| 摘 要： | I~IOXSatellite infrared measurements are now accepted as an effeCtive way of mapping sea surfacetemperature (SST) distributions on global and regional scales. While regional SST maps are widely uest as background data for oceanographic experiments, they tend to be considered by oceanographers as at best qualitative tools. There is SCOPe for developing the use of satellite SST imagesac extensively for the study of mesoscale d~ical processes, as this paper seeks to demonstrate. As Part O…

| Abstract: | Two kinds of eddies in the Bay of Biscay were observed in 1990 by the use of satellite imagery and in-situ measurements. Frontal eddies in the warm winter current off the north coast of Spain persist for about 3 months and have a vertical scale of 700 m and diameters of 80 to 150 km. According to our interpretation, these eddies are mainly generated by baroclinic instability of the warm winter current. The anticycolonic eddy at the Jovellanco Seamount is about 200 km in scale and has a lifetime of 7 months. The possible mechanics for the generation of the eddy are baroclinic instability of the mean current, topographic interaction and atmospheric forcing. |
