Impacts of climate change on wave regimes in the East Sea

Abstract

The study applied the PRECIS and SWAN modelling packages to simulate wind and wave regimes under climate change in the Vietnam East Sea. The results indicated that under RCP4.5 climate change scenario, by the end of the century, there are significant changes in both wave height and wave period in summer and winter months. In the East Sea during July, wave height is expected to increase 11.5% while wave period expected to increases 3.3%. On the other hand, wave height in January is projected to decrease approximately 7% while wave period in the same month is projected to decreases 4.4%. There are no significant changes in wave direction.
