Description
Summary:The thermohydrodynamic equations that describe convection in a compressible or incompressible fluid, thermochemical convection, and convection in the presence of thermal diffusion are formulated. The mechanisms for the origin of the global atmospheric and oceanic circulation are reviewed. Interlatitudinal convection and jet streams are discussed, as well as monsoon circulation and the mean meridional circulation of ocean waters due to the temperature and salinity gradients. Also described are the hypotheses for convective motion in the mantle and the thermal-wave (moving flame) mechanism for inducing global circulation (the atmospheres of Venus and Mars provide illustrations). Also considered are medium- and small-scale convective processes, including hurricane systems with phase transitions, cellular cloud structure, and convection penetration into the ocean, with its stepped vertical temperature and salinity microstructure.
