This paper investigates the relationship between high latitude upper mesospheric winds and the state of the stratospheric polar vortex in the absence of major sudden stratospheric warmings. A ground b...
Middle atmospheric water vapour and dynamics in the vicinity of the polar vortex during the Hygrosonde-2 campaign
Middle atmospheric water vapour polar vortex Hygrosonde-2 campaign
font style='font-size:12px;'>
2009/7/15
The Hygrosonde-2 campaign took place on 16 December 2001 at Esrange/Sweden (68° N, 21° E) with the aim to investigate the small scale distribution of water vapour in the middle atmosphere in the vicin...
The impact of model grid zooming on tracer transport in the 1999/2000 Arctic polar vortex

We have used a 3D chemistry transport model to evaluate the transport of HF and CH4 in the stratosphere during the Arctic winter of 1999/2000. Several model experiments were carried out with the use o...
Evidence for long-lived polar vortex air in the mid-latitude summer stratosphere from in situ laser diode CH4 and H2O measurements

A balloon borne diode laser spectrometer was launched in southern France in June 2000 to yield in situ stratospheric CH4 and H2O measurements. In the altitude region ranging from 20km to 25km, strikin...
The North Atlantic variability structure, storm tracks, and precipitation depending on the polar vortex strength
North Atlantic variability structure storm tracks polar vortex strength

Motivated by the strong evidence that the state of the northern hemisphere vortex in boreal winter influences tropospheric variability, teleconnection patterns over the North Atlantic are defined sepa...
Impact of mixing and chemical change on ozone-tracer relations in the polar vortex
mixing and chemical change ozone-tracer relations polar vortex
font style='font-size:12px;'>
2009/1/14
Tracer-tracer relations have been used for a long time to separate physico-chemical change from change caused by transport processes. In particular, for more than a decade, ozone-tracer relations have...
The influence of polar vortex ozone depletion on NH mid-latitude ozone trends in spring

2009/1/13
Reverse domain-filling trajectory calculations have been performed for the years 1993, 1995, 1996, 1997, and 2000 to calculate the spreading of ozone depleted air from the polar vortex to midlatitudes...
The impact of transport across the polar vortex edge on Match ozone loss estimates
transport polar vortex match ozone loss estimates
font style='font-size:12px;'>
2008/10/28
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. For the winter 2002/03, we...
