3. CASXV on WWRP The Commission acknowledged the general increase in the activity levels of the WWRP … and the numerous successes of the programme  ……. agreed that the completion of the first Strategic Plan for the Implementation of WMO’s World Weather Research Programme (WWRP): 2009–2017 (WMO/TD-No. 1505) was a milestone and a significant contribution to meeting the Expected Results of the WMO Strategic Plan  ……. concurred with general directions outlined in the WWRP Strategic Plan and noted that the document fulfilled the design of the programme as decided upon at CAS-XIV.  Forecast Demonstration Projects (FDPs) in the MAP D-PHASE Project for flash flooding in Alpine regions and the Beijing 08 effort that focused on convection and severe weather  Research and Development Projects (RDPs) including MAP, the Beijing 08 RDP, TCS-08, and COPS

4. CASXV on WWRP continued The Commission acknowledged the general increase in the activity levels of the WWRP … and the numerous successes of the programme  Involvement in training and publishing of reports and documents of community interest both as WMO Technical Documents and in the Scientific Literature  The development of web-based user tools that are widely used by the community including forecasting verification tool set  The participation of the WWRP in cross-cutting efforts such as forecast verification and the Sand and Dust Storm Warning Advisory and Assessment Project;  Further scientific advancements in various aspects of data assimilation, coupled hydrological modeling for flooding, ensemble prediction, convection, tropical cyclones and monsoons, orographic effects, mesoscale meteorology, and verification techniques  A variety of workshops, conferences, training sessions, and symposium.

5. CASXV on WWRP-THORPEX ………… agreed that THORPEX has contributed substantively to the advancement of Members needs and fostered a tremendous sense of partnership and collaboration around the world particularly through the following activities:  Completion of three major field experiments, A-TREC, E-TREC and T-PARC with its two experimental phases  Activities to address regional prediction needs, such as the assessment of targeted observations for extra-tropical and tropical cyclones, THORPEX Africa, and THORPEX involvement in the assessment of the forecast impacts of additional observations over Africa taken as part of the AMMA Project  The development and execution of the IPY-THORPEX cluster of projects focused on advancing numerical weather prediction for polar regions;  The development of the TIGGE database as a major community resource with model  Initiation of the Year Of Tropical Convection (YOTC) Project

6. New projects Sub-seasonal to Seasonal Prediction – “….the Commission requested the JSCs of the WWRP and the WCRP and also the THORPEX ICSC to set up an appropriate collaborative structure to carry out an international research initiative on sub-seasonal to seasonal forecasting. It recommended that this is closely coordinated with the present existing CBS infrastructure for long- range forecasting (with centres producing long-range forecasts and regional climate centres) and with the future developments in WMO climate service delivery and the Global Framework for Climate Services called for in the High-Level Declaration of WCC-3.” Polar Prediction project – “The Commission concurred with the Executive Council Panel of Experts on Polar Observations, Research and Services on the requirement for effective collaboration and therefore recommended that any efforts to develop a future prediction system include outcomes from the IPY-THORPEX cluster of projects and from the planned THORPEX Legacy Project”

7. Leadership of WWRP and THORPEX  CASXV established a new WWRP/JSC with a membership of ten independent scientists  Appointed the Chairs of the WWRP and the THORPEX Working Groups as ex-officio members of the new WWRP/JSC  Fourth meeting of the WWRP/JSC – 21 to 24 February 2011 in Geneva
