The 3rd SPARC DynVar Workshop has taken place jointly with the 1st SPARC SNAP Workshop, 22-26 April 2013, in Reading, England, UK.


Assessing and Understanding the Impact of Stratospheric Dynamics and Variability on the Earth System. Gerber et al 2012, Bulletin of the American Meteorological Society


SPARC DynVar Activity Stratosphere-Troposphere Coupling Poster Cluster @ WCRP OSC 2011


SPARC DynVar on CLIVAR Exchange:
Stratosphere-resolving Models in CMIP5
Manzini et al 2011, p29


Modelling promoted by DynVar:

Coupled Global Atmosphere, Ocean and Seaice Models (e.g., climate models or AOGCMs) - with high vertical resolution and location of the model tops above the stratopause.

-> Physical cores of Earth System Models with a well resolved stratosphere.

-> Two-way troposphere-stratosphere dynamical coupling with a comprehensive representation of atmosphere and ocean-seaice interactions and climate processes.

Two international projects are including participants employing high top climate models. Multi-model outputs from high top models will become / is becoming available from:

(1) WGSIP's Stratosphere Historical Forecast Project (SHFP). For a description of SHFP click here and for the participants so far here. Contacts: Amy Butler ( and Adam Scaife (

(2) World Climate Research Programme's (WCRP) Coupled Model Intercomparison Project Phase 5 (CMIP5). For a description of CMIP5 and how to access data click here. High top models participating to CMIP5 so far are listed here.

In support of the forthcoming AR5 IPCC assessment, SPARC DynVar encourages the execution of the WCRP's CMIP5 runs with "high top models", and their analysis with in focus the role of statospheric dynamical processes, see Research Topics & Groups.
