Abstract : A mathematical model is derived for the plane stationary problem of ordered thermal convection caused by the vertical instability of the atmosphere, with the assumption that there is no general air movement. The hydrodynamic patterns corresponding to the solution obtained are regarded as resembling a cumulus cloud. A specific example is calculated as an illustration of this conclusion. In the computed lines of flow, the cloud base lies at the level of condensation, the side boundary is drawn along the isoline w = 0.1 m/sec (where w is the vertical component of the wind velocity), the upper boundary corresponds to the isoline w = 0, the upper portion of the cloud resembles an anvil, and the anvil does not obtain when there is weaker inversion.
