TL;DR: The forecast skill on subseasonal scales showed a much-improved prediction of the Madden-Julian Oscillation in GEOS-S2S-2, and on a seasonal scale the tropical Pacific forecasts show substantial improvement in the east and comparable skill to GEos-S 2S-1 in the central Pacific.

Yoo-Geun Ham,Yoo-Geun Ham,Michael M. Rienecker,Max J. Suarez,Yury Vikhliaev,Bin Zhao,Jelena Marshak,Guillaume Vernieres,Siegfried D. Schubert +8 more
TL;DR: In this article, a suite of decadal predictions has been conducted with the NASA Global Modeling and Assimilation Office's (GMAO) GEOS-5 Atmosphere-Ocean general circulation model.

TL;DR: In this paper, the authors document the characteristics of the GEOS-5 seasonal forecast system and highlight forecast biases and skills of selected variables (sea surface temperature, air temperature at 2 m, precipitation and sea ice extent) to be used as a benchmark for the future GMAO seasonal forecast systems and to facilitate comparison with other global seasonal forecasting systems.
