Research and application of refined storm surge prediction system for Taizhou coastal based on ADCIRC model

To address practical needs in storm surge disaster prevention along Taizhou's coast, this study developed both an astronomical tide prediction model and a typhoon storm surge numerical refinement model. Building on these frameworks, we implemented a refined storm surge forecasting system for Taizhou's coastal areas using China's indigenous information technology architecture. Through operational forecasts of multiple typhoons, the system achieved an 80% average qualification rate with peak tide level predictions within ⪅±30cm, demonstrating excellent forecast accuracy and promising potential for practical application.
