Abstract

To investigate chaos excitation and the relation of it to the stochastic synchronization phenomena in the oceanic double gyre, numerical simulations are conducted using 1.5 layer reduced gravity quasi-geostrophic model driven by seasonal changing forcing with red noise. Results show that by adding red noise to external forcing, synchronization occurs at smaller parameters than the parameter in which it can occur without noise (that is, stochastic synchronization occurs) and the transition to the direction of chaos excitation occurs at larger parameters.
