- combine elements of the former THORPEX working groups on GIFS-TIGGE and PDP;
- involve both operational and academic communities in scientific research and development challenges;
- provide a centre of scientific expertise on dynamics, predictability and ensemble forecasting that was previously not covered in the core WWRP programme;
- support the WWRP research projects, including the 3 THORPEX legacy projects, S2S, PPP and HIWeather, plus other forecast demonstration projects (FDPs) and research and development projects (RDPs).
The group is chaired by Craig Bishop (NRL, Monterey, USA) and John Methven (University of Reading, UKSarah-Jane Lock (ECMWF) and Laure Raynaud (MeteoFrance), and includes scientific experts from a range of operational and research organizations, including the chair of the the TIGGE panel.
