The Year of Polar Prediction (YOPP) Summit, a major event in the further planning of the Year of Polar Prediction, was held from 13–15 July 2015 at WMO headquarters in Geneva, Switzerland. The Summit was attended by 116 participants from 20 different nations including scientists, stakeholders, as well as representatives from operational weather and climate prediction centres, international bodies and funding agencies. Live streaming of the plenary sessions turned out to be very popular with up to 750 users online at the same time. After welcoming statements by WMO representatives and the chair of the WWRP Polar Prediction Project (PPP), the Summit started with background presentations on the strategic relevance of enhanced polar predictive capacity and the present level of planning as outlined in version 1.0 of the YOPP Implementation Plan1.
This was followed by a series of plenary panel presentations and open discussions in sessions covering each of the following key YOPP themes:
- User-relevant aspects
- YOPP observing component
- YOPP modelling, data assimilation and forecasting component
- YOPP data component
- YOPP education and outreach component
Subsequently, a total of 26 representatives from partners such as international programmes, institutions and space agencies presented their expectations of YOPP, made suggestions on how they could contribute, and formulated specific recommendations to improve the programme. As part of the post-Summit process, the different commitments will be gathered and an endorsement process will be developed. The partner presentations were followed by discussions and formulation of recommendations in breakout groups (BOG) for each of the above-mentioned YOPP key areas along with the additional topic of YOPP funding. The Summit finished with a plenary session that included statements from funding agencies, the presentation of BOG reports, and a general discussion on major issues and actions required to further the programme. These and other outcomes of the Summit will be used to update the YOPP Implementation Plan (from version 1.0 to 2.0) in northern autumn 2015. The Summit was closed following a short wrap-up and a brief overview of the next steps including an outline of the postSummit process. Throughout the remainder of the report, the key outcomes of the YOPP Summit will be briefly summarized and links to relevant documents will be provided. Several YOPP-related outcomes and issues were further deliberated during the 6th meeting of the PPP steering group (PPP-SG6 hereafter) held immediately after the Summit from 15–16 July 2015—relevant decisions from PPPSG6 and implications for YOPP are noted in the text.
