동북아시아 해상에서의 태풍중심기압과 최대풍속의 경험적 관계식

Abstract

The empirical relationship between minimum central pressures and maximum wind speeds for Northeast Asian tropical cyclones was obtained by analyzing typhoon parameters and sea-surface winds observed at the East China Sea, the South Sea and the East (Japan) Sea of Korea for 20 years (1979 - 1999). The resulting empirical equation was compared with various relationships obtained from previous studies. The result shows a very close agreement with SPM's(1984) relation. However, it was much lower in wind intensity compared with other relations, and the differences in the maximum wind speed were increased as the minimum central pressures were decreased. The main cause of these discrepancies may lie in the quality of wind data obtained by either direct measurement or indirect estimation of sea-surface winds.
