Abstract
  Japanese archipelago exists on the routes of typhoons. Consequently, a lot of typhoons have often raged through the Kyushu district, causing a great deal of damage by storm surges. It is therefore very important to develop an accurate numerical model for storm surge. This study aims to clarify the influences of the time interval of input data, i. e., winds and atmospheric pressures in storm surge simulations. It is shown that the time interval of the input data into a numerical model should be set suitably according to the conditions of each typhoon for accuracy improvement, e. g, the storm surge caused by Typhoon 9918 required shorter input time interval in rapid veering wind condition.
