碩士 / 國立臺灣師範大學 / 地球科學系 / 107 / Typhoon Haiyan (2013) is a record-breaking typhoon that caused thousands of fatalities and large damages in the Philippines in November 2013. This study uses COAWST (Coupled Ocean Atmosphere Wave Sediment Transport Modeling) to simulate the typhoon Haiyan and explore the influences of different conditions on typhoon track and intensity. The results show that the coupling conditions of different complexity or the ocean background conditions of different years (2008-2013) have little effect on the typhoon track, but it will have a great impact on the intensity. The results show that the typhoon intensity simulated by the two-way coupling condition relative to other coupling conditions is more consistent with the observed data. In addition, the oceanic background environment in different years has a great impact on the typhoon intensity. Although the experiments are slightly different, the ocean environment in 2010 is more conducive to typhoon development. This result shows that under the same atmospheric conditions, Haiyan will probably be stronger in 2010 than the actual Haiyan in 2013, which means that even if Haiyan is already a very strong super strong station, it will be greatly enhanced. This study show that the NECC (North Equatorial Counter Current) transports heat into the development region of the Haiyan typhoon when the current northward shifts. The additional heat source provided by this horizontal advection that favors the development of the Haiyan typhoon.
