The Met Office runs a wide variety of operational marine models, from waves to storm surge to ecosystems. These generate products for a variety of customers and partners including other national meteorological services, environment agencies, the UK navy, and the Copernicus Marine Environment Monitoring Service. This presentation will give an overview of the activities and outputs of the Met Office's Ocean Forecasting Research and Development group. It will then focus on the storm surge forecast system in particular, describing the current system as well as research activities aimed at improving forecasts in the future.
