Stephanie J. Johnson,Timothy N. Stockdale,Laura Ferranti,Magdalena Balmaseda,Franco Molteni,Linus Magnusson,Steffen Tietsche,Damien Decremer,Antje Weisheimer,Gianpaolo Balsamo,Sarah Keeley,Kristian Mogensen,Hao Zuo,B. M. Monge-Sanz +13 more
TL;DR: SEAS5 as discussed by the authors is the ECMWF's fifth generation seasonal forecast system, which became operational in November 2017 and includes upgraded versions of the atmosphere and ocean models at higher resolutions and adds a prognostic sea-ice model.

TL;DR: In this article, a multi-reanalysis ensemble is used to estimate the signal-to-noise ratio (SNR) of the ocean state and to estimate uncertainty levels.
Journal ArticleDOI
A review on Arctic sea‐ice predictability and prediction on seasonal to decadal time‐scales
Virginie Guemas,Edward Blanchard-Wrigglesworth,Matthieu Chevallier,Jonathan J. Day,Michel Déqué,Francisco J. Doblas-Reyes,Neven S. Fučkar,Agathe Germe,Ed Hawkins,Sarah Keeley,Torben Koenigk,David Salas y Mélia,Steffen Tietsche +12 more
TL;DR: A review of the potential sources of Arctic sea-ice predictability on these time-scales is presented in this paper, where the inherent potential predictability limit with state-of-the-art models is estimated, together with their performance.
Journal ArticleDOI
Improved Atlantic winter blocking in a climate model
Adam A. Scaife,Dan Copsey,Chris Gordon,Chris Harris,Tim Hinton,Sarah Keeley,Alan O'Neill,Malcolm J. Roberts,Keith D. Williams +8 more
TL;DR: In this paper, the authors show greatly improved simulations of Atlantic winter blocking frequency in a coupled ocean-atmosphere climate model, due to an improved simulation of the Atlantic Ocean, is a key element of the improvement.
