  • South Africa is already hydrologically vulnerable and this is likely to be exacerbated by both nonpermanent ENSO-related as well as more permanently greenhouse-gas forced climate changes. Climate change effects are explained by way

  • This article provides a critical assessment of the techniques and approaches to modelling regional climate and climate change and their application in southern Africa. Particular attention will be given to addressing uncertainties associated
  • with modelling regional climate and their effect on developing regional climate change scenarios.

  • Climatic variability and change over southern Africa : a reflection on underlying processes
  • of the region during the twentieth century is described. The atmospheric characteristics of wet and dry years are then described and related to changes in the disposition of major rain-producing weather systems. Finally, evidence for long-term trends
