Antarctic stratospheric ozone and seasonal predictability over southern Africa

Author: Engelbrecht, FA ; Ndarana, T ; Morioka, Y ; Behera, S ; Thatcher, M ; McGregor, JL Date: Sep 2015 The impact of time-varying Antarctic stratospheric ozone on southern African summer climate variability is explored through atmospheric global circulation model (AGCM) sensitivity experiments. A control experiment following the design of the ... Read more
Anthropogenic radiative forcing of southern African and Southern Hemisphere climate variability and change

Author: Engelbrecht, FA ; Landman, WA ; Ndarana, T Date: Oct 2014 This paper explores the hypothesis that the more realistic depiction of the atmosphere's ability to absorb and release radiation in atmospheric model simulations, through the more realistic representation of the time-varying concentrations ...

Impact of lower stratospheric ozone on seasonal prediction systems

Author: Mathole, K ; Ndarana, T ; Beraki, Asmerom F ; Landman, WA Date: 2014 We conducted a comparison of trends in lower stratospheric temperatures and summer zonal wind fields based on 27 years of reanalysis data and output from hindcast simulations using a coupled ocean atmospheric general circulation model (OAGCM). ...

Integrated climatology and trends in the subtropical Hadley cell, sunshine duration and cloud cover over South Africa

Author: Mahlobo, DD ; Ndarana, T ; Grab, S ; Engelbrecht, Francois Date: Dec 2018 This study uses two methods to diagnose the local Hadley circulation; first the zonally averaged mass stream function, and second the stream function vector method. The two methods have been applied to the ERA-Interim reanalysis data for the ... Read more
