摘要：Public expectations have been set for the development of skillful meteorological forecasts of unprecedented leads out to a month or two; filling the so-called subseasonal to seasonal prediction gap. While both the weather and climate communities; coordinated internationally by the World Weather Research Programme (WWRP) and the World Climate Research Programme (WCRP); respectively; can contribute to address this challenge; neither of them can effectively meet the challenge alone. The WWRP/WCRP Subseasonal to Seasonal (S2S) Prediction Project and related initiatives such as the Modeling; Analysis; Predictions and Projections (MAPP) Program S2S Prediction Task Force are providing a framework for needed weather–climate community interactions. Such joint weather–climate efforts need to be sustained in the future for continued progress in subseasonal to seasonal prediction.
