The performance of three different vertical mixing schemes embedded in a global coarse resolution OGCM under both annual and monthly mean forcing are compared. These schemes are the integral model of Kraus and Turner and the differential parametrisations of Pacanowski and Philander and Henderson-Sellers (EDD1 scheme). The simulations of mean climatological conditions suggest that, with respect to climate change studies, the Kraus-Turner and the EDD1 schemes are overall more robust than the Pacanowski and Philander parametrisation. With respect to anomalous climatic conditions (i.e. decay of imposed SST anomalies), all three schemes indicate that the lifespan and penetration depth of a cold anomaly is somewhat greater than for a warm one. Also, the EDD1 scheme portrays the evolution process of the SST anomalies somewhat differently than the other two schemes.
