Abstract
The time-dependent aerodynamic forces experienced by a structure immersed in the air flow relate to the wind properties directly. Understanding of the strong wind characteristics is very important for safe and serviceable design. This chapter focuses on strong winds and their characteristics. Wind climates that may bring strong wind, for instance monsoons, tropical cyclones, thunderstorms and so on, are briefly described together with the underlying hydrodynamics. Variation of wind speed with height above ground and turbulent structure inside the atmospheric boundary layer, including turbulence intensity and scale, gust factor, peak factor, decay factor of the coherence function, probability distribution function, power spectrum, and their variations with wind speed, are discussed in detail. In addition, Typhoon Maemi is referred as an example of strong wind event to exhibit the wind characteristics of strong winds.
