The 30th Session of the GEWEX Scientific Steering Group (SSG) held from at USRA’s Washington, DC office at 425 3rd St, SW, Suite 605, Washington, DC. The meeting of the SSG focus on updating GEWEX’s strategy documents and GEWEX Imperatives to align with WCRP’s new priorities.

Guy Brasseur (WCRP) introduced a WCRP review program outcome. A review panel chaired by Julia Slingo and produced a report (yet to be released) addressed to the sponsor of WCRP (WMO, IOC, ICSU). A February meeting will discuss the report. The program, panels, GCs is thoroughly reviewed and 7 recommendations are drafted. An integrated and seamless with weather, WWRP-WCRP interactions: Processes, variability (minutes to month, seasonal to decadal), human activity response (CO2 and anthropogenic modifications).

The new aim is to be much more Cross-Cutting, Ocean-Atmosphere-Land and embrace human-sphere to develop a new generation of models. The 10-year strategic plan for WCRP aiming at projecting a (punchy) vision done in 2 steps: 1) The strategic plan, with ideas and topics without organisational ties first. 2) An implementation plan 5-year into the future with more logistic aspects.
