A general introduction to UU-CM

Traditional atmospheric, oceanic and wave models are run independently with each other. Many air-sea interaction processes cannot be captured in stand-alone models. Building a seamless model, which can capture the physical air-wave-sea-ice interaction processes more accurately is important for weather and climate research.   Accordingly, a seamless coupled model is an important tool for studying various atmospheric and oceanic processes on different scales.

Uppsala University-Coupled Model (UU-CM) is a state-of-the-art atmosphere-wave-ocean-ice regional coupled model, which includes four components, atmosphere (WRF), ocean and ice (NEMO), and waves (WaveWatch-III). The coupler, OASIS3-MCT, is used for the information exchange between sub-components. Different from traditional coupled models, more physical air-wave-sea/ice interaction processes have been introduced into UU-CM, such as, Stoke drift, sea-state-dependent momentum flux (in both atmosphere and ocean sides), wave-ice interactions, etc. The UU-CM model is an important tool for studying different air-sea interaction processes, extreme events, etc.
