Hirose, Application of the ensemble Kalman filter to atmosphere-ocean coupled model, IEEE, 10.1109/NSSPW.2006.4378835, 125 - 128 , 2006.12, [URL], We report the first application of the ensemble Kalman filter (EnKF) to an intermediate coupled atmosphere-ocean model by [1], into which the sea surface height (SSH) anomaly observations by TOPEX/POSEIDON (T/P) altimetry are assimilated. Smoothed estimates of the 54,403 dimensional state are obtained from 1981 observational points with 2048 ensemble members. While data assimilated are SSH anomalies alone, an ensemble experiment of 2002/03 El Niño event based on the EnKF can predict consistent Niño 3 sea surface temperature (SST) anomalies about 5 months in advance..

Togawa, Oil spill simulation in the Japan Sea, WITPress, 10.2495/CENV060261, 88, 273-278, 2006.01, [URL], An assessment system of the marine environment in the Japan Sea is being developed at the Japan Atomic Energy Agency. This study aims to confirm the validity of the assessment system by reproducing the oil spill at the incident of Russian tanker Nakhodka in January 1997. As a main subject, one of the data assimilation techniques, an approximate Kalman filter, was applied to the assessment system by combining an ocean general circulation model with sea level measurements of satellite data. Using calculated ocean currents, simulations of the behaviour of spilled oil were performed with a particle random-walk model. A number of experiments with different parameters and situations showed that the assimilated daily ocean currents with wind drift were for the simulation for movement of spilled oil..

Application to the tanker `Nakhodka' 1997 incident
, Computational Mechanics Publ, 359-370, 1998.07, An operational system for the prediction of oil spills in the Sea of Japan is developed. The modelled climatological sea currents were generated by the three-dimensional primitive ocean circulation model with 10-minute horizontal resolution and 19 vertical levels. The model was forced by climatological atmospheric winds and heat fluxes. The oil spill was modelled with the particle tracking techniques. The model included the advection by currents, random diffusion, buoyancy effect and the parameterization of oil evaporation, biodegradation and beaching. The realization of the model is the real-time simulations and forecasts of the ocean currents with the fine resolution in the upper layer of the Sea of Japan..
