N2 - It has been found experimentally that a row of two-dimensional vortices forms in an offshore zone when surface waves climb up a sloping flat bed. The vortices occur near the separation point of the Stokes layer, i. e. , near the breaking point, and are transported in the offshore direction. Performing the vortex pairing, the vortices increase their length scales offshorewards. They are nearly equal to the local depth of water. In the case when the slope of the bed from the horizontal is 2. 44+20,the row of vortices appears when h//b/L//b APP 1STH 0. 096. Here, h//b and L//b are the mean water depth and the wavelength at the breaking point, respectively.
