Potential Vorticity Inversion

Daily PV inversion

This section aims at showing some aspects of the interaction of the main PV pattern at 00UTC every day over the Atlantic ocean and western Europe with its environment. PV is split in terms of synoptic scale (high-frequency) PV (...)

PV inversion as a tool for synoptic forecasting

Rationale : upper-level PV patterns or coherent structures are key patterns for mid-latitudes weather system baroclinic development. Satellite images in IR or WV channels and total ozone retrievals may be used to assess initial conditions or very short range forecast of (...)

Potential-Vorticity Inversion ; Low-Order model case

PV inversion is applied in the frame of a shallow-water model with few degrees of freedom but supporting Rossby and gravity waves. Its complete formulation may be found in Lorenz (1980). Intermediate solutions between quasi-geostrophy and the fully non-linear formulation (...)
