three-dimensional wave-breaking onset does not limit how steep waves may become, and we produce directionally spread waves 80% steeper than at breaking onset and four times steeper than equivalent two-dimensional waves at their breaking onset. Our observations...
Particle image velocimetry has been used to examine three-dimensional breaking wave kinematics. Two cases of wave breaking were studied. In the first case, the wave field contains a single frequency with a uniform angular spreading within a given range {{ —α, α.}}. The wave field of the...
We consider the three-dimensional dynamics of a breaking Rossby wave on the edge of a cylindrical, axisymmetric vortex, as a representation of breaking planetary waves on the winter stratospheric polar vortex. A complete understanding of the mechanisms involved is not only important for, e.g., ...
Only models that can realistically represent the bathymetry at sufficient resolution, include spatial variations in stratification, and take into account not only wind speed but also wind direction can accurately represent the three dimensional movement of water, internal wave dynamics, upwelling and ...
Computer holography is a prominent technique for reconstructing customized three-dimensional (3D) diffraction fields. However, the quality of optical reconstruction remains a fundamental challenge in 3D computer holography, especially for the 3D diffraction fields with physically continuous and extensive depth...
Three-dimensional structured illumination microscopy (3D-SIM) doubles the spatial resolution along all dimensions and is used widely in cellular imaging. However, its temporal resolution is constrained by the need for sequential plane-by-plane movement of the sample using a piezo stage for imaging, ...
Non-Linear Three-Dimensional Effects On Gravity-Wave Drag: Splitting Flow and Breaking Waves 来自 Wiley 喜欢 0 阅读量: 49 作者: P.,M.,A.,Miranda,I.,N.,James 摘要: A study has been made of some aspects of frictionless stratified flow past three-dimensional isolated mountains. the study ...
The high-level GN (GN-3 and GN-4) models are applied to three-dimensional wave problems for the first time. Three test cases are considered here. First one is on the wave evolution in a closed basin. The symmetry, in the x and y directions in this case, verifies that the algorithm ...
Three-dimensional steady capillary-gravity water-waves are studied in this paper. Potential flow of an ideal fluid in a layer with finite depth and upper free surface is considered. The existence of these waves is derived through bifurcation processes from the state of rest. The waves are assume...
Wave-induced currents play a critical role in coastal dynamics, influencing sediment transport and shaping bottom topography. Traditionally, long- and cross-shore currents in coastal zones were analyzed independently, often with two-dimensional models for longshore currents and undertow being used. The ...
