Abstract
High sea levels with time scale more than one week appear sometimes along the Pacific coast of West Japan when the meteorological conditions are rather gentle. If the phenomena appear associated with the spring tide in late summer or early fall, the sea water floods over the land at some places on the coast.
In this paper, eight cases of the h igh sea level selected from the tide records of five years from 1964 to 1968 and one case in September 1971 are investigated in connection with meteorological and oceanic conditions.
The high sea level considered here is not the so-called “storm surge” caused directly by meteorological disturbances. It may be due to the variation of the Kuroshio which is induced by some meteorological conditions. The slow westward propagation of phase of the high sea level may be explained by considering the continental shelf waves.
