ANALYSIS OF WAVE CLIMATE CONDITIONS AT THE ENTRANCE OF ISE BAY USING MEASUREMENT DATA AND HINDCAST DATA

Abstract

This paper deals with the estimation of wave climate conditions at the entrance of Ise Bay which have not been extensively investigated. First, based on the statistical analyses of wind and wave data measured over several years at 3 buoy stations, climatic conditions of winds and waves at the entrance area are discussed. Next, a long term wave hindcast system on a nested grid with high space resolution of 1 km is applied location by location under 20-year ECMWF and 51-year NCEP/NCAR surface wind data conditions. Findings are that the system reproduces well the wave climate condition evaluated from the measurement data at each of the 3 stations and that any wave height climate parameter does not indicate an increasing or decreasing trends with statistical significance over the recent 41-year period.
