한반도 태풍내습 시 태풍경로별 나타나는 최대풍속 분포특성 연구

Abstract

In this study, the typhoon disaster prevention model was used to estimate the maximum wind speeds during the track of typhoons that affected the Korean peninsula from 2002 to 2015. RSMC Tokyo Typhoon Center’s best track data and the WRF numerical modeling results using the RDAPS data from the KMA were used as input data. The frequency of the influence according to the track type of all typhoons that affected the Korean peninsula during the study period (2002~2015) was analyzed. As a result, Type 7, which affects the Korean peninsula after passing Japan, was the most common, followed by Type 2, which landed directly on the Korean peninsula having arrived through the South Sea of Korea. The monthly track type of typhoons that affected the Korean peninsula were also analyzed. In September, Type 2 and Type 7 typhoons were observed frequently. The highest frequency of the maximum wind speed of 3-Second gust that can occur during a typhoon attack was observed for Type 2, The distribution of Type 2 showed a high frequency of 3-Second gust throughout the Korean peninsula, including the South and East Sea of Korea. In the case of the Type 2 track, which has a direct impact on the Korean peninsula due to typhoons landing from the South Sea, the frequency of occurrence was the second highest throughout the study period, and the 3-Second gust value, which is the maximum wind speed that could occur during a typhoon attack, was the highest. If this information is used as basic data in the typhoon disaster prevention system, it will contribute to future typhoon disaster prevention.
