ON KUROSHIO AS ONE OF FACTORS FOR STORM SURGE HAZARDS IN THE KINKI COASTAL ZONE

One of the major research projects at the Shirahama Oceanographic Observatoryis observation of storm surges in relation to coastal hazards. Recent needs are tomeasure offshore properties of waters affected by storms and to find a pertinentway of storm surge prediction in order to help coastal disaster prevention. Thisreport is for a problem on Kuroshio as one of factors related to storm surge hazardsin the Kinki coastal zone. At first, the author remarks about a shift of the Kuroshi-o meandering after passage of the Typhoon 8506. Kuroshio meandering is studiedin relation to the observed results at the Shirahama Oceanographic Tower as an off-shore fixed station during stormy and calm days. Lastly, it is notifyed that the Ty-phoon 8719 shifted the Kuroshio flow to the north during the passage and that ther-mal energy transfer from the sea water to the air through the sea surface causedpossibly the sea surface temperature decrease off the south of the Kinki coastalzone. This thermal effect must be effective to maintain the Typhoon which hadbrought an additional heavy rain around its track.One of the major research projects at the Shirahama Oceanographic Observatoryis observation of storm surges in relation to coastal hazards.
