  2. Kelvin–Helmholtz instability - Wikipedia

    en.wikipedia.org/wiki/KelvinHelmholtz_instability

    Kelvin-Helmholtz instabilities are visible in the atmospheres of planets and moons, such as in cloud formations on Earth or the Red Spot on Jupiter, and the atmospheres of the Sun and other stars. [1] Spatially developing 2D Kelvin-Helmholtz instability at low Reynolds number. Small perturbations, imposed at the inlet on the tangential velocity ...

    The Met Office said: "Kelvin Helmholtz clouds, or fluctus clouds, are quite rare. "These clouds are more likely to be seen on windy days when there is a difference in density of the air.

  4. Kelvin–Helmholtz mechanism - Wikipedia

    en.wikipedia.org/wiki/KelvinHelmholtz_mechanism

    The KelvinHelmholtz mechanism is an astronomical process that occurs when the surface of a star or a planet cools. The cooling causes the internal pressure to drop, and the star or planet shrinks as a result. This compression, in turn, heats the core of the star/planet.

    A curious cloud seen over Smith Mountain looks more like something out of a fairytale than it does real life — and the science behind it is fascinating. What are Kelvin-Helmholtz clouds?

    KelvinHelmholtz cloud Fluctus clouds over Mount Duval in Australia Crested wave-like clouds formed by wind-shear instability that may occur at any altitude in the troposphere. Accepted as a WMO supplementary feature with the Latin name fluctus .

  7. Hydrodynamic stability - Wikipedia

    en.wikipedia.org/wiki/Hydrodynamic_stability

    This is an image, captured in San Francisco, which shows the "ocean wave" like pattern associated with the KelvinHelmholtz instability forming in clouds. The KelvinHelmholtz instability (KHI) is an application of hydrodynamic stability that can be seen in nature. It occurs when there are two fluids flowing at different velocities.

  8. Mammatus cloud - Wikipedia

    en.wikipedia.org/wiki/Mammatus_cloud

    KelvinHelmholtz (K–H) instability is prevalent along cloud boundaries and results in the formation of wave-like protrusions (called Kelvin-Helmholtz billows) from a cloud boundary. Mammatus are not in the form of K-H billows, thus, it is proposed that the instability can trigger the formation of the protrusions, but that another process ...

  9. Stable and unstable stratification - Wikipedia

    en.wikipedia.org/wiki/Stable_and_unstable...

    Depending on the size of the velocity difference and the size of the density contrast between the layers, Kelvin-Helmholtz waves can look different. For instance, between two layers of air or two layers of water, the density difference is much smaller and the layers are miscible; see black-and-white model video.
