Edited by the International Coordination Office for Polar Prediction, the PolarPredictNews keep you updated with recent, ongoing and upcoming activities during the Year of Polar Prediction. With this newsletter, we are aiming to build a common platform to exchange information, updates, and developments in polar prediction. Therefore, we are looking forward to your active contributions sharing your topics relevant to the community. Please send any information including announcements you would like to distribute via our newsletter to office@polarprediction.net.

September 2018: PolarPredictNews #08

The #ArcticOcean2018 expedition and thus the YOPP-endorsed ACAS campaign came to a successful end few days ago when the Swedish research icebreaker Oden reached port of Longyearbyen after 50 days at sea. In the new issue of PolarPredictNews, read more about the Oden expedition and what else has happened during the Arctic summer Special Observing Period, or SOP. While the SOP is just about to end, impact of these additional observations can be viewed from the ECMWF website. Also, learn more about three new modelling datasets provided to the polar prediction community, look into newest publications relevant to YOPP, and read about an exciting citizen-science project that took place this summer in the central Arctic Ocean.

Find out about the different channels of communication, not only where you can find further information about YOPP but even place your own announcement to the PPP community. Also, learn about the investments and personnel that are being been made by the many different projects endorsed by the Year of Polar Prediction. PI of the YOPP-endorsed project Arctic Climate Across Scales (ACAS) Michael Tjernström shares his expectations about ACAS measurements that will take place during the upcoming summer's cruise on the Swedish research icebreaker Oden to the North of Svalbard. As well featured is the Sea Ice Prediction Network South initiative (SIPN South) that just released their post-season report on the ability of different models to predict Antarctic sea ice conditions as a test for the Southern Hemisphere Special Observing Period scheduled during the next austral summer season.

Many of you used this spring to meet colleagues at workshops and conferences where YOPP activities were further discussed; read about the YOPP APPLICATE Townhall meeting at EGU in Vienna, Austria, the Polar Prediction Workshop in Montréal, Canada, or the MOSAiC workshop in Potsdam, Germany. Another highlight during spring has been the second Polar Prediction School which took place in April in Northern Sweden.

April 2018: PolarPredictNews #06

Thanks to the many station staff members from 16 Arctic met stations, more than 1,900 extra weather balloons could be launched during the Arctic Winter Special Observing Period. In the new issue of PolarPredictNews, read about the first eight weeks of enhanced routine operations in polar regions to improve weather and sea ice forecasts; find more information about how Arctic warming drives Arctic summer storms; and learn about new Arctic real-time high-resolution atmosphere, ice and ocean forecasts as a contribution by ECCC to YOPP.

Enjoy reading on a scenic perspective about the Arctic Frontiers Science Conference in Tromsø where YOPP together with other projects had organized a topic “The New Arctic in a Global Context” earlier this year. Also, we are happy to announce progress when it comes to gender balance within YOPP: read about a statement on Gender Equality for YOPP that had just been released on the website.

Special thanks goes out to all authors who provided fabulous contributions to this new PolarPredictNews issue.

January 2018: PolarPredictNews #05

How good is environmental prediction in the polar regions? Are there specific weather phenomena which are not yet well represented by numerical models? In this issue, our PPP Steering Group members Barbara Casati and Gunilla Svensson present on their plans to coordinate process-based evaluations using high-frequency multi-variate observations at polar so-called YOPP Supersites to answer these and other questions. 

Further in this issue, read about an updated version of the ‘Sea Ice Information Services in the World’ which provides information on best practices of currently available sea-ice services, and about the World Data Center PANGAEA serving as a YOPP Data Hub.

We like to invite you to learn about two community efforts contributing to YOPP which you can join: the Sea Ice Prediction Network South (SIPN South) has been initiated to assess the ability to forecast sea ice around Antarctica in summer; and the Sea Ice Drift Forecast Experiment (SIDFEx) collects and analyzes Arctic sea ice drift forecasts at lead times from days to a year.

November 2017: PolarPredictNews #04

In the fourth issue of the PolarPredictNews, read about the first YOPP Online Conference which has been well attended and allowed colleagues to get in touch with planned and ongoing activities during YOPP. Zoom into the new YOPP Observations Layer – a great overview of what actually happens during YOPP – to explore extra routine observations starting already in less than three months with the launch of the first YOPP Special Observing Period on February 1st, 2018. Thanks to the many contibuting guest authors, read about a medical evacuation from South Orkney Islands and enjoy the story on the Arctic Circle meeting that recently took place in Reykjavik. Find out how the devastating hurricane Irma even may affect the weather north of Alaska, and learn about the upcoming campaign of the YOPP-endorsed project CAALC to better understand atmospheric characteristics over Antarctica.

August 2017: PolarPredictNews #03

Read in the third issue of the PolarPredictNews about the YOPP Launch that took place in May at WMO headquarters. By the way: Did you know there has been an Italian launch of the Year of Polar Prediction?

Get an update on activities that will take place during the YOPP Special Observing Periods (SOPs), find out how you can apply for the second Polar Prediction School scheduled for April 2018, and don't forget to check out the new YOPP Data Portal. And wait... have you already watched the Polar Prediction video animation?

December 2016: PolarPredictNews #02

Read in the second issue of the PolarPredictNews about the YOPP Task Teams that have been recently formed in order to advance preparations for the Year of Polar Prediction. Find out how you can get involved with the Year of Polar Prediction and make sure to save the dates of the Special Observing Periods (SOPs) that have just been finalized. The SOPs will be carried out to enhance routine observations for several weeks during the Year of Polar Prediction in the attempt to close the gaps in polar observing systems.

Amongst others, learn more about a recently completed international airborne experimental campaign which involved four research aircraft and 584 additional radiosondes to examine the jet stream and its role over Europe and the North Atlantic, and meet with the leader of the YOPP Task Team on Airborne Platforms, Manfred Wendisch, who coordinates a German Transregional Collaborative Research Centre to quantify the contribution of different atmospheric processes causing Arctic Amplification.

October 2016: PolarPredictNews #01

In this first issue of the PolarPredictNews, learn more about a flying laboratory and new colleagues joining the Polar Prediction Steering Group. Read about the preparation of the Year of Polar Prediction in Columbus, Ohio and Reading, UK, and meet with Dave Bromwich chatting about his YOPP-endorsed project in West Antarctica.
