| Outline of Final Research Achievements |
Optimal operation of ships is required on a basis of accurate forecast against complicated weather conditions. A technology of weather forecast has been developed in a recent decade, however, it is found that the wave pattern is difficult to reproduce when low pressures move northeasterly from southern sea area of Japan. In this study, two examples are simulated when the ferry navigates in the Pacific Ocean and encounters larger waves against the forecasted values. Regional models of air and ocean, WRF and SWAN, is used to clarify the factor which makes difficult to forecast. It is necessary to define the simulation area and resolution for low pressures in each case, and correction of wave energy needs in some cases. The total measurement of ship performances and weather conditions is constructed, and has measured continuous situations. These will be used for the improvement of accuracy about the correction of wave energy in numerical simulation models.
