Atmosphere, 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 ...

On the mix-down times of dynamically active potential vorticity filaments
, 1999 A simple model is used to study the evolution of potential vorticity filaments, viewed in cross-section, subject to steady shear and deformation flows representative of the large-scale atmospheric circulation.

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

Analysis of the cooling episode in Western Romania in the first half of April 2025 using upper troposphere maps [PDF]
Journal of Central European AgricultureThe first decade of April was characterised by particularly cold weather with minimum temperatures that were daily or even monthly records. The cooling of the weather occurred starting on April 6 and lasted until after April 10, producing late frost with

A balanced approach to modelling rotating stably stratified geophysical flows
, 2003 This work was the first to show how one can rewrite the equations for a rotating stratified fluid in a way which makes potential vorticity conservation explicit.

On the beta-drift of an initially circular vortex patch [PDF]
, 2001 The nonlinear inviscid evolution of a vortex patch in a single-layer quasi-geostrophic fluid and within a background planetary vorticity gradient is examined numerically at unprecedented spatial resolution.

Gradient evolution for potential vorticity flows [PDF]
Nonlinear Processes in Geophysics, 2001 Two-dimensional unsteady incompressible flows in which the potential vorticity (PV) plays a key role are examined in this study, through the development of the evolution equation for the PV gradient.

Influence of sudden stratospheric warmings on tropospheric winds
Meteorologische Zeitschrift, 2011 The influence of changes in the zonal mean stratospheric potential vorticity, associated with sudden stratospheric warmings, on the zonal mean zonal wind in the troposphere is investigated by piecewise potential vorticity inversion.

Organisation of potential vorticity on the mesoscale during deep moist convection [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2015 Potential vorticity (PV) and its conservation principle elegantly describe large-scale atmospheric dynamics. On the mesoscale, however, PV has received less attention.
