The breaking process of the K-H wave in an unsteady exchange flow is investi-gated through the experiment by using a simple visualization technique. Two-dimensional vortex pairing, convective rolles and knots which are mentioned by S.A. Thorpe as transitional phenomena of turbulence in stratified fluids are con-firmed in the flow of the low Richardson number. On the other hand, the flow condition of the high Richardson number brings several uninvestigated three-dimensional breaking process.
