摘要

A spatial array of wave gauges installed on an observation platform has been designed and arranged to measure the local features of directional wave off Taishi coast of Taiwan. A new method, named the Bayesian Parameter Estimation Method (BPEM), was then developed and adopted to determine the main direction and the directional spreading parameter of directional spectra. Also, the Mitsuyasu's empirical formula of directional energy spreading was justified to be representative of wave field. It was shown that the bigger the waves age, the more rapid decrease in spreading. Nevertheless, the major portion of the wave energy, which is around the peak frequency, may not be completely related to the local wind condition. The relation between the parameter S(max) and the wave age, as suggested by Mitsuyasu's formula, may be improper in this area. The field data were shown that the wave steepness is more related to S(max) than wave age does. In general, the values of S(max) decrease as the values of the wave steepness increase.
