Abstract

Abstract

Using the SWAN model, the wave fields on the Taiwan Strait with two common wind field data including Cross-Calibrated Multi-Platform (CCMP) and ASCAT-Based Daily (DASCAT) are simulated and analyzed in this paper. A three-month period result during the northeast monsoon is compared with the buoy measured sequential wave height result. The mean of the deviations between them is less than 0.33 m and the root mean square (RMS) value of the deviations is no larger than 0.59 m. The deviations become larger when the buoy measured wave height is greater than 3.5 m or less than 1 m. And the simulation result of 6 h resolution wind field data agrees better with the buoy measured wave height than the 24 h resolution. Among the simulations with the input of the CCMP wind data with 6 h and 24 h resolution and the DASCAT wind data with 24 h resolution, the spatial cross correlation coefficient between either two results are no less than 0.90, the spatial mean of the deviations between either two results is less than 0.32 m and the RMS value of the deviations is less than 0.40 m.
