| Abstract: | This low-spectrum model study on the multiple solutions to a nonlinear quasi-geostrophic oceanic current equation shows that
they depend on the combination ofRo, Re, λ and ε, that the bimodality of the Kuroshio depends strongly on the nonlinear effect represented byRo and λ, and that its occurrence probability is reduced by the dissipation represented byRe and ε. The stability of solutions is discussed in detail with Hurwitz's theory.
