Potential vorticity patterns in Mediterranean “hurricanes”
Geophysical Research Letters, 2017 AbstractThe potential vorticity (PV) anomalies due to the intrusion of dry stratospheric air and those generated by the tropospheric diabatic latent heating are qualitatively analyzed for five Mediterranean tropical‐like cyclones (also known as Medicanes).

The contour-advective semi-Lagrangian hybrid algorithm approach to weather forecasting and freely propagating inertia-gravity waves in the shallow-water system [PDF]
, 2009 This thesis is aimed at extending the spherical barotropic contour-advective semi-Lagrangian (CASL) Algorithm, written in 1996 by David Dritschel and Maarten Ambaum, to more complex test cases within the shallow-water context.

Atmospheric transport and critical layer mixing in the troposphere and stratosphere [PDF]
, 2012 This thesis aims to improve the understanding of transport and critical layer mixing in the troposphere and stratosphere. A dynamical approach is taken based on potential vorticity which has long been recognised as the essential field inducing the flow ...

Boundary Effects in Potential Vorticity Dynamics [PDF]
Journal of the Atmospheric Sciences, 2003 Many aspects of geophysical flows can be described compactly in terms of potential vorticity dynamics. Since potential temperature can fluctuate at boundaries, however, the boundary conditions for potential vorticity dynamics are inhomogeneous, which complicates considerations of potential vorticity dynamics when boundary effects are dynamically ...

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

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.

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.

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.

Process-based classification of Mediterranean cyclones using potential vorticity [PDF]
Weather and Climate DynamicsMediterranean cyclones (MCs) govern extreme weather events across the Euro-African Basin, affecting the lives of hundreds of millions. Despite many studies addressing MCs in the last few decades, their correct simulation and prediction remain a ...
