It is observed that the temperature distribution in 
the boundary layer changes qualitatively and the heat transfer in 
the upper part of a plate intensifies substantially in comparison 
with a surface with a continuous heat flux. For the case of substantial 
heat flux density in the initial stage of formation of a free convective 
flow a two-dimensional vortex is found to appear.
