Convection — This figure shows a calculation for thermal convection in the Earth s mantle. Colors closer to red are hot areas and colors closer to blue are cold areas. A hot, less dense lower boundary layer sends plumes of hot material upwards, and likewise,… … Wikipedia
Convection cell — Altocumulus cloud as seen from the space shuttle. Altocumulus is formed through convective activity. See also: Convection A convection cell is a phenomenon of fluid dynamics that occurs in situations where there are density differences within a… … Wikipedia
Convection zone — An illustration of the structure of the Sun: 1. Core 2. Radiative zone 3. Convective zone 4. Photosphere 5. Chromosphere 6. Corona 7. Sunspot 8. Granules 9. Prominence … Wikipedia
Instability strip — The Instability strip is a nearly vertical region in the Hertzsprung–Russell diagram which is occupied by pulsating variable stars (including RR Lyrae variable, Cepheid variable, W Virginis variable, ZZ Ceti variable, RV Tauri variable, Delta… … Wikipedia
Atmospheric convection — Conditions favorable for thunderstorm types and complexes Atmospheric convection is the result of a parcel environment instability, or temperature difference, layer in the atmosphere. Different lapse rates within dry and moist air lead to… … Wikipedia
Rayleigh–Bénard convection — Bénard cells. Rayleigh–Bénard convection is a type of natural convection, occurring in a plane of fluid heated from below, in which the fluid develops a regular pattern of convection cells known as Bénard cells. Rayleigh–Bénard convection is one… … Wikipedia
Convective instability — For a more general discussion of the same phenomenon, see Convective available potential energy. This article incorporates public domain text created by the US government. In meteorology, convective instability or stability of an airmass refers… … Wikipedia
Double diffusive convection — is an important fluid dynamics topic that describes a form of convection driven by two different density gradients which have different rates of diffusion.[1] Convection in fluids is driven by density variation within them. These density… … Wikipedia
Atmospheric instability — is a condition where the atmosphere is generally considered to be unstable and as a result the weather is subject to a high degree of variability through distance and time [ [http://www.ace.mmu.ac.uk/eae/Weather/Older/Stability of Air.html… … Wikipedia
Thermomagnetic convection — Ferrofluids can be used to transfer heat, since heat and mass transport in such magnetic fluids can be controlled using an external magnetic field. B. Finlayson first explained in 1970 (in his paper Convective instability of ferromagnetic fluids … Wikipedia
Convective available potential energy — A skew T plot showing a morning sounding with a large hydrolapse followed by an afternoon sounding showing the cooling which occurred in the mid levels resulting in an unstable atmosphere as surface parcels have now become negatively buoyant. The … Wikipedia
