Dramatic springtime depletions of ozone in polar regions require that polar stratospheric air has a high degree of dynamical isolation and extremely cold temperatures necessary for the formation of polar stratospheric clouds. Both of these conditions are produced within the stratospheric winter polar vortex. Recent aircraft missions have provided new information about the structure of polar vortices during winter and their relation to polar ozone depletions. The aircraft data show that… Expand
The polar vortex refers to a region of the winter polar stratosphere characterized by high nearly zonal westerly winds and isolation from the rest of stratosphere. It is the isolation from the restExpand
The Potential for Ozone Depletion in the Arctic Polar Stratosphere
As the amount of stratospheric chlorine inevitably increases by 50% over the next two decades, ozone losses recognizable as an ozone hole may well appear. Expand
Influence of wave activity on the composition of the polar stratosphere
The planetary wave impact on the polar vortex stability, polar stratosphere temperature, and content of ozone and other gases was simulated with the global chemical–climatic model of the lower andExpand
The impact of polar stratospheric ozone loss on Southern Hemisphere stratospheric circulation and climate
Abstract. The impact of polar stratospheric ozone loss resulting from chlorine activation on polar stratospheric clouds is examined using a pair of model integrations run with the fully coupledExpand
The Relationship between Polar Vortex and Ozone Depletion in the Antarctic Stratosphere during the Period 1979–2016
As the most prominent feature of the polar stratosphere, polar vortex results in widespread changes in the climate system, especially in the ozone variation. In this study, the linkage between polarExpand
Spring polar ozone behavior
Abstract It has been recognized since the commencement of Antarctic ozone measurements during the IGY that spring southern polar total ozone amount is less than spring northern polar total ozoneExpand
Transport of methane in the stratosphere associated with the breakdown of the Antarctic polar vortex
[1] Transport of methane associated with the polar vortex and its breakdown was observed by the data from the Improved Limb Atmospheric Spectrometer (ILAS) during November and December of 1996. TheExpand
Descent of long-lived trace gases in the winter polar vortex
Recent observations of CH4 and HF from the UARS Halogen Limb Occultation Experiment (HALOE) suggest that vigorous descent occurs within the polar winter vortex with “mesospheric” values of CH4Expand
On the magnitude of transport out of the Antarctic polar vortex
The degree of isolation of the Antarctic stratospheric vortex in late winter and spring is investigated quantitatively by using a three-dimensional global tracer transport model, in which theExpand
Influence of transport and mixing in autumn on stratospheric ozone variability over the Arctic in early winter
Early winter ozone mixing ratios in the Arctic middle stratosphere show an interannual variability of about 10%. We show that ozone variability in early January is caused by dynamical processesExpand


Transport into the south polar vortex in early spring
Data collected during the Airborne Antarctic Ozone Experiment during August and September 1987 show conclusively that a photochemical sink and not transport caused the ozone decline during that time.Expand
Evolution of potential vorticity in the winter stratosphere of January‐February 1979
Nimbus 7 Limb Infrared Monitor of the Stratosphere (LIMS) observations are used to study the evolution of potential vorticity in the stratosphere, January–February 1979. Daily analysis of thisExpand
Evidence of the mid-latitude impact of Antarctic ozone depletion
THE 1987 Antarctic Airborne Ozone Expedition established that the springtime depletion of Antarctic ozone1,2 is due to photochemical destruction3 following a preconditioning phase involvingExpand
Reconstruction of the constituent distribution and trends in the Antarctic polar vortex from ER‐2 flight observations
During the Airborne Antarctic Ozone Experiment, the high-altitude ER-2 aircraft measured ozone, chlorine monoxide, and nitrous oxide concentrations in the south polar region. These measurements haveExpand
Synoptic and chemical evolution of the Antarctic vortex in late winter and early spring, 1987
Evidence from the ER-2 and DC-8 aircraft flights is considered, together with analyses of temperature, winds, potential vorticity and trajectories, satellite data, and ozonesonde observations, toExpand
Diagnostic studies of the Antartctic vortex during the 1987 Airborne Antarctic Ozone Experiment: Ozone miniholes
During the Airborne Antarctic Ozone Experiment (AAOE) localized rapid reductions in total ozone, called “miniholes”, were observed by the Total Ozone Mapping Spectrometer (TOMS) within the main ozoneExpand

A Dynamical Model of the Stratospheric Sudden Warming
Abstract The dynamics of the stratosphere sudden warming phenomenon is discussed in terms of the interaction of vertically propagating planetary waves with zonal winds. If global-scale disturbancesExpand
