Information - AS1.17 Structure, dynamics and composition of the extratropicaltropopause region
Event Information
This session focuses on the structure of the extratropical tropopause region.
We invite observational as well as model based contributions that look at
chemistry, dynamics and thermodynamics in that region.
This includes investigations of tracer transport and STE, the structure of the
tropopause region, and the impact of the tropopause region on tropospheric
climate and chemistry.
Particularly welcome are papers that combine recent in-situ or remote sensing
observational data sets with model based investigations or output from
chemistry climate models adressing one of the following aspects:
1. Composition of the extratropical upper troposphere/lower stratosphere,
relevant transport processes and underlying time scales for transport and
mixing.
2. Structure of the extratropical tropopause, including de nitions of the
tropopause (chemical, thermal and dynamical), and processes important for
tropopause formation and maintanance.
3. Interactions between composition (chemistry) and tropopause structure.
4. Variability and change of the tropopause region, including seasonal, interannual
and long term changes of the tropopause region and the role of the
extratropical tropopause region in global climate and climate change.
