The paper discusses small-scale turbulence resulting from the breaking of internal gravity waves. The viewpoint that these waves can grow large enough to break is adopted, even in regions of large Richardson number, provided there is a source of wave disturbances either from mountains or hills or moving frontal surfaces in the atmosphere or eddies in the turbulent boundary layers of the atmosphere or oceans. In addition, there appears to be some process which tends to create thin layers in the atmosphere and oceans with large density and velocity differences across the layers. These regions tend to break down into strong turbulence from Kelvin-Helmholtz instability. A theory is discussed which relates to the occurrence of weak, sporadic turbulence in layers of large Richardson number in which the disturbances arise from eddies at the boundaries of these layers.
