Unusually High Mean Sea Level in September 1971 Along the South Coast of Japan -3. Numerical Experiments on the Unusual High Sea Level along the South Coast of Japan-

Abstract

This study aims to simulate the unusual rise of sea level in September,1971, by the barotropic motion on the continental shelf to the south of Japan based on storm surge equations. We chose two numerical models. In the first model, we only considered the effects of Typhoon 7123. In the second model, the approach of the Kuroshio axis was taken into account. Results of computations show that the long-lasting rise of sea level is only possible in the second model. T he continental shelf wave moving to the west was also simulated in that model.
