| 英文摘要: | Quantitative assessments on the effect of translate speed of typhoons on wind waves were carried out.A WRF-SWAN coupled model that used observed meteorological data was applied to eight different typhoons in the vicinity of Shiono-Misaki, on the pacific side of Honshu Island, Japan. The authors proposed a new methodology to modify the translate speed and wind field of tropical cyclones using an empirical model in which the gross wind speed is expressed as the summation of two different types of wind generation. Two different trends of the relationship between the significant wave height (Hs) and translate speed (V) were found, describing the most dominant parameter. Typhoons with a modest intensity and size (for the case of Japan) generally showed a positive correlation between the change in the maximum Hs and V, which means translation wind speed was the dominant parameter. In contrast, stronger typhoons were less sensitive to the change in V and could maintain high waves even when almost stationary. With reference to the results, it is important to raise awareness of the future problems that could be caused by large storms that stall for prolonged periods of time. © 2020, Springer Nature B.V. |
