Sentences with phrase «wave phase speeds»

No significant decrease in planetary - scale wave phase speeds are found except in October - November - December, but this trend is sensitive to the analysis parameters.

Not exact matches

Standing air pressure waves at the mouth of each runner were essentially in phase, while prior manifolds had waves out of phase at low speed, resulting in rumbling noises.

For higher stability, there's a stronger restoring force on any vertical displacement of air (assuming no latent heating occurs), which speeds up the motion associated with the wave causing the wave to propagate faster (i.e. faster phase speed).

Similarly, when the stability is lower, the wave motions will be deeper, and the phase speed should slow down.

Any physical wave should manifest a characteristic phase speed and direction.

Space - time spectral analysis is used to obtain the variance and phase speed of dominant convectively coupled equatorial waves, including the MJO, Kelvin, equatorial Rossby (ER), mixed Rossby - gravity (MRG), and eastward inertio - gravity (EIG) and westward inertio - gravity (WIG) waves.

However, the variances are generally too weak for all wave modes except the EIG wave, and the phase speeds are generally too fast, being scaled to excessively deep equivalent depths.

Free extratropical Rossby waves with zonal wave numbers about 6 to 8 mostly occur as high - amplitude, fast traveling waves (the so - called synoptic transients responsible for much of the weather variability in the extratropics); once established, they can freely propagate predominantly to the east with a phase speed c ≈ 6 − 12 m ⋅ s − 1 without maintenance from external forcing.

The simulations indicate that these nonlinear lee waves propagate against the generating flow (usually the tide) and are arrested because they have the same phase speed as the oncoming flow.
