ABSTRACT
In the previous chapter we came across the fact that the behaviour of the thermal boundary layer in connection with the origin of primary convective motions in it could be represented as a cyclical one-dimensional process. It turned out later that the one-dimensional idea of cyclical growth (up to critical instability) and destruction of the thermal boundary layer agreed very well with the fact of three-dimensionality of the space structure of the primary convective motions near the water surface detected by more accurate observations. It became clear that the thermal boundary layer in reality had a three-dimensional structure whose space-time variability during observation on an isolated vertical only created the impression of a quasi-periodic (cyclical) process.
