On the behaviors of ocean bottom eddy
摘要
Abstract
On the basis of scaling analysis
this paper presents a frontal geostrophic dynamic system which can be used to describe the dynamics of an isolated bottom eddy and shows that five possible dynamic subregimes are included in the system. A particle-in-cell method is used to investigate the behavior of the eddy in the two dynamic subregimes
with 1) nonlinear effect (ε) relevant to the sloping bottom-induced beta effect (β 1) and 2) seamount-induced beta effect (β 2) dominant. In the dynamic subregime ofβ 1∼ε∼10-2 andβ 2=0
the eddy can keep as a whole for a long time and migrates for a long distance. In the dynamic subregime where the seamount-induced beta effect (β 1∼10-1) is dominant
the seamount traps the water particles
causing the eddy to break up into a discrete set of eddies moving around the seamount.
