Abstract

This study is concerned with the estimation of fluctuation wind velocity spectrum and turbulence characteristics in the major cities reflecting the recent meteorological with typhoon wind velocity about 2003 (Maemi) 2010 (Kompasu) 2012 (Tembin). The purpose of this paper is to present spectral analysis for longitudinal component fluctuating velocity. In the processes of analysis, the longitudinal velocity spectrums are compared widely used spectrum models with horizontal wind velocity observations data obtained at Korea Meteorological Adminstration (KMA) and properties of the atmospheric air for typhoon fluctuating wind data are estimated to parameters with turbulency intensity, shear velocity and roughness length.

우리나라 전체 재해의 60%이상은 태풍과 같은 바람재난으로부터 발생하고 있으며, 이러한 자연 재해로부터 구조물이나 외장재의 안전과 사용성 측면에서의 내풍설계 과정에서는 풍속스펙트럼의 평가가 요구된다. 본 논문에서는 최근 우리나라를 통과한 태풍 2003년 매미, 2010년 곰파스, 2012년 템빈의 변동풍속자료로부터 난류의 특성을 알아보기 위하여 6개의 대표지점을 여수, 서울, 청주, 원주, 대구, 속초로 선정했다. 선정된 각 지점에 대한 태풍의 변동풍속자료는 기상청으로부터 획득했다. 기상청으로부터 획득한 변동풍속 자료는 연최대순간풍속과 연최대평균퐁속이 같은 날 발생했기 때문에 각 모집단의 표본 1440개 중 년최대순간풍속이 속하는 740개 풍속자료를 10분 평균풍속으로 가정하여 난류특성을 비교 검토하였다.
