The physics of potential vorticity

open access: yesMeteorologische Zeitschrift, 2007
Since the principle of the potential vorticity was published by Hans ERTEL more than sixty years ago (originally in 1942 and later in 1955) a lot of practical applications with numerical or analytical character, as well as interpretative reconstructions ...

A Breakdown in Potential Vorticity Estimation Delineates the Submesoscale‐to‐Turbulence Boundary in Large Eddy Simulations

open access: yesJournal of Advances in Modeling Earth Systems, 2020
Most submesoscale motions—fronts, eddies, filaments, and even large internal waves—are sufficiently rapidly rotating and stratified as to be strongly influenced by potential vorticity dynamics.

Urbanization may enhance tornado potential: A single case report

open access: yesFrontiers in Earth Science, 2023
Tornadoes pose a risk of catastrophic economic loss and casualty in the United States. Modification of land use by urbanization alters the meteorological conditions that may impact tornado formation and intensification processes.

Adiabatic Rearrangement of Hollow PV Towers

open access: yesJournal of Advances in Modeling Earth Systems, 2010
Diabatic heating from deep moist convection in the hurricane eyewall produces a towering annular structure of elevated potential vorticity (PV). This structure has been referred to as a hollow PV tower.

Effect of Typhoon-Generated Cold Wake on the Subsequent Typhoon Tembin and Its Sensitivity to Horizontal Resolutions

open access: yesAtmosphere, 2019
Weather research models have been used to investigate the sensitivity of simulations of Typhoon Tembin (1214) to changes in three horizontal grid spacings and the effect of the cold wake generated by Typhoon Bolaven (1215).

Role of Westerly Jet in Torrential Rainfall During Monsoon Over Northern Pakistan

open access: yesEarth and Space Science, 2020
Pakistan experiences several torrential rainfall events for many years due to interactive role of midlatitude atmospheric and warm moist monsoon circulations.

Tropical cyclone rapid intensification and the excitation of inertia-gravity waves on the edges of an evolving potential vorticity structure

open access: yesFrontiers in Earth Science, 2022
The problem of tropical cyclone rapid intensification is reduced to a potential vorticity (PV) equation and a second order, inhomogeneous, partial differential equation for the azimuthal wind.

Correlation between Buoyancy Flux, Dissipation and Potential Vorticity in Rotating Stratified Turbulence

open access: yesAtmosphere, 2021
We study in this paper the correlation between the buoyancy flux, the efficiency of energy dissipation and the linear and nonlinear components of potential vorticity, PV, a point-wise invariant of the Boussinesq equations, contrasting the three ...

An Intraseasonal Variability in CO2 Over the Arctic Induced by the Madden‐Julian Oscillation

open access: yesGeophysical Research Letters, 2018
Variability of atmospheric CO2 must be well understood for us to better characterize the anthropogenic CO2 release from the surface. A previous study revealed the influence of the Madden‐Julian Oscillation (MJO) to tropical midtropospheric CO2 via ...
