The “lows” move up the coast from the south at intervals of a few days, and bring in their wake south-westerly winds; when these are of gale intensity, they are termed “busters”.
It is of course possible that standing eddies may be generated by the sudden change in the 200 m isobath north of Durban – there is evidence of semi-permanent patches of cooler water off Durban, shown by airborne radiation thermometer surveys.
Eddies of a similar (?) nature associated with the Gulf Stream system have been described by Lee, T. N., dissertation, Florida State Univ. (1972).
