Convection cells can form in any fluid, including the Earth's atmosphere, boiling water or soup (where the cells can be identified by particles they transport, such as grains of rice), the ocean, the surface of the sun, or even a farmer's field, ...
convection cell"1. An organized unit of convection within a convecting layer. It is isolated by a stream surface, with ascending motion in the center and descending motion near the periphery, or vice versa.
Convection Cell - Circulation that results from the uneven heating of a fluid; the warmer parts of the fluid expand and rise because of their buoyancy and the cooler parts sink.
Convective condensation level (CCL) The altitude at which air parcels rising with the updraft of a convection cell reaches saturation; coincides with the base of cumuliform clouds.
larger scale, and are driven by a combination of gravitational and centrifugal forces acting at an angle to the vertical.) Almost all atmospheric and oceanic convection is fully turbulent and is generally composed of a collection of convection cells, ...
