Abstract

The aim of this paper is to identify the magnitude of the wave climate change, investigate the trend as well as the rate of the change. Due to the lack of long-term wave observations around Taiwan, numerical simulations are carried out to obtain a near 30 years wave database for the statistical analysis. The results demonstrate strong inter-annual variations of the wave climate. The wave energy and wave slope decreased. Started from 2003 to 2006, significant trend of increase of wave energy (250%) and slope (30%) are identified. Wave propagation directions also features significant shift from Eastward propagation direction more to the north.

台湾波能变化之评估
本文的目的是确定波浪气候变化的幅度,研究波浪气候变化的趋势和速率。由于台湾地区缺乏长期的波浪观测资料,本文采用数值模拟的方法获得近30年的波浪数据库,以作统计分析之用。结果表明,波浪气候具有强烈的年际变化。波能和波斜率减小。从2003年到2006年,发现波浪能增加250%,坡度增加30%的显著趋势。波的传播方向也有明显的由东向北的转变。
