ON CONVECTIVE INSTABILITY OF AIR IN THE SNOW COVER
M. K. Zhekamukhov and I. M. Zhekamukhova UDC 532.5 This paper considers the system of equations describing the convective instability of air in the snow cover. We analyze the conditions under which the principle of "monotony" of normal perturbations is fulfilled and estimate the critical parameters of the main level of air equilibrium instability with allowance for the heat and mass exchange between the snow surface and the environment.
