Impact of strong and weak stratospheric polar vortices on geomagnetic semidiurnal solar and lunar tides

Earth, Planets and Space, 2023
The impact of strong and weak stratospheric polar vortices on geomagnetic semidiurnal solar and lunar tides is investigated during Northern Hemisphere (NH) winters using ground-based magnetic field observations at the Huancayo (12.05° S, 284.67° E ...

Evolution of the intensity and duration of the Southern Hemisphere stratospheric polar vortex edge for the period 1979–2020 [PDF]

Atmospheric Chemistry and Physics, 2022
The intensity and position of the Southern Hemisphere stratospheric polar vortex edge is evaluated as a function of equivalent latitude over the period 1979–2020 on three isentropic levels (475, 550, and 675 K) from ECMWF ERA-Interim reanalysis.

Unconventional Vortices and Phase Transitions in Rapidly Rotating Superfluid ^{3}He [PDF]

, 2002
This paper studies vortex-lattice phases of rapidly rotating superfluid ^3He based on the Ginzburg-Landau free-energy functional. To identify stable phases in the p-Omega plane (p: pressure; Omega: angular velocity), the functional is minimized with the ...

The Relationship between Polar Vortex and Ozone Depletion in the Antarctic Stratosphere during the Period 1979–2016

Advances in Meteorology, 2017
As the most prominent feature of the polar stratosphere, polar vortex results in widespread changes in the climate system, especially in the ozone variation.

Pathways of Influence Between Northern Hemisphere Blocking and Stratospheric Polar Vortex Variability

Geophysical Research Letters, 2022
We apply a causal inference‐based framework to test and quantify previously suggested causal relationships between Northern Hemisphere blocking, upward wave‐activity fluxes and stratospheric polar vortex (SPV) variability using reanalysis data.

The impact of mixing across the polar vortex edge on Match ozone loss estimates [PDF]

, 2007
The Match method for quantification of polar chemical ozone loss is investigated mainly with respect to the impact of mixing across the vortex edge onto this estimate. We show for the winter 2002/03 that significant mixing across the vortex edge occurred

Observation and simulation of wave breaking in the southern hemispheric stratosphere during VORCORE [PDF]

Annales Geophysicae, 2013
An interesting occurrence of a Rossby wave breaking event observed during the VORCORE experiment is presented and explained. Twenty-seven balloons were launched inside the Antarctic polar vortex.

The effect of interactive ozone chemistry on weak and strong stratospheric polar vortex events [PDF]

Atmospheric Chemistry and Physics, 2020
Modeling and observational studies have reported effects of stratospheric ozone extremes on Northern Hemisphere spring climate. Recent work has further suggested that the coupling of ozone chemistry and dynamics amplifies the surface response to ...

The impact of transport across the polar vortex edge on Match ozone loss estimates [PDF]

, 2008
The Match method for the quantification of polar chemical ozone loss is investigated mainly with respect to the impact of the transport of air masses across the vortex edge.
