| Abstract;There are many kinds of the aquatic invasive species in Tokyo Bay and most of the species seems to be carried by the ballast water in ocean going ships. The floating larvae of aquatic invasive species are released with the ballast water around the ports. Some of released species are able to thrive around the ports and cause disruptions in the natural ecosystem. The present study focuses on the dispersion process of the floating larvae of aquatic invasive species released at Port of Yokohama. In particular, the wind effect on the process is discussed by Random-Walk Particle-Tracking analyses in this paper. A quasi-3D baroclinic flow model is applied to simulate the current system and the density field. The present model can predict well the seasonal flow and density structures in Tokyo Bay which were observed at monitoring stations. The distribution of released particles is changed temporally by the tide and the wind effect. The results of numerical simulation show the sea areas at where the aquatic invasive species may arrive.
