Subject and Keywords:
The evolution of hydrodynamic instabilities in the convective flow of a fluid layer heated from below is considered, reviewing the results of recent theoretical investigations. Steady convection rolls and their instabilities, three-dimensional solutions in the form of knot convection, and traveling-wave convection are discussed, and results from numerical simulations are presented in graphs. It is shown that the instabilities of rolls offer a typical picture of several mechanisms involved in turbulent convection, and that turbulent convection, even at high Rayleigh and Reynolds numbers, still exhibits well defined structures and characteristic wavelengths. Such phenomena have been noted in satellite images of stratocumulus clouds or in observations of solar-surface granulation and supergranulation.
