In systems consisting of two immiscible liquids in the gravity force field, convective instability may set in not only on heating from below, but also on horizontal-homogeneous heating from above, i.e., on stable density stratification of each of the media. In a number of previous works, a linear theory of this type of instability ("anticonvections") has been developed. In the present work, analytical estimates of the characteristics of finite-amplitude anticonvection have been made for the first time for the limiting case of neutral stratification of one of the media.
