Typhoon Storm Surge Simulation for Typhoon Haiyan <Research Note>
Kim Kyeong Ok
Abstract
Typhoon Haiyan (local name, Yolanda) in November 2013 brought record-breaking meteorological forcing, surface winds of 65 m/s and surface pressure of 895hPa at its maximum intensity, and made landfall over Samar Island, causing unprecedented disasters in the center of Philippines.
In this note, the numerical simulations for storm surge and wind waves, using unstructured mesh system are conducted. The atmospheric input is computed by Holland wind model. The radius of maximum wind is estimated by the other informations by JMA. The storm surge and wind waves are simulated with ADCIRC and SWAN. Large domain including the whole track of Typhoon Haiyan is constructed with triangular unstructured meshes, and results show the calculated storm surges of nearly 4 m in the San Pedro and San Pablo Bay.
