Workshop on sub-seasonal predictability

The workshop on sub-seasonal predictability was held at ECMWF on 2-5 November 2015.

Workshop description

The workshop will provide an opportunity to review recent advances and future challenges in sub-seasonal prediction in coordination with the WCRP-WWRP Sub-seasonal to Seasonal (S2S) Prediction Project. Topics  that will be discussed include sources of sub-seasonal predictability (Madden-Julian Oscillation, stratospheric initial conditions, soil moisture, snow, sea-ice, sea surface temperature), and diagnostics and skill of operational forecasts. Working group discussions will be organised around three themes: physical processes (including model uncertainty simulation), forecast system/model design (including the definition of ocean-land-atmosphere initial conditions, ensemble generation methods, forecast length) and international multi-model efforts and collaborations.
