A Study on the Wave Estimation of Typhoon MAYSAK-Based

In this study, re-analysis wind fields of KMA, JMA, and NOAA were collected for the estimation of waves during typhoon MAYSAK (2009). The wind field data of KMA, JMA, and NOAA were used as input conditions, and the significant wave height, peak period, and representative wave direction were estimated using SWAN (Simulating Waves Nearshore, version 41.31) numerical modeling. Calculation ranges of the typhoon wave estimation range from 20° to 50°N and 117° to 147°E, and the latitude and longitude were composed of grid size at 0.05° (about 5 km resolution). Experimental conditions were 0~360° 60 division for direction division, and 40 division for frequency division 0.04~1.0 Hz, and JONSWAP spectrum was used. In order to verify the reproducibility of the typhoon wave estimation results, quality-controlled wave observation data provided by WINK in the typhoon MAYSAK best track were collected, and the reproducibility of wave estimation data using KMA, JMA, and NOAA wind fields was compared and reviewed.
