A simple model was constructed to study the effects of a wind-driven ocean gyre on the thermohaline overturning circulation. It was found that the presence of a surface gyre allows for stable (self-sustained) oscillations about a mean state characterized by high-latitude deep-water formation regions. The gyre transport had a negative feedback that eliminates the advective instability, allowing for self-sustained thermohaline variability.

Abstract
A simple model was constructed to study the effects of a wind-driven ocean gyre on the thermohaline overturning circulation. It was found that the presence of a surface gyre allows for stable (self-sustained) oscillations about a mean state characterized by high-latitude deep-water formation regions. The gyre transport had a negative feedback that eliminates the advective instability, allowing for self-sustained thermohaline variability.
