A review of tropical cyclone wind field models
J.A.B. Wills, B.E. Lee and T.A. Wyatt(U.K.)rn

    Engineered structures such as buildings and bridges in certain regions of the world need tornbe designed to withstand tropical cyclone winds, otherwise known as typhoons or hurricanes. In order torncarry out this design, it is necessary to be able to estimate the maximum wind speeds likely to bernencountered by the structure over its expected lifetime, say 100 years. Estimation of the maximum windrninvolves not only the overall strength of the tropical cyclone, but the variation of wind speed with radiusrnfrom the centre, circumferential position, and with height above the ground surface. In addition, not onlyrnthe mean wind speed, but also the gust factor must usually be estimated as well. This paper investigates arnnumber of recent mathematical models of tropical cyclone structure and comments on their suitability forrnthese purposes in a variety of scenarios.
