  2. Background WWRP THORPEX ends in 2014 WMO EC June 2012: Two new WWRP Projects S2S: Subseasonal to Seasonal PPP: Polar Prediction Project THORPEX ICSC October 2012: Identified potential need for additional project What is missing? High Impact Weather plays important role in S2S and PPP But S2S does not cover issues related to improving predictions of High Impact Weather on minutes-to-weeks time scales PPP focussed on specific geographical region Proposal for a 5-10 year WWRP High Impact Weather Project
