Increasing demand on the accuracy of weather and ocean forecasts as well as subseasonal to seasonal (S2S) and climate prediction requires advanced research on the coupled processes between the atmosphere, ocean, land, and hydrology. This session solicits contributions over a range of near-term, S2S, and climate time scales covering topics including but not limited to the study of coupled parameterizations, coupled processes, impacts of coupling, and verification of the coupled atmosphere–land, atmosphere–hydrology, land–hydrology, and ocean–hydrology. Submissions representing both global and regional applications of these prediction systems are encouraged.
