Oceanic oscillation phenomena related synchronization and stochastic resonance

Abstract eng:
Various oscillation phenomena, such as the transitions between stable and unstable states of western boundary currents (e.g., the Kuroshio), are present in the oceanic circulation of the North Pacific Ocean. These phenomena are considered to be related to non-linear rhythmic phenomena, such as the synchronization and the stochastic resonance, which are often observed in non-linear ocean systems. However, oceanic applications of these non-linear rhythmic phenomena have not been investigated in detail. Thus, we investigated the responses of oceanic double gyres to external wind forcing with and without noise using a 1.5 layer quasi-geostrophic model and considered the possibility of the occurrence of these non-linear rhythmic phenomena in general oceanic circulation.
