Project Details

Description

The aim of this research was to investigate the sustainability of wave energy resources in an appropriate location with high potential of wave energy harvesting considering the climate change impacts. Indian Ocean was selected as the target area due to the lack of any comprehensive study in that area on climate change impact on wave characteristics and wave energy. The wind data to force the wave model was obtained from a super-high-resolution product of the Japan Meteorological Agency (JMA) (MRI-AGCM3.2S) with horizontal spatial and temporal output resolutions of 20 km and 1 hr., respectively. The wave modeling was performed for both historical (1979-2003) and future (2075-2099) projections. Based on the fifth phase of the Coupled Model Inter-comparison Project (CMIP5), the scenario of future climate was considered by Representative Concentration Pathway (RCP) 8.5 as defined by -representing trajectories of increasing global radiative forcing reaching +8.5 W m-2, by the year 2100 compared to pre-industrial conditions. SWAN numerical model was used to simulate the wave characteristics in the study area. Satellite multi-mission wave measurements available from 2010 to 2018 covering the whole domain with spatial and temporal resolutions of 1° and daily, respectively, were used for validation of the wave model. After the model validation, it was used to generate the wave characteristics in domain for historical and future projections and the produced time series were used for climate analysis. The discussion was carried out in different time scales to consider oceanic phenomena such as monsoons and tropical cyclones. In addition, the short-term variations in annual, seasonal and monthly scales and long-term changes due to climate change and their combination were investigated focusing on the nearshore areas around the Indian Ocean basin to represent a novel concept for the stability of the wind and wave parameters.
