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.
