Abstract

Using sea wave as an energy resource is growing in the world because of its cleanliness and recyclability. Wave energy depends on significant wave height and wave period. These parameters depend on the specification of some other parameters specially the wind filed. Blowing the wind over the sea water produces waves and makes them one of the best sources of energies. Hence wave climate depends to wind climate. Variation of the wind climate in the future climate, changes the hydrodynamic of waves including the wave power specification. The CNRM-CM6-SSP2-45 of CMIP6 is one of the middle classes carbon dioxide climate changes and has much application in managing and programing purposes. In this research the effect of this high-resolution climate scenario has been evaluated on the wave power in Chabahar in Sistan and Balouchestan province in the Gulf of Oman. For this, the improved Weibull downscaling technique has been used for downscaling of wind field. Using a calibrated wave model, it has been derived that in a period of ten years leading to 2100, the wave power will increase 0.22 kW/m (equal to 3%) in average. Seasonal variation is more sensible. Fall and Winter have most increasement in decrease. Average seasonal wave power will change in Fall and Winter by +2.27 kW/m (+42%) and -2.24 kW/m (-27%) respectively.
