Analysis of Wave Characteristics over HsinChu Water

This paper adopts statistical methods to understand the wind and wave characteristics over the Hsinchu Water, where there are three observing pots: the coastal wind station, the Hsinchu data buoy station, the Kuokwang oil platform station. Based on the results of analysis, the following features over this water have been found. The wind fields over this water are dominated by monsoon. The wind speeds near coasts are less than those near offshore. However, the trends of observed wind speed among stations are similar. The differences of wind direction show that the deviations are smaller as the wind speed increased among three stations. The wave periods are normal distributions observed at buoy and platform stations, but the wave heights are not. There are, sometimes, two wave systems appeared in the join wave-period distribution. High correlations and lag time at +00-hr, or 2-hr are found between the wind and the wave observing item in each offshore station. The correlated formula for wave heights itself are power regression type for the summer, winter, and typhoon seasons. The typhoon cases are the highest correlation. Furthermore, the wave heights in Kuokwang oil platform area can be estimated from calculating the product of the Markov transfer matrix and wave height measured by the Hsinchu data buoy station. The error decreases when the wave heights increase, and it has the highest error in the summer season, smallest value in the typhoon duration. For the interesting high wave height, the error is less than 20%.short abstract (50 to 100 words) in a single paragraph should be included here.
