1 Proposal for a WWRP High Impact Weather Project Sarah Jones, Brian Golding Philippe Arbogast, Ana Barros, Aida Diongue, Beth Ebert, Grant Elliott, Pat Harr, Tim Hewson, Julia Keller, Stefan Klink, Sharan Majumdar, Rebecca Morss, Pierre Pellerin, David Richardson, Peter Steinle, Jenny Sun, Richard Swinbank, Zoltan Toth, Jian Jie Wang, Heini Wernli, Hui Yu THORPEX ICSC July 2013

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

3 Development of Proposal Brainstorming after ICSC-10, Initial proposal to ICSC North American Town Hall at AMS Annual Meeting January 2013 in Austin, TX, USA Initial international workshop to define scope & objectives March 2013 in Karlsruhe, Germany Appointment of task team Chair: Sarah Jones, WMO Consultant: Brian Golding May 2013, 21 Members representing 9 nations/ WWRP & THORPEX WGs First draft of outline proposal End of May 2013 Task Team Telecons to agree on structure and objectives June 2013 Submit draft of proposal to WMO for ICSC/JSC 9 July 2013 Discussion at ICSC / JSC; Agreement on way forward Revise proposal for submission to CAS in November

4 The overall objective of the High Impact Weather project is to: “Promote cooperative international research to achieve a dramatic increase in resilience to high impact weather, worldwide, through improving forecasts for timescales of minutes to two weeks and enhancing their communication and utility in social, economic and environmental applications” Mission of Project

5 Scope of Project Achieve a major advance in the ability of individuals, businesses and communities to reduce adverse weather impacts ● Improve understanding of factors influencing predictability of HIW ● Improve forecast accuracy, resolution and lead time of HIW forecasts ● Relate High Impact Weather forecasts to human impact, taking account of vulnerability ● Reduce impact of High Impact Weather by improving communication

6 Scope of Project Applications: Increase resilience of social, economic and environmental receptors Provide justification Determine key impacts Reap the benefits of research Research programme that responds to the needs of the users for specific weather-related applications

35 External Engagement To-date: knowledge of user requirements present in task team During further development of implementation plan: Engage with national / international bodies that already engage with users During project: meet with end users at variety of levels to define user needs and transfer results

36 Strategies to achieve goals Develop linkages with other initiatives –International bodies and activities, WWRP Working groups, national initiatives, Post-Hyogo activities on disaster risk reduction Strengthen inter-disciplinary linkages between academia, research institutions and oper. centres –Driven by stakeholders who are concerned with the outcome of increasing resilience, carried out in disciplinary groups Engage communication of scientists with different backgrounds through workshops, conferences etc.

37 Strategies to achieve goals Establish and exploit special research datasets – Report additional observations through GTS – Continue TIGGE / TIGGE LAM to foster research activities concerning multi-model ensemble processing Significant results for low probability events require large datasets Interaction and communication with stakeholders – Identify needs of stakeholders, engage them and communicate effectively Support research and demonstration projects – Study communication of forecast, perception of recipients and their actions in the field (T-NAWDEX, Lake Victoria, HYMEX, Severe Weather testbed…)

38 Builds on THORPEX – what is new?
