UFS will address forecast applications across scale ranging from tornadoes to El Nino. To accomplish these goals requires forecast systems that couple the global atmospheric model with models, for example, of the ocean and coastal storm surge. Within the UFS activities, coupled model applications are being tested for atmospheric chemistry, wave-storm surge interactions, ocean-sea ice interactions, and sub-seasonal to seasonal forecasting. Coupled forecast models are essential for the sub-seasonal to seasonal forecast products, and they have been shown to have important impacts on global weather for time spans of less than 10 days. Another important goal of the UFS activity is to improve forecast skill of thunderstorms and tornadoes. The new global atmospheric model, FV3-GFS, has the ability to improve the representation of these scales. There is a limited area regional version of FV3-GFS. There is active experimentation with cloud and boundary layer schemes. Already, these storm-scale experiments show a path forward to a simplification of the forecast systems and more accurate forecasts.
