Progresses and Challenges for Subseasonal to Interdecadal Prediction

Subseasonal to decadal predictions provide essential information that bridges the gap in timescales between weather forecasts and long-term climate projections. The science and practice of making such predictions using global climate models initialized with observational data has advanced considerably in recent years, and as a result operational subseasonal, seasonal and decadal prediction services are now a reality. Nonetheless, important remaining challenges must be overcome if these predictions are to more fully realize their potential value for society. This talk highlights five key challenges recommended as targets for focused international research; these are set against a backdrop of wider challenges encompassing climate modelling and services across time scales.
