During winter and springtime, the flow above Antarctica at high altitude (upper troposphere and stratosphere) is dominated by the presence of a vortex centered above the continent. It lasts typically from August to November. This vortex is characterized by a strong cyclonic jet centered above the polar high. In a recent study of our group (Hagelin et al.  2008) of four different sites in the Antarctic internal plateau (South Pole, Dome C, Dome A and Dome F), it was made the hypothesis that the… Expand

A dedicated tool for a full 3D C2N investigation
In this contribution we present how the mesoscale model Meso-Nh model together with the Astro-Meso-Nh and a set of diagnostic tools allow for a full 3D investigation of the C2N and derived integratedExpand


Persistence of the lower stratospheric polar vortices
The persistence of the Arctic and Antarctic lower stratospheric vortices is examined over the period from 1958 to 1999. Three different vortex-following diagnostics (two using potential vorticity andExpand
