  It is shown, using results of direct numerical simulations, laboratory
experiments, measurements in the atmospheric boundary layer, satellite infrared
radiances data, the planetary-scale surface-air and tropospheric data, that the
temperature fluctuations in atmospheric free convection can be well described
by the spatio-temporal distributed chaos approach based on the Bolgiano-Obukhov
phenomenology. A possibility of analogous consideration of the atmospheric
dynamics on other planets (Mars, Jupiter and Saturn) has been briefly discussed
using the data obtained with the Phoenix lander and the infrared observations.
