Author:Davis, C; Joubert, ADate:Nov 2011Southern Africa is a predominantly semi-arid region with high rainfall variability, characterised by frequent droughts and floods. It is also widely recognised as one of the most vulnerable regions to climate change because of low levels of ...Read more
Author:Fauchereau, N; Pohl, B; Monteiro, Pedro MS; Reason, CDate:Sep 2009In this study the authors investigate in particular its links with the Madden Julian Oscillation and ENSO, the dominant modes of tropical atmospheric variability at the intraseasonal and interannual timescales, respectively. It is showed here ...Read more
Author:Beraki, Asmerom F; Landman, WA; DeWitt, DDate:Sep 2012Southern Hemisphere (SH) climate variability has been the focus of several researchers (e.g., Wallace and Hsu, 1983). According to these early studies, the SH is characterized by quasistationary oscillations and zonally propagating waves in ...Read more
Author:SANCOR; SASCARDate:May 1979South African research in the Southern Ocean has already produced some important and illuminating results. Most of these efforts, however, were of an individual and uncoordinated nature. Due to increasing interest in the ocean- in South Africa ...Read more
Author:Kellett, BJ; Griffin, DK; Bingham, R; Campbell, RNDate:Apr 2008Hybrid space propulsion has been a feature of most space missions. Only the very early rocket propulsion experiments like the V2, employed a single form of propulsion. By the late fifties multi-staging was routine and the Space Shuttle employs ...Read more
