Investigation of Tropical Cyclone Wind Models With Application to Storm Tide Simulations

The hazards induced by tropical cyclones (TCs), for example, high winds, extreme precipitation, and storm tides, are closely related to the TC surface wind field. Parametric models distribution have been widely used risk analysis due their simplicity efficiency in application. Here we revisit parametric modeling of fields, including symmetrical asymmetrical components, its applications tide North Atlantic. field has motion vertical shear; however, find that a simple empirical background-wind model, based solely on rotation scaling vector, can largely capture observed asymmetry. implicit inclusion shear effect be understood with climatological relationship between general directions during hurricane seasons. For symmetric field, Holland profile is chosen as benchmark physics-based complete model connecting inner core outer region performs superiorly compared data set. When forcing simulations, integrated asymmetry reproduce tides lower errors than often-used coupled translation-speed-based method.
