Welcome
DynVar is an international climate modelling activity that studies the influence of the stratospheric circulation on the global climate system, with a particular emphasis on the two-way dynamical coupling betwen the troposphere and the stratosphere.
The activity promotes the development and use of coupled atmosphere-ocean-seaice general circulation models to ask how does the stratospheric circulation:
- Affect the tropospheric mean climate?
- Impact climate variability on all timescales?
- Impact climate change?
The activity involves scientists from modeling research centres and universities. The activity is open to all researchers interested in contributing; please contact us if you wish to participate.
The DynVar activity is part of the Stratospheric Process and their Role in Climate Project (SPARC). SPARC is a core project of the World Climate Research Program (WCRP).
