Abstract
Super Typhoon Haiyan (2013), which recorded a minimum central pressure of 895 hPa, struck the middle part of Philippines in November 2013, causing a huge storm surge disaster around the coast of Leyte Gulf. In this study, a high-resolution coupled typhoon-ocean model is developed to reproduce the Haiyan’s meteorological fields and storm surge from the genesis stage to the dissipating stage. It is indicated that the typhoon intensity of Haiyan and the resultant storm surge height around the coast of Leyte Gulf are acculately calculated by introducing movable nesting domains with a grid spacing of 3 km. We conclude that the distribution of ocean mixed layer depth over tropical cyclone basins is required to quantify the typhoon intensity and storm surge height with a high accuracy.
