조석-해일 비선형성과 관련된 태풍-해일 특성

Abstract

Tide-surge interaction during typhoon periods has been analyzed. The quantitative analysis of the Chisquare test shows that the interaction is most prominent at the Southwestern coast whereas the Western and the Southeastern regions are not. Patterns of surge type were divided into two groups, that is, steep type and mild type. Then, the interaction was turned out to be more prominent for mild type data. The weak interaction at the Western region is considered due to negative surges when the south-track typhoons attack. However, the interaction is remarkable when the west-track typhoons attack. The weak interaction at the Southeastern coast is, on the other hand, considered due to abundance of the steep type typhoons. Thus, inundation risk would be so apprehensive at that region because large-scale surge might be caused even at high tide. 핵심용어: tide-surge interaction, typhoon, surge type, tide-modulated surge, typhoon track, 조석-해일 ë¹„ì„ í˜•ì„±, 태풍, 해일양상, 조석변조해일, 태풍경로
