Journal ArticleDOI
SEAS5: the new ECMWF seasonal forecast system
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.
Journal ArticleDOI
The resolution sensitivity of the South Asian monsoon and Indo-Pacific in a global 0.35° AGCM
Stephanie J. Johnson,Richard C. Levine,Andrew G. Turner,Gill Martin,Steven J. Woolnough,Reinhard Schiemann,Matthew S. Mizielinski,Malcolm J. Roberts,Pier Luigi Vidale,Marie-Estelle Demory,Jane Strachan +10 more
TL;DR: In this paper, the authors used 27-year integrations of a high-resolution atmospheric general circulation model (Met Office Unified Model) to study changes in South Asian monsoon precipitation and circulation when horizontal resolution is increased from approximately 200-40 km at the equator (N96-N512, 1.9°-0.35°).
Journal ArticleDOI
An assessment of Indian monsoon seasonal forecasts and mechanisms underlying monsoon interannual variability in the Met Office GloSea5-GC2 system
Stephanie J. Johnson,Stephanie J. Johnson,Andrew G. Turner,Steven J. Woolnough,Gill Martin,Craig MacLachlan +5 more
TL;DR: In this paper, the authors assess Indian summer monsoon seasonal forecasts in GloSea5-GC2, the Met Office fully coupled subseasonal to seasonal ensemble forecasting system.
Journal ArticleDOI
How confident are predictability estimates of the winter North Atlantic Oscillation
Antje Weisheimer,Antje Weisheimer,Damien Decremer,David MacLeod,Christopher H. O'Reilly,Timothy N. Stockdale,Stephanie J. Johnson,Tim Palmer +7 more
TL;DR: In this paper, seasonal hindcasts of the ECMWF model for the recent period 1981-2009 show that correlation skill over Greenland and parts of the Arctic is higher than the signal-to-noise ratio implies.
Journal ArticleDOI
The northern hemisphere circumglobal teleconnection in a seasonal forecast model and its relationship to European summer forecast skill
Jonathan D. Beverley,Steven J. Woolnough,Laura Baker,Stephanie J. Johnson,Antje Weisheimer,Antje Weisheimer +5 more
TL;DR: In this article, the authors assess the performance of a seasonal forecasting model at representing a major mode of northern hemisphere summer climate variability, the circumglobal teleconnection (CGT), and the implications of errors in its representation on seasonal forecasts for the European summer (June, July, August).
