摘要

Typhoon waves play a major role in engineering and environmentalproblems. Our long-term goal is to investigate variability and trends oftyphoon waves over past 62 years. However, the parameters innumerical wave models need to be calibrated before a model can beapplied to a specific region. In this paper, we selected the 3 mostimportant parameters from the source term of the SWAN wave modeland subjected them to sensitivity analysis to determine which parameteris the most sensitive. After sensitivity analysis, we adopted the ARSmethod to find the optimal value of the parameter to which the SWANwave model is the most sensitive by comparing modeling results withobserved data at three buoys off the northeastern coastal waters ofTaiwan; the aim being to find optimal value of the parameter forimproved modeling of wave development. The procedure adopting theoptimal parameter in wave simulations did improve the accuracy of theSWAN wave model in comparison to default runs based on fieldobservations at three buoys.
