조석-해일-해파 결합 모형을 이용한 태풍 볼라벤 시뮬레이션

Abstract

The recent introduction of unstructured wave models has made nesting unnecessary and the coupled system can run on the same unstructured mesh. This identical and homogeneous mesh allows the physics of wave-circulation interactions to be correctly resolved in both models. The unstructured mesh can be applied to a large domain allowing all energy from deep to shallow waters to be seamlessly followed. There is no nesting or overlapping of structured wave meshes, and no interpolation is required. The waves and storm surge were allowed to develop on the continental shelf and interact with the complex nearshore environment. The integrally coupled wave-tide-surge modes are developed based on the hydrodynamic and spectral wave models, ADCIRC-SWAN and SELFE-WWMII. This study simulates the typhoon Bolaven which hit the Korean Peninsula in 2012 and cause the serious damage of 19 victims using two modeling systems. The model results are compared with the observations and the model performance is evaluated. The resulting modeling system can be used extensively for prediction of the typhoon surge and usual barotropic forecast. The result show that it is important to incorporate the wave-current interaction effect into coastal area in the wave-tide-surge coupled model. At the same time, it should consider effects of depth-induced wave breaking, wind field, currents and sea surface elevation in prediction of waves. Especially, we forectly resolved in both models.
