Characteristics of Sea Current under Typhoons due to Long-term Fixed Observations in Amitori Bay, Iriomote Island

A study conducted in Amitori Bay, Iriomote Island, reveals that the traditional bulk formula for estimating sea surface resistance coefficients, derived from past typhoon wind speeds, may not accurately predict coastal flooding under the intensified typhoons expected with climate change scenario A1B. This finding underscores the urgent need for more observational data on future typhoons to improve the accuracy of storm surge prediction models. The research utilized long-term fixed observations to analyze sea current characteristics during typhoons, highlighting a critical gap in current predictive modeling that could significantly impact coastal management strategies.
