This paper contributes to the understating of tornadoes in South Africa using case study analysis. In South Africa tornadoes are the recurring phenomenon (the climatology) but they have received less attention. Damages from storms itself (tornadoes inclusive) are significant in South Africa relative to other weather-related disasters for example floods, heat waves, and droughts. Case study approach was adopted in the current study. Data were in the courtesy of the following, National Oceanic and Administration (NOOA), National Centers for Environmental Protections (NCEP), Eumetsat, and South African weather Service. The aim of the study was to provide an overview of the occurrence of tornadoes in South Africa using a case study. From the case study analysis, the tornadoes at Klerksdorp on March 4, 2007, was associated with the cold frontal systems and the cut-ff low (extratropical circulation) which were the dominant weather systems of the day. Case study approach may be the best way to study events of these nature for a more informed decision, for example, issuing an early warning system. Case studies, for example, involving interaction between extratropical and tropical circulation may be also more informative.
