A Thermal Oscillation Under a Restorative Forcing
Abstract
The authors report an interceded oscillation in a wind- and thermally-driven ocean general circulation model (OGCM). The oscillation is tantalizing in that it occurs under a relatively strong thermal damping (26.3 W m(exp-2)K(exp-1). Examinations involving a two-dimensional OGCM, a simple thermal flip-flop model and a three-dimensional OGCM with and without the nonlinear effect of temperature in the state equation of sea water demonstrate that the oscillation is not driven by mechanisms such as the so-called convective oscillator, or the advective overshooting oscillator.
