JSC/CAS Working Group on Numerical Experimentation (WGNE)

WGNE is supporting numerical experimentation research activities of the

WMO/ICSU/IOC-UNESCO World Climate Research Programme (WCRP)
WMO World Weather Research Programme (WWRP)
WMO Global Atmosphere Watch Programme (GAW) as well as research links to operational weather and climate prediction.
WGNE Madden Julian Oscillation (MJO) Task Force (TF)

The Working Group on Numerical Experimentation (WGNE), jointly established by the WCRP Joint Scientific Committee (JSC) and the WMO Commission for Atmospheric Sciences (CAS), which is responsible for WWRP and GAW, has the responsibility of fostering the development of atmospheric circulation models for use in weather, climate, water and environmental prediction on all time scales and diagnosing and resolving shortcomings (WMO/TD 121). WCRP-JSC/CAS WGNE promotes co-ordinated numerical experimentation for validating model results, observed atmospheric properties, exploring the natural and forced variability and predictability of the atmosphere, (e.g. the Atmospheric Model Intercomparison Project, AMIP), as well as studies aimed at refining numerical techniques, and the formulation of atmospheric physics processes. WGNE also monitors the advances in data assimilation and analysis methods and is the focal point in the WCRP for encouraging and reviewing the reanalysis projects carried out at various centres with fixed state-of-the-art assimilation systems providing a multi-year homogenous data set for a range of atmospheric and climate diagnostic studies (log-in to the password protected WGNE website).

Terms of Reference

Advise the JSC and CAS on progress in atmospheric modelling.
Review the development of atmospheric models for use in weather prediction and climate studies on all scales, including the diagnosis of shortcomings.
Propose numerical experiments aiming to refine numerical techniques and the formulation of atmospheric physics processes, boundary layer processes and land surface processes in models.
Design and promote co-ordinated experiments for:
- validating model results against observed atmospheric properties and variations;
- exploring the intrinsic and forced variability and predictability of the general circulation of the atmosphere on short to extended ranges;
- assessing the intrinsic and forced variability of the atmosphere on climate time-scales.
Promote the development of data assimilation methods for application to numerical weather and climate predictions, and for the estimation of derived climatological quantities.
Promote the development of new methods for numerical weather prediction and climate simulation.
Maintain scientific liaison with other WCRP and CAS groups as appropriate.
Promote the timely exchange of information, data and new knowledge on atmospheric modelling through publications, workshops and meetings.
