Analysis of successive satellite thermal images in Tosa Bay, Japan, along the Kuroshio, showed that a cyclonic frontal eddy is formed due to the topographic effect of Cape Ashizuri when the Kuroshio axis moves offshore. Unlike those found in the South Atlantic Bight (SAB) along the Gulf Stream, the frontal shape induced by the eddy is asymmetric. Comparison with the previous description on the eddy in the SAB shows a possibility that cold, nutrient-rich deep water is not easily pumped up by the upwelling induced by the eddy in Tosa Bay and the surface temperature distribution is not affected much. Time series of water temperatures recorded on a ferryboat show that this phenomenon occurs about three times in a month but is not periodic. ¿ American Geophysical Union 1993
