In this study the interaction with a free surface of an initially aximmetric het issuing beneath and parallel to the surface was examined to determine the origin of the "surface current" - the large outward velocity which exists in a thin layer adjacent to the surface. Using the equations of mean motions, it is shown that near the surface, outward acceleration results from the balance between a positive contribution from the lateral Reynolds-stress gradients and a negative contribution from the lateral pressuregradient. In this study this phenomens are investigated and discussed in detail and compared with experimental results of investigation
