To the memory of Professor Lev Grigor’evich Kachurin
Abstract
Analysis of the existing theories of hailstone growth has shown that there are two different approaches to the explanation of the layered structure of hailstones. L.G. Kachurin showed that the layered structure of ice on the surface of an object placed into the flux of supercooled water aerosol is controlled by the equilibrium film thickness. Another approach is based on the equation of heat balance at the hailstone surface and on the introduction of the critical water content. This paper elucidates the meaning of the critical equilibrium film thickness and establishes the relation between the two existing criteria controlling the transition from the dry regime of hailstone growth to the wet regime.
