This form of potential vorticity is here referred to as "neutral-surface potential vorticity", NSPV. Its epineutral variations can be significantly different to those of the two other commonly used potential vorticity variables, IPV, and fN 2. The difference between NSPV and fN 2 is shown to...

This chapter introduces the most important unifying concepts in rotating fluid dynamics, the concept of potential vorticity. The principle is closely related to the Kelvin circulation theorem. The chapter focuses on the principle of potential vorticity conservation rather intuitively. It examines the prope...
In these highly developed areas of geophysical fluid dynamics a key role is played by the concept of potential vorticity (PV). This pseudoscalar quantity—defined as the reciprocal of the density of the fluid multiplied by the scalar product of the vorticity vector and the gradient of any .....
Structures of adjoint sensitivities to potential vorticity for specific initial and final norm are investigated for a short-range cyclone forecast in a three-dimensional quasigeostrophic (QG) model. Moreover, adjoint sensitivities to potential vorticity are compared with nonlinear sensitivities calculated ...
