Potential Vorticity Inversion on a Hemisphere
Several different kinds of accurate potential vorticity (PV) inversion operators, and the associated balanced models, are tested for the shallow water equations on a hemisphere in an attempt to approach the ultimate limitations of the balance, inversion, and slow-manifold concepts. The accuracies achieved are far higher than for standard balanced models accurate to one or two orders in Rossby n...
متن کاملProgress of Research on Potential Vorticity and its Inversion
In this paper potential vorticity (PV) and potential vorticity inversion (PVI) and their application in the cyclogenesis and mesoscale meteorological phenomena are reviewed. PV has been served as a powerful and useful dynamic tracer for the understanding of the large-scale dynamics and synoptic variations in the atmosphere and oceans. Significant progress has been made on the application of PV ...
متن کاملPrecipitating Quasigeostrophic Equations and Potential Vorticity Inversion with Phase Changes
Precipitating versions of the quasigeostrophic (QG) equations are derived systematically, starting from the equations of a cloud-resolving model. The presence of phase changes of water from vapor to liquid and vice versa leads to important differences from the dry QG case. The precipitating QG (PQG) equations, in their simplest form, have two variables to describe the full system: a potential v...
متن کاملBalance, Potential-vorticity Inversion, Lighthill Radiation, and the Slow Quasimanifold
Practically our entire understanding of large-scale atmosphere–ocean dynamics depends on the notions of balance and potential-vorticity inversion. These are essential, for instance, for a clear understanding of the basic Rossby-wave propagation mechanism, or quasi-elasticity, that underlies almost every large-scale fluid-dynamical phenomenon of meteorological and oceanographical interest, from ...
متن کاملComments on ‘On the use and significance of isentropic potential vorticity maps ’ by
The authors are to be congratulated on their excellent survey of the use of potential vorticity (PV). I guess that we are impressed that modern observations and analysis techniques are sufficiently accurate to determine PV reliably, and that it is so difficult to invert compared with (say) the quasi-geostrophic variety. But one aspect of their story worries me. It concerns the nature of the bou...
