Propagation of storm surge in a coupled bay system
Author :
An extraordinary high tide was induced by a storm surge in the Mikawa Bay, Japan, caused by a typhoon in October 2009. One of the unique and important characteristics of the storm surge is a sudden sea level rise of 2m in only one hour, which occurred after the Typhoon passed over. In this paper, generation mechanism of such a large sea level rise and dynamics of the surge is discussed using the ADCP current data obtained during the storm as well as the tide and wind records at the observation stations around the bay. The wavelike behaviour of the surge indicates that the main cause of the sudden sea level rise may be attributed to the propagation of water mass form Ise Bay triggered by the sudden change in wind direction.
