Abstract : A system of equations of atmospheric hydrothermodynamics for the entire earth system is developed. The system is complicated by the consideration of radiative heat fluxes, and by phase transitions of atmospheric water which must be included both in the equation, and in the boundary conditions. To simplify the solution and to save computer time, the heat flux from atmospheric phase transitions is disregarded; the radiative heat flux over the entire volume of the atmosphere is preassigned. In this manner, the system of equations is reduced to nonlinear differential equations of hydrothermodynamics, and to a three-dimensional problem. The temperature is expressed through the geopotential, using the equation of statics written in an isobaric system of coordinates; the equation of atmospheric hydrothermodynamics is initially written in an isobaric-spherical system of coordinates. A given obtained solution is a system of n nonlinear algebraic equations with respect to unknown given coefficients; it can be used to develop a stationary picture of the circulation with a preassigned heat flux.
