DynVarMIP

The Dynamics and Variability Model Intercomparison Project (DynVarMIP) is an endorsed participant in the Coupled Model Intercomparison Project Phase 6 (CMIP6) of the World Climate Research Program (WCRP).

DynVarMIP emerged from the Stratosphere-Troposphere Process and their Role in Climate Project (SPARC) DynVar activity on the modelling of the dynamics and variability of the stratosphere-troposphere system. SPARC is a core project of WCRP.

Rather than proposing new experiments, the DynVarMIP requests additional model output from existing CMIP6 experiments. This additional output is critical for understanding the role of atmospheric dynamics in past, present and future climate.

The rationale and the diagnostics proposed by DynVarMIP are presented in Gerber and Manzini (2016).

Models

DynVarMIP promotes 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.

Experiments

DynVarMIP targets the DECK experiments AMIP, Pre-industrial control, abrupt4xCO2 and 1pctCO2, the CMIP6 historical and the ScenarioMIP RCP8.5 experiments, as well as selected experiments within VolMIP, AeroChemMIP, and HiResMIP, where there is natural overlap in scientific interest. 

Diagnostics

Dynvar has established a set of diagnostics  (Gerber and Manzini GMD 2016) to enable a mechanistic approach to confront model biases and understand the underlying causes behind circulation changes.

Modelling centers will provide the DynVarMIP diagnostics, via CMIP6.
