Turbulent wind characteristics of tropical cyclones based on a revised uniform analysis framework

Literature review exposes that field measured turbulent wind characteristics concerned by engineering applications, e.g., turbulence intensity, integral scale, gust factor and peak factor, are quite scattered in tropical cyclones (hurricanes and typhoon). In this study, the turbulent wind characteristics of seven tropical cyclones (four typhoons and three hurricanes) were comparatively investigated based on a revised uniform analysis framework to eliminate the potential observation-related effects. Specifically, field measurements of turbulent wind characteristics were converted to a standard reference station with a roughness length of 0.03-m, averaging time of 10-min for mean wind and duration time of 3-s for gusty wind at 10-m height. The obtained standardized turbulent wind characteristics in various typhoons and hurricanes were compared with the corresponding recommendations in ASCE7-10 and AIJ-RLB-2004. © 2017 Taylor & Francis Group, London.
