We assessed the interannual variability and degree of similarity between the observed and model‐simulated temperature/rainfall using the Taylor diagram (Figure 4.6). It emerges that the experiments reproduce CC values between 0.6 and 0.9 for temperature and between 0.6 and 0.8 for rainfall in the Central African domain. MSEs are generally between 0.5 and 1.5 °C. As far as standard deviations are concerned, the results are heterogeneous. However, their values are around 1 °C in all seasons, with the slab‐ocean experiments closer to unity in the case of the whole of Central Africa and also for the NCA, EE, and SCA regions. It should be noted that in the WE region, which is closer to the Atlantic Ocean and therefore strongly influenced by its dynamic system, the two experiments in the model show particularly poor performance. This can be attributed to the fact that the parameterization of the slab‐ocean, which is only a simple approximation of the ocean dynamics, fails to reduce the bias of the SST and thus reduce the high values of MSE and variability on the Atlantic coast.
