  author={Elliott E. Schulman},
The instability of a flow modelling a linear oceanic thermocline is investigated with a view towards understanding the intermediate-scale fluctuations observed by Crease (1962) and others. Robinson's (1962) analysis of the stability of a thermal ocean circulation is extended to include amplifying quasi-geostrophic perturbations. North-south wavelengths of several hundred kilometers are predicted and agree with previous measurements. For the special case of perturbations independent of longitude… CONTINUE READING
