Solar radiation and atmospheric dynamics

Abstract

This paper studies the problems of mathematical description of physical processes in open non-equilibrium atmosphere. It is proposed that the mathematical description should be based on the idea that properties of an open system are determined by the properties of its elements and external constraints. It is also explained why atmosphere should be represented by an open non-equilibrium system of gas and radiation. Difference between physical processes in the above mentioned system and equilibrium atmosphere is given. The modification of equations of non-equilibrium thermodynamics for a system of gas and radiation is proposed. Possible ways for further development of tools of non-equilibrium thermodynamics are considered.

The analysis of daily dynamics of geomagnetic field variations spectrum under quiet and disturbed conditions

“…Atmospheric energy and the exchange of entropy between the atmosphere and the space has been understood in a number of works from the perspective of nonequilibrium thermodynamics. To describe dynamic processes in the atmosphere, the atmosphere has been modelled as a two-component medium consisting of gas and radiation -that comes from the Sun and from the Earth's surface -that interacts with it (Essex, 1984;Somsikov, 2014;Kshevetskii et al 2021). Andreev et al (2018) present the results of calculations of the dispersion relation obtained for linearized system of gas-radiation equations.…”
