英文摘要:

Typhoon-induced strong wind is a main factor leading local, weather-related sea-level rise with respect to the global climate change i.e. intensity and frequency of typhoon. This research mainly focuses on obtaining key relations of typhoon-induced wind and surges due to the increase of typhoon intensities. To obtain the winds and surges due to the climate change, this research has employed a dynamic surge model SLOSH (Sea, Lake, and Overland Surges from Hurricanes) which solves two-dimensional Navier-Stokes equations with wind obtained computation of pressure and wind direction for given stationary and circularly-symmetric storm as surface stress. Because of less expensive computational cost, it is suitable model for estimating typhoon-induced wind and surge heights with respect to the highly categorized hypothetical typhoons due to global warming. The hypothetical typhoons are composed by increasing mean sea level pressure (MSLP) and choosing corresponding radius of maximum wind (RMW) along a path of historical typhoon MAEMI (2003). The increment of MSLP resulted in the decrease of the maximum wind speed by same decline rations without dependence on the local characteristics. However, the typhoon-induced surge heights are strongly depending on the typhoon intensity and the local bathymetry. In addition, a comparison of numerically estimated wind to observational data resulted in +/- 50% error bounds which are corresponding to residuals appeared in the typhoon-induced surge heights.
