IMPACT ASSESSMENTS OF CLIMATE CHANGE ON STORM SURGES AND HIGH WAVES OF TOSA BAY USING d4PDF

Abstract

 In order to use d4PDF for future predictions in storm surges and high waves due to the climate change, it is required to develop a practical method to utilize a huge amount of data. In this study, we analyzed wave climate in the Tosa Bay by using d4PDF typhoon track data in future +4K environment. The wind speed due to the future typhoons was found to be underestimated by the existing relationship between the atmospheric pressure and wind fields. Corrections for the wind speed were therefore necessary to estimate wave climate appropriately. We also confirmed that waves and surges in the Tosa Bay were highly sensitive to the pattern of SST. Therefore, it is important to keep a close eye on SST to facilitate climate change adaptation.
