On the Variations of the Daily Mean Sea Levels along the Japanese Islands

Abstract

The variations of the daily mean sea levels at 22 tide stations along the Japanese coast and their relations to the oceanographic and meteorological phenomena were examined. It was found that the variations are closely related to the oceanographic conditions,

Sea-Level Rise and Land Subsidence: Impacts on Flood Projections for the Mekong Delta’s Largest City

“…Abnormal high tides induced by such mechanisms have been investigated on various coasts across the world. For instance, Shoji [31] demonstrated, using the data from 22 tidal stations in Japan, that the daily mean sea levels move along the coast. Such traveling means waters could be separated into two types of waves, namely internal Kelvin-type waves and continental shelf waves [32].…”

Coastal Disturbance in Sea Level Propagating along the South Coast of Japan and Its Impact on the Kuroshio

“…Westward propagation of peaks in sea level along the southern coast of Japan was found by Shoji (1961) and Isozaki (1969). The propagation occurs in the variations of sea level for periods shorter than 10 days, especially for 4-6 days (Nagano and Kawabe, 2004).…”

“…A candidate for the other factors in the third category may be a coastal disturbance propagating westward. Shoji (1961) and Isozaki (1969) reported a westward propagation of sea level along the southern coast of Japan. The propagation occurs in sea level variations for periods shorter than 10 days, especially for 4-6 days (Nagano and Kawabe, 2004).…”

An Investigation on the Variations of Sea Level due to Meteorological Disturbances on the Coast of Japanese Islands (II)

“…SHOJI (1961) presumed that this might be a kind of internal Kelvin wave induced by an (41) atmospheric disturbance.…”

“…SHOJI (1961) suggested that this wave might be an internal Kelvin wave induced by a progressive typhoon, but he could not sufficiently verify validity of the assumption because of scantiness of observed data.…”
