摘要: Viscous dissipation is inadequate to account for the destruction of all thermal turbulence generated by upward transfer heat in a deep convection layer. It suggested that surplus turbulent kinetic energy destroyed buoyancy forces region downward upper part This process associated with mass downwards through (or subsidence) inversion and also an movement inversion, though latter may be overcome sufficiently strong subsidence. A simple theory developed results deduced thereby agree well observations diurnal variation height Central Australia.
