Characteristic and temporal variations of the wind wave fields over the adjacent waters of Taiwan Island based on T/P satellite altimeter data
The three probability density function distribution ( Rayleigh probability density function, Weibull probability density function, Log-Normal probability density function) of the SWH and wind speed, were combined with data from TOPEX satellite altimeter to conduct the comparison analysis of SWH and wind speed over the adjacent waters of Taiwan Island. The results showed that the Log-Normal probability density of the SWH is in good agreement with the histogram of the observed data in the whole scope, and the histogram of the measured wind speed is in good agreement with the Weibull probability density distribution. Most of the waters surrounding the Taiwan Island undergoes predominant annual changes. It was shown that the average of SWH was the largest in winter and reached the maximum in December. The maximum of mean SWH mainly occurred in summer and minimum in spring. The large waves normally appeared in winter and autumn. Meanwhile, Fourier expansion of the time series of SWH showed that wave energy corresponding with 1 -year cycle was the main component of wave height and wave energy on every pass.
