Abstract:
On the basis of the inductive analysis of observation and calculation results, this paper presents a motion instability formation mechanism of the multi-core structure of the East China Sea Kuroshio. This theoretical work includes presentation of the simplified model, derivation of the existence condition of the instable solution and some scaling estimation of the multi-core structure. Theoretical results are in good consistence with the observations.
