dc.description.abstract2003년 남해안에 내습한 태풍 매미에 의해 발생한 폭풍해일과 파랑을 JMA-MSM 예보기상자료, NCEPCFSR 재분석 기상자료, ECMWF-ERA5 재분석 기상자료, JTWC의 최적경로를 이용한 기상자료를 이용하여 수치모의하고, 계산된 해일고를 전국 해안의 항만에서 관측된 폭풍해일 시계열 자료와 비교하였다. 폭풍해일과 동시에 발생하는 파랑에 대해서는 계산된 유의파고를 관측 자료와 비교하였다. 이 비교를 통해 태풍 매미에 대한 각종 기상장의 신뢰도를 평가하였다. 그 결과 JMA-MSM 기상자료가 가장 신뢰도가 높았고, JTWC의 최적경로를 이용한 기상자료도 상당히 우수하게 나타났다. ECMWF-ERA5 기상자료는 전반적으로 해일고나 파고의 크기가 작게 나타났으며, NCEP-CFSR 기상자료는 태풍 매미의 특정 경우에 대해 신뢰도가 가장 낮게 나타났다. 이 연구를 통하여 폭풍해일과 파랑을 추산하기 위해 신뢰도 높은 기상장이 필수적임을 알 수 있었다.-
dc.description.abstractNumerical simulations of the storm surge and waves induced by the Typhoon Maemi incident on the south sea of Korea in 2003 are performed using the JMA-MSM forecast weather field, NCEP-CFSR reanalysis weather field, ECMWF-ERA5 reanalysis weather field, and the pressure and wind fields obtained using the best track information provided by JTWC. The calculated surge heights are compared with the time history observed at harbours along the coasts of Korea. For the waves occurring coincidentally with the storm surges the calculated significant wave heights are compared with the measured data. Based on the comparison of surge and wave heights the assessment of the reliability of various weather fields is performed. As a result the JMA-MSM weather fields gives the highest reliability, and the weather field obtained using JTWC best track information gives also relatively good agreement. The ECMWF-ERA5 gives in general surge and wave heights weaker than the measured. The reliability of NCEP-CFSR turns out to be the worst for this special case of Typhoon Maemi. Based on the results of this study it is found that the reliable weather fields are essential for the accurate simulation of storm surges and waves.-
