| 研究実績の概要 |
As written in the "Application Form", the overall objective of this research is to create an advanced weather routing system (AWRS) based on a numerical simulation model of the meteorological and marine phenomena that have strong effects on maritime transport vessels.
As the first-year plan written, the first part of the AWRS should be built by mastering numerical estimation of meteorological and marine phenomena as well as learning the ship motion theory EUT (Enhanced United Theory).
In the past one year, the Multi-Scale Simulator for the Geoenvironment (MSSG) model and RIOS system has been studied and one journal paper titled "Numerical Study of the Small Vessel Navigation in Strong Ocean Current" has been submitted, which can be seen as the first step for the construction of the AWRS.

理由
As that written in the application form, there are two objectives in my first-year plan.
As the first one, constructing the first part of advanced weather routing system by mastering numerical estimation of meteorological and marine phenomena has been tried by using the Multi-Scale Simulator for the Geoenvironment (MSSG) model developed by the “Japan Agency for Marine-Earth Science and Technology” has also been applied for the generation of weather and ocean information at global scale.
As the second one, learning the ship motion theory has also been challenged by studing the EUT (Enhanced United Theory) developed by Prof.Kashiwagi as well as its application in the RIOS (The Research Initiative on Oceangoing Ships) system.
Additionally, the optimization algorithm has also been challenged.

| 今後の研究の推進方策 |
As planed, the improvement of the advanced weather routing system (AWRS) by making proposals concerning new environmental policies such as global warming countermeasures and environmental impact and risk assessment should be focused on in the second year. Therefore, both parts of " prediction of oil spill, ballast water and gas emissions influence area by using global weather and ocean circulation models" and "route optimization based on ship motion calculation and the recommended shipping routes, alternate safer routes" will be challenged.
As the basis, the ship motion, which plays an important role in the AWRS, will be paid more attention to then planed because the present laboratory could provide me such a learning and discussion environment.
