Tracking Surface Cyclones with Moist Potential Vorticity
Surface cyclone tracks are investigated in the context of moist potential vorticity (MPV). A prognostic equation of surface absolute vorticity is derived which provides a basis for using negative MPV (NMPV) in the troposphere as an alternative approach to track surface cyclones. An observed case study of explosive lee cyclogenesis is performed to test the effectiveness of the MPV approach. It i...

متن کاملPotential vorticity 1
LTEX source, defined here to print as italic. Possible cross-references to other articles are flagged \crossref{...}. For visibility, \crossref{...} is temporarily defined to print as sans-serif. Therefore, sans-serif italic signals both a new term and a possible cross-reference. I have used \openingscarequote...\closingscarequote in a few places. This bends the house-style rules, but unfortuna...
متن کاملPotential Vorticity as Meridional Coordinate
The dynamical equations of atmospheric flow are written using potential vorticity as the meridional coordinate and potential temperature as the vertical coordinate. Within this system, the atmosphere is divided into undulating tubes bounded by isentropic and constant potential vorticity surfaces, and, under adiabatic and frictionless conditions, the air moves through the tubes without penetrati...
متن کاملIdealised simulations of sting-jet cyclones
An idealised modelling study of sting-jet cyclones is presented. Sting jets are descending mesoscale jets that occur in some extratropical cyclones and produce localised regions of strong low-level winds in the frontal fracture region. Moist baroclinic lifecycle (LC1) simulations are performed with modifications to produce cyclones resembling observed sting-jet cyclones. A sting jet exists in t...
