The evolution of long internal waves (IWs) with small amplitudes in a stably stratified fluid is governed approximately by a linear wave equation, with small but cumulative corrections due to weak nonlinearity, dispersion and dissipation, and possibly to a slowly varying background.
In [16], the author considers the three-dimensional reflection and diffraction properties of internal waves in the sea.
El Nino is covered along with the internal waves that propagate deep in the ocean, along the boundary between warm surface waters and cold deep water.
Washington, January 25 ( ANI ): Weather forecasters often make mistakes because the models they use for predicting weather can't accurately track highly influential elements called internal waves, researchers say.
The reason for such diversity lies in the mountain range itself, whose pinnacles interrupt the primary Gulf of Maine current and create a stunning oceanographic phenomenon known as internal waves, which carry high levels of nutrients and oxygen from the sea surface to the sea floor.
Internal waves play an integral role in oceanic and atmospheric dynamics by affecting global circulation patterns, maintaining environmental energy budgets, and acting as a source of turbulence and mixing.
His work includes research on turbulent processes, internal waves and tides, and boundary-layer processes.
1995) can drive the distribution of small aquatic organisms and disruption of normal vertical distribution of zooplankton has been attributed to down-welling and internal waves (Rinke et al.
As the spatial and temporal resolution of used sensors is often utilized to their limits, the general opinion of experts is that the used methods need further refinements, specifically to account for the complex dynamics associated with the presence of surface and internal waves [5].
But the lake bed itself is slowly being pried apart via the rift phenomenon, slowly eroding the lake's natural defence system -such as internal waves dissipating 'influxes of energy' - including that of moderate lava flows.
Long nonlinear internal waves, premelting dynamics, and large-eddy simulation of turbulent combustion are other areas explored.
