Strain Evolution and Instability of an Anticyclonic Eddy From a Laboratory Experiment

Résumé

Using the 13 m diameter LEGI-Coriolis rotating platform, the evolution processes of a generated anticyclonic eddy throughout its lifecycle are analyzed. Experimental results have shown that the eddy lasted for approximately 3 T 0 , where T 0 is the rotating period of 90 s. After T = 0.3 T 0 , the eddy enters its mature phase, whereby following this event, eddy intensity slowly decreases from its maximum rotation speed. By T = 2.6 T 0 , the eddy enters a stage of rapid weakening. In its decay period, two underlying mechanisms for this decay have been identified as inertial instability and eddy–eddy interactions.
