黒潮フロントヘの海底地形の力学的影響

Abstract

Dynamical effect of bathymetric profile pattern to Kuroshio front is studied on the bases of a theoretical solution and an observed data of the satellite thermal patterns. A front off a semifinite ocean is assumed. A subsurface bathymetric pattern is taken as an exponential cross-section vertically. Some mathematical technique is used for obtaining a final solution. Variations of the considering front just around the bathymetric pattern with some parameters. Several satellite thermal patterns can be realized referring to the theoretical solution. This result may help to promote at warning and protection for the storm surges and tsunamis.
