| Zusammenfassung |
| The anticyclonic Loop Current Eddy (LCE) shedding events are strongly
associated with the evolution of Loop Current Frontal Eddies (LCFEs) over
the eastern Gulf of Mexico (GoM). A numerical simulation, in tandem with in situ
measurements and satellite data, was used to investigate the Loop Current
(LC) evolution and the surrounding LCFE formation, structure, growth and
migration during the Eddy Ekman and Eddy Franklin shedding events in the
summers of 2009 and 2010, respectively. During both events, northern GoM
LCFEs appeared vertically coherent to at least 1500 m in temperature
observations. They propagated towards the base of the LC, where, together
with the migration of Campeche Bank (southwest GoM shelf) eddies from south
of the LC, contributed to its "necking-down". Growth of Campeche Bank
LCFEs involved in Eddy Franklin was partially attributed to Campeche Bank
waters following upwelling events. Slope processes associated with such
upwelling included offshore exports of high positive potential vorticity
that may trigger cyclone formation and growth. The advection and growth of
LCFEs, originating from the northern and southern GoM, and their interaction
with the LC over the LCE detachment area favor shedding conditions and may
contribute to the final separation of the LCE. |
