  • Attributes of cut-off low induced rainfall over the Eastern Cape Province of South Africa 
    Molekwa, Samuel; Engelbrecht, Christina Johanna; Rautenbach, Cornelis Johannes de Wet (Springer, 2014-10)
    Cut-off low (COL) weather systems that are associated with rainfall over the Eastern Cape are considered in this study. COLs are objectively identified and tracked over a 31-year period. Daily rainfall data of 22 evenly ...
  • Cut-off lows in the Southern Hemisphere and their extension to the surface 
    Barnes, Michael A.; Ndarana, Thando; Landman, Willem Adolf (Springer, 2021-06)
    Many cut-off low (COL) climatologies have been done throughout the Southern Hemisphere. Few have focused on COL vertical depth and their link to surface cyclones that often accompany these systems. Here we extend these ...
  • Cut-off lows over South Africa : a review 
    Xulu, Nkosinathi G.; Chikoore, Hector; Bopape, Mary-Jane M.; Ndarana, Thando; Muofhe, Tshimbiluni P.; Mbokodo, Innocent L.; Munyai, Rendani B.; Singo, Mukovhe V.; Mohomi, Tumelo; Mbatha, Sifiso M.S.; Mdoka, Marshall L. (MDPI, 2023-03-05)
    Every year, cut-off low (COL) pressure systems produce severe weather conditions and heavy rainfall, often leading to flooding, devastation and disruption of socio-economic activities in South Africa. COLs are defined ...
  • Downstream development during ridging South Atlantic Ocean anticyclones 
    Ndarana, Thando; Lekoloane, Lesetja E.; Rammopo, Tsholanang S.; Reason, Chris J.C.; Chikoore, Hector; Engelbrecht, Francois A. (Springer, 2023-09)
    Ridging South Atlantic high pressure systems (ridging highs) are often accompanied by cut-off low (COL) pressure systems aloft, but may also occur without them, in which case a linear baroclinic wave would be observed ...
  • Forecasting intense cut-off lows in South Africa using the 4.4 km unified model 
    Muofhe, Tshimbiluni Percy; Chikoore, Hector; Bopape, Mary-Jane Morongwa; Nethengwe, Nthaduleni Samuel; Ndarana, Thando; Rambuwani, Gift Tshifhiwa (MDPI, 2020-11)
    Mid-tropospheric cut-off low (COL) pressure systems are linked to severe weather, heavy rainfall and extreme cold conditions over South Africa. They occur during all the above and often result in floods and snowfalls during ...
  • A quasi-geostrophic diagnosis of the zonal flow associated with cut-off lows over South Africa and surrounding oceans 
    Ndarana, Thando; Rammopo, Tsholanang S.; Chikoore, Hector; Barnes, Michael A.; Bopape, Bopape, M.J. (Springer, 2020-11)
    The zonal flow associated with cut-off lows (COLs) comprises two jet streaks of different spatial extents. The smaller scale jet streak, located north of the COLs, forms as a result of meridional divergence of vorticity ...
