Ocean wave height is one of the critical factors to decide efficiency ocean energy conversion system. Usually, only when resonate occurs between (ocean speed in vertical direction) and system, can from into electric be maximized. Therefore, this paper proposes two predication methods predict future 1.5–2.5 s. Firstly, data fitting real achieved by polynomial method, which beneficial height. Sec...

Underwater gliders are a class of AUVs designed for high endurance over long distances, but their reduced velocity makes them more susceptible to ocean currents during deployment. Thus, feasible paths need to be generated through the ocean current field. This paper proposes a method for determining energy-optimal paths that account for the influence of ocean currents. The proposed technique is ...

In this work we study analytically and numerically the performance of the mean heave motion of an OWC coupled with the governing equation of the spreading ocean waves due to the wide variation in an open parabolic channel with constant depth. This paper considers that the ocean wave propagation is under the assumption of a shallow flow condition. In order to verify the effect of the waves in th...

It is well known that the intertropical convergence zone (ITCZ) shifts in response to remote perturbations in the atmospheric energy balance, with shifts roughly in proportion to changes in the cross-equatorial atmospheric energy flux. However, atmospheric and oceanic energy fluxes in low latitudes are mechanically coupled, and the oceanic energy flux dominates the atmospheric energy flux. Here...

Quadratic bottom boundary layer drag is a potentially significant source of energy dissipation in the deep ocean. This study presents a new estimate of the energy dissipated by this process, using results from the world’s largest archive of ocean current meter time series and focusing strongly upon the potential uncertainties in this calculation. Two methods are used, one based on a simple divi...

Progress in ocean wave forecasting is described in the context of the fundamental law for wave prediction: the energy balance equation. The energy balance equation gives the rate of change of the sea state caused by adiabatic processes such as advection, and by the physical source functions of the generation of ocean waves by wind, the dissipation due to whitecapping and the nonlinear four-wave...

Linear and nonlinear radiating instabilities of an eastern boundary current are studied using a barotropic quasigeostrophic model in an idealized meridional channel. The eastern boundary current is meridionally uniform and produces unstable modes in which long waves are most able to radiate. These long radiating modes are easily suppressed by friction because of their small growth rates. Howeve...

continuous and lengthy droughts in previous years not only in the southern provinces of iran but also in the whole country necessitate optimized water management. indian ocean and adjacent seas in south of iran are suppliers of part of the humidity in the region and the variation on indian ocean sea surface temperature has an important role in evaporation from oceans and input humidity into atm...
