Description
The goal of DynVar is to assess the impact of the two-way dynamical coupling between the stratosphere and the troposphere on surface climate, by using comprehensive atmospheric general circulation models (AGCMs) coupled to ocean general circulation models (OGCMs) as the principal tools of investigation. The use of simplified models and more theoretical approaches to build the understanding of the stratosphere-troposphere coupling is aslo an important component of DynVar. The funding ideas of DynVar are described in two SPARC Newsletters: Kushner et al. 2007 and Kushner et al. 2009.
To pursue its goal, DynVar is expected to focus and facilitate research on the data sets that will be produced for assessment purposes, such as the high-top CMIP5 runs, and the stratospheric seasonal prediction hindcasts produced as part of WGSIP's Stratosphere Historical Forecast Project (SHFP) with high-top models, as well as the CCMVal2 runs.
The activity includes "Analysis Areas" that represent broad themes under which research contributing to the DynVar goal is grouped. On this website, you can access information about the Analysis Areas and the Simulation Sets by following the links on the sidebar. If you wish to participate in the activity, please contact us.
DynVar has links with other ongoing projects, including the CCMVal and SOLARIS activities of SPARC, and the C20C and SHFP of CLIVAR.
