| Sumario: | Analysis of observations of the Loop Current (LC) northward penetration and LC area, from satellite seasurface temperature, Topex/Poseidon (TP) sea surface height anomaly, and results from numerical simulationsshows that when a relatively large cyclone remains north of the LC, the shedding period between twoconsecutive eddies may increase. It is shown that the interaction between the LC and the cyclone producesleakage of mass from the current and pushes the LC towards the West Florida Shelf escarpment, where mass is also redistributed due to the generation of a pressure gradient and a jet along the shelf edge. This processdelays the northward penetration of the LC and the enlargement of its area, increasing the time between eddyshedding. This happened in 1998, when the largest registered period between eddy shedding since 1973occurred, and the largest cyclone of the TP era was north of the LC. |
