Study On Time And Spatial Distribution Of Wind And Wave Energy Resources In The North Indian Ocean

In recent years,the world economy has been developing rapidly.The proposal of the Belt and Road has accelerated the economic exchanges and technical cooperation between China and other countries.Meanwhile,the demand of each country for energy is increasing day by day.The northern Indian Ocean area is located near the center of Maritime Silk Route.With its superior geographical location and abundant energy resources on the sea,it can meet the energy needs of passing ships and neighboring countries,and promote economic development and environmental improvement.Firstly,ERA-interim wind field data was used to simulate and calculate the wind energy resources in the northern Indian Ocean,including the annual average wind speed,exploitable wind energy,wind energy and stability,etc.It was found that the sea areas rich in wind energy resources were mainly distributed in Somalia,the Arabian sea,Sri Lanka,the Bay of Bengal and the northeast waters of Madagascar.Wind energy resources are rich and stability is good.The abundant and stable wind energy resources in these sea areas are suitable for the development and utilization of wind energy resources.Secondly,the theory of WAVEWATCH-? wave numerical model,range selection and mode setting of one-way nest mode are introduced,and two simulation methods are used to calculate the significant wave height of the northern Indian Ocean.The simulation results are verified and compared with the satellite altimeter data,and it is found that the significant wave height simulated by one-way nest mode is closer to the satellite data.Finally,the one-way nest mode is used for the first time to calculate the distribution characteristics of wave energy resources in the North Indian Ocean,including annual average significant wave height,exploitable wave height,annual average and seasonal average wave energy density,wave energy stability and wave effective storage.It is found that the contours of the waters near the Bay of Bengal and Sri Lanka protrude to the north,which is obviously affected by the swells of the South Indian Ocean.By using the wave data simulated by the one-way nest mode in the North Indian Ocean,more accurate distribution characteristics of the wave energy resources in the North Indian Ocean are obtained,which helps to better develop and use the wave energy resources in the North Indian Ocean.
