Call for abstracts

The JSC/CAS Working Group on Numerical Experimentation (WGNE) is organising a workshop on systematic errors in weather and climate models to be hosted at the Met Office, Exeter, UK, during 15-19 April 2013.

Submission of abstracts for this workshop are now requested at http://www.metoffice.gov.uk/conference/wgne2013 with a closing date of 31 October 2012. All studies aimed at understanding and reducing systematic errors in general circulation models are welcome. This includes work at any timescale from short range NWP through to multi-centennial climate simulations (and all timescales in between). Of special interest will be studies that consider errors found in multiple models and errors which are present across timescales. 'Top-down' understanding of biases through diagnostic techniques and 'bottom-up' model improvements from process models/observational constraints are both welcome, and biases in the atmosphere, land surface, ocean and cryosphere are all of interest. Work looking at model errors in the following areas are within the scope of the meeting (this list is not exhaustive):

* Tropical processes (Convective processes, MJO, ENSO, AEWs, tropical cyclones, etc.)
* Mid-latitude processes (Evolution of synoptic features, storm tracks, blocking, etc.)
* Sea ice and polar processes
* Clouds, aerosols and radiation
* Land surface processes
* Ocean processes and ocean-atmosphere interactions
* Stratospheric processes and stratosphere-troposphere interactions
* Holistic model evaluation and metrics

In addition to presentations from submitted abstracts, the following invited speakers have been confirmed:

* Leo Donner (GFDL) "Biases and errors in physical parametrizations: New issues raised by first-generation treatments of cloud-aerosol interactions in GCMs"

* Beth Ebert (CAWCR) "New approaches for evaluating NWP"
* Josh Fisher (JPL) "The land surface within climate models: Development and benchmarking of physical processes"
* Julian Heming (Met Office) "Model biases in the simulation of tropical cyclones - NWP to climate"
* Marika Holland (NCAR) "Polar processes and the ability of models to represent them"
* Brian Hoskins (Imperial College) "Mid-latitude blocking"
* Thomas Jung (AWI) "Polar processes and their representation in climate models"
* Bill Large (NCAR) "Serendipitous impacts of ocean parametrizations on coupled model biases"
* Sean Milton (Met Office) "Coupled Ocean-Atmosphere Interactions in NWP"
* Sonia Seneviratne (ETH) "Land surface processes and the ability of models to represent them"
* Ted Shepherd (University of Reading) "Systematic errors in model representation of stratosphere-troposphere coupling"
* Graeme Stephens (JPL) "Using satellite observations to evaluate cloud processes in models"
* Heini Wernli (ETH) "Forecast errors associated with mid-latitude weather systems"
