Wind shear — Wind shear, sometimes referred to as windshear or wind gradient, is a difference in wind speed and direction over a relatively short distance in the atmosphere. Wind shear can be broken down into vertical and horizontal components, with… … Wikipedia
Airy wave theory — In fluid dynamics, Airy wave theory (often referred to as linear wave theory) gives a linearised description of the propagation of gravity waves on the surface of a homogeneous fluid layer. The theory assumes that the fluid layer has a uniform… … Wikipedia
Lee wave — The wind flows towards a mountain and produces a first oscillation (A) followed by more waves. the following waves will have lower amplitude because of the natural damping. Lenticular clouds stuck on top of the flow (A) and (B) will appear… … Wikipedia
S-wave — can also refer to the lowest energy electronic wavefunction in atomic physics; see atomic orbital. A type of seismic wave, the S wave, secondary wave, or shear wave, sometimes called an elastic S wave, is one of the two main types of elastic body … Wikipedia
Seismic wave — Seismic waves are waves that travel through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion. Seismic waves are also continually excited by the pounding of ocean waves and the wind. Seismic waves are… … Wikipedia
Love wave — In elastodynamics, Love waves are essentially horizontally polarized shear waves (SH waves) guided by an elastic layer, which is welded to an elastic half space on one side while bordering a vacuum on the other side. In seismology, Love waves… … Wikipedia
Gravity wave — In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two media (e.g. the atmosphere or ocean) which has the restoring force of gravity or buoyancy.When a fluid parcel is displaced on an interface or… … Wikipedia
Lamb waves — propagate in solid plates. They are elastic waves whose particle motion lies in the plane defined by the plate normal and the direction of wave propagation. In 1917, the English mathematician Horace Lamb published his classic analysis and… … Wikipedia
горизонтально поляризованная поперечная волна — SH волна Поперечная волна, в которой частицы среды колеблются перпендикулярно плоскости падения. [Система неразрушающего контроля.

Quartz crystal microbalance — A quartz crystal microbalance (QCM) measures a mass per unit area by measuring the change in frequency of a quartz crystal resonator. The resonance is disturbed by the addition or removal of a small mass due to oxide growth/decay or film… … Wikipedia
Electro Magnetic Acoustic Transducer — An Electro Magnetic Acoustic Transducer (EMAT), is a non contact inspection device that generates an ultrasonic pulse in the part or sample inspected, instead of the transducer. The waves reflected by the sample induce a varying electric current… … Wikipedia
