an isentropic surface the potential vorticity PV is a product of absolute vorticity and static stability. One of the most important application of PV is ...
