AS1.9

With the advent of the sub-seasonal to seasonal (S2S) prediction project, research communities now have unprecedented access to a comprehensive database of forecasts and hindcasts from a large number of forecasting centres from across the globe.

This session invites contributions that span all aspects of meteorological/oceanographic prediction in the 2 weeks to 2 months lead time range. The session will include both meteorological and impacts studies, that may use the S2S project’s database, but that can also use alternative sources of forecast information. Contributions are welcome for studies of phenomena such as the Madden Julian Oscillation (MJO), tropical/extratropical waves, stratospheric variability and stratosphere - troposphere coupling, in addition to studies of predictability/skill of atmospheric or surface variables and case studies of high impact weather events.

Contributions regarding impacts studies at the S2S time-range are also highly welcome, including, but not limited to, the areas of hydrology, health, fire, agriculture, and energy. These can include modeling studies of the impacts right through to presentations of how S2S-derived information can be integrated into decision support systems at the local, regional and country level.
