Under the light of recent developments of the theory of matter-radiation interaction in the presence of magnetic field applied to non-LTE spectropolarimetry in astrophysics, we have revisited the theory of anisotropic resonance line scattering in moving media by means of the density-matrix formulation. This has led us to present a theoretical method of determination of the matter velocity field...

To what extent is tropical variability forced from the North Pacific through ocean pathways relative to locally generated variability and variability forced through the atmosphere? To address this question, in this study we use an anomaly-coupled model, consisting of a global, atmospheric general circulation model and a 41⁄2layer, reduced-gravity, Pacific-Ocean model. Three solutions are obtain...

Wind effects on the evolution of a breaking wave group due to dispersive focusing are investigated using two-phase flow Navier–Stokes solver. The equations solved for both air and water, with air–water interface captured by Volume Fluid method turbulence Smagorinsky subgrid-scale stress model. model is first validated experimental measurements without following wind action. delays shifts locati...

The mitigation of potential climate change while sustaining energy resources requires global attention and cooperation. Among the numerous strategies to reduce Green House Gas (GHG) emissions is to decommission carbon intensive electricity production while increase the deployment of renewable energy technologies – such as wind and solar power generation. Yet the generation capacity, availabilit...

The worldwide demand for energy is steadily growing. Environmental pressure has driven the power generation shift from fossil fuel to more 'green' sources of supply, such as wind or solar. However, the intermittent nature of wind has also brought many uncertainties to network operation. Traditionally, to have a sufficiently secure operational margin, a transfer limit is calculated based on iter...

in order to recognize the wind erosion situation of a region, the survey of its windiness is not sufficient and the physical characteristics of earth are of importance too. in fact, the outbreak of dust storms in a region is due to the sensitivity of earth and domination of wind in that region. in this investigation we have tried to find a way for determining the regions in which a dust storm i...

introduction: in modern societies, shift work is an essential component of daily life. since the beginning of research in shift work, researchers have been engaged in the identification of factors predicting adjustment and adaptation to shift work. the concept of adaptation and tolerance refers mainly to the biological response in terms of circadian rhythms and performance efficiency as well as...

Nowadays, propagation of wind turbines make challenges to supply safe power to the grid. Because of wind speed changes, supervisors are concerned to wind turbines, be able to produce appropriate electric power during the wind speed changes. As a matter of fact, investors are mostly like to invest on offshore wind farms, because of their more stable and continuous wind speed rather than onshore ...

Interannual variability of the Atlantic inflow (AI) into Nordic Seas is studied using moored current and temperature measurements in Norwegian Current during 25-year period 1995–2020. We show that properties AI are strongly connected to dynamics Northern demonstrate robustness average winter wind field driving with 3-month maxima range (40–50) cms−1. In sense, zero-wind-stress-curl (ZWSC)-lines...
