Abstract
The destructive wind force from inland moving hurricanes may penetrate a considerable distance from the coast. The hurricane inland intensity decay and the translation speed are critical components for estimating the damage potential for inland regions. By employing the modified version of the decay period and the decay distance, this study investigates the relationship between hurricane inland decay and nearshore translation speed. We find that the variation between the decay period and decay distance can be well explained by the change of translation speed within 24 hours (h) before and after landfall. For cases that were still tropical storms within 24 h of landfall, the decay distance is found to be an exponential function of the translation speed during the first 24 h after landfall. The duration of inland destructive wind force as reflected by the decay period shows strong spatial variations along the U.S. coast. The outcome of this study may facilitate hurricane inland wind modeling as well as mitigation planning.
