Regional Wave Climate Projection Based on Super-High-Resolution MRI-AGCM3.2S, Indian Ocean

抄録

 High quality wave data in data-scarce regions are required in order to provide a reliable source for wave climate assessment. In this study, numerical modeling was utilized in order to generate the wave characteristics in the Indian Ocean (IO) region using super-high-resolution wind field MRI-AGCM3.2S as forcing. The model was evaluated in comparison to the satellite data and the validated model was performed to simulate historical and future projections of the wave in the study area (25 years for each period). Comparison of mean annuals of the wave indicated a slight decrease of significant wave height (SWH) in the Northern Indian Ocean (NIO) and middle parts of the Southern Indian Ocean (SIO) while there is a considerable increase near the southern ocean adjacent to Antarctica. The change of mean wave period (T_m01) will be less in the future, however, there will be a considerable increase in the south of India. The results of this study indicate the different patterns of change for wind and wave parameters in different regions of the IO.
