Abstract

It is shown that the atmospheric thermal (buoyancy driven) convection plays the main role in generation of the strong chaotic fluctuations of the global temperature through the Kolmogorov-Bolgiano-Obukhov mechanism (in the frames of the distributed chaos approach). It is valid for the planets with substantial atmosphere such as the Earth and Mars. Direct numerical simulations, the Berkeley Earth daily surface-atmospheric temperature dataset (over land) as well as the MACDA Mars reanalysis of the data inferred from the Thermal Emission Spectrometer measurements for the Mars Global Surveyor satellite were used in order to support this conclusion.
