The horizontal boundaries of the convectioncell are a rhodiumplated copper mirror on the bottom and a sapphire window on the top. To model an unbounded system, we have therefore been led to conduct the present experiments in an annular convectioncell. It is possible to make a convectioncell with mean circumference of greater than 100 times the cell height. These density differences result in rising and/or falling currents, which are the key characteristics of a convectioncell.

One obvious method to suppress higher-dimensional behaviour in convection in rectangular containers is t o use narrow convection cells. The z-independent perturbation to the stream function is positive in the region near the wall where the convection cells are strongest. In this investigation an initial disturbance of the form of the counter-rotating convection cells predicted by linear theory was used. However, the linear results have counter-rotating convection cells, and experiments have only revealed cells that all rotate in the same direction. The instabilities that evolved consisted only of co-rotating convection cells. The heat is dissipated through large-scale convection cells. By its very nature the linear stability analysis predicts counter-rotating convection cells. At divergent plate margins, heat is dissipated through hydrothermal convection cells. This cooler fluid is then heated and the process continues, forming a convection current; this process transfers heat energy from the bottom of the convectioncell to top.

Volcanoes near plate boundaries and mid-ocean ridges are built by the decompression melting of mantle rock that rises on an upwelling portion of a convectioncell to the crustal surface.

Below this level previously established convection cells would decay. Mixing turned out to be very slow on the scale of the apparatus, since steady convection cells have closed streamlines : without some lateral dispersion it could have taken years ! The size of convection cells is largely determined by the fluid's properties. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In nature, convection cells formed from air raising above sunlight-warmed land or water are a major feature of all weather systems.

Accretion occurs over geoidal lows that can be caused by avalanche slabs or the downgoing limbs of convection cells.

The presence of alteration in all of the extrusive levels but the very highest imply a succession of numerous hydrothermal convection cells active during eruption. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Under experimental conditions, granular convection of variously sized particles has been observed forming convection cells similar to fluid motion. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The dayside of the planet has larger convection cells than the nightside. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It asserts that super plumes rise from the deeper mantle and are the drivers or substitutes of the major convection cells. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This down-welling of cooler liquid contributes to the driving force of the convection cells. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Some early models of plate tectonics envisioned the plates riding on top of convection cells like conveyor belts. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Buoyancy, and hence gravity, is responsible for the appearance of convection cells. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The zones are formed when rising convection cells form crystallizing ammonia that masks out these lower clouds from view. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Solar faculae are bright spots that form in the canyons between solar granules, short-lived convection cells several thousand kilometers across that constantly form and dissipate over timescales of several minutes. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The first relates to the evolution of a large population of convection cells which would be present, for example, in containers of large aspect ratio. Heat is dissipated effectively through the former by the formation of hydrothermal convection cells. These examples are from corpora and from sources on the web.
