在大气环流的变化，产生干旱在南非进行了简要审查，因为也是在南部非洲周围的海洋均匀的海表温度变化的区域之间的联系和它们的相关性与降雨在南非。此后，海表温度异常场已知与干旱的发生被用来初始化的4级CSIRO大气环流气候模式，以模拟干旱在南非。模式的结果与以前发展的假设海洋-大气相互作用的区域，并表明是一致的，在许多重要方面的意见
Changes in atmospheric circulation that produce droughts over South Africa are briefly reviewed, as too are the links between regions of homogeneous sea surface temperature variation in the oceans around Southern Africa and their correlation with rainfall over South Africa. Thereafter sea surface temperature anomaly fields known to be linked to the occurrence of droughts are used to initialise the 4-level CSIRO general circulation climate model to simulate drought over South Africa. Model results are compared with previously developed hypotheses concerning ocean-atmosphere interactions in the region and are shown to be consistent with observations in many important respects
