| Outline of Final Research Achievements |
An ensemble Kalman filter using a regional mesoscale atmosphere-ocean coupled model was developed to provide realistic sea surface temperature (SST) estimate and to represent the uncertainties of SST in ensemble data assimilation strategies. The newly developed coupled data assimilation system with a simple mixed-layer model was applied to the case of Typhoon Lionrock in 2016. It was found the coupled system with SST data derived from the Himawari-8 showed positive impacts on the TC track and intensity forecasts. The results indicates the usefulness of the regional mesoscale atmosphere-ocean coupled data assimilation system.
