Identifying the roles of the ocean and atmosphere in creating a rapid equatorial response to a Southern Ocean anomaly

Recent research has identified a rapid ocean response mechanism to salinity anomalies in the Southern Ocean using an idealised ocean model. Here we examine the relative importance of the ocean and atmosphere in creating an equatorial response to a Southern Ocean anomaly. Using a coupled climate mode...
