Ziel
To investigate the current capabilities of General Circulation Models to correctly model the atmospheric circulation from the surface and up to the stratopause, with special attention to the middle atmosphere, and to investigate the role of stratospheric circulation in tropospheric climate and climatic variability.
The current GCMs will be documented, and these descriptions will be kept updated in the light of improvements
made to the models. Middle atmosphere and stratospheric datasets will be assembled and will be compared and
documented.
The GCMs will be compared to identify common systematic errors and differences between them. The
climatological mean states, quasi-stationary and transient waves will be compared and documented, and a
number of specific aspects of the middle atmospheric circulation will be studied in detail: The thermal structure
of the polar lower stratosphere, the tropical quasi biennial and semiannual oscillations.
A number of specific analyses will be performed relating to the evolution of stratospheric warming events, the
linking of stratosphere and troposphere, and the modes of variability, including circulation indices, EOFs and
teleconnections.
The models parametrisation schemes will be evaluated with a view to assess their influence on the models
systematic errors, and improved parametrisations will be developed and tested. An important part is the
documentation of improvements obtained and their consistency between the models. A special study will be
devoted to the intercomparison and improvement of the radiation codes.

project within the 'Stratospheric Processes and their Role in Climate' (SPARC) programme of the WCRP.
