Potential vorticity and the PV perspective

  • Brian HoskinsEmail author
Article

Abstract

This paper highlights some theoretical aspects of potential vorticity (PV) and discusses some of the insights the PV perspective has given us. The topics covered include the nature of PV, its controlling role in the symmetric stability of the atmosphere, its inversion to give the flow field, Rossby waves and their coupling to give baroclinic instability, PV and midlatitude weather systems and, finally, insights into tropical motions.
