Author:Thomalla, Sandy J; Nicholson, Sarah-Anne; Ryan-Keogh, Thomas J; Smith, Marie EDate:Aug 2023Climate change is expected to elicit widespread alterations to nutrient and light supply, which interact to influence phytoplankton growth and their seasonal cycles. Using 25 years of satellite chlorophyll a data, we show that large regions ...Read more
Author:Mredlana, Prince; Naidoo, Darryl; Mafusire, C; Kruger, T; Dudley, Angela L; Forbes, ADate:Jul 2016Optical field characterisation often requires various isolated experiments to obtain characterisation parameters, we investigate a novel approach to characterise an optical field employing a Wigner distribution function with a modal decomposition ...Read more
Author:Goliger, Adam; Van Wyk, Ters; Bradley, RA; Bilse, D; Ruthenavelu, MDate:Aug 2016All South African harbours are exposed to large-scale frontal/strong synoptic weather events and some also experience, less frequently, short duration convective activity. These often result in operational stoppages, delays in loading/unloading ...Read more
Author:Bofinger, S; Zimmermann, B; Gerlach, A-K; Bischof-Niemz, TobiasDate:Mar 2016CSIR, SANEDI, Eskom and Fraunhofer IWES conducted a study to holistically quantify the wind-power potential in South Africa, and the portfolio effects of widespread spatial wind and solar power aggregation in South Africa. Key result: South ...Read more
Author:Mabille, EDate:Oct 2015Why is a wind atlas important for South Africa? This presentation recommends that a dedicated wind energy measurement programme needs to be undertaken to confirm the true wind energy potential in South Africa.Read more
Author:Szewczuk, S; Prinsloo, FWDate:31 Aug 2010The goal of the South African Wind Energy Programme (SAWEP) is to reduce greenhouse gas emissions generated by thermal power in the national inter-connected system. SAWEP has six main expected outcomes: increased public sector incremental ...Read more

Author:Szewczuk, SDate:Aug 2010Africa is intended to accelerate the investment in wind energy in South Africa. This is in line with government’s objectives of reducing green house gases and diversifying our energy supply and also developing human capacity to support the ...Read more
Author:Kekana, H; Landwehr, Gregory BDate:Jun 2019The wind capacity factor calculator is developed to perform two main tasks: to estimate the annual energy production from the wind resource at any location in South Africa, and to compare the two datasets used in its operation with standard ...Read more
Author:Roualt, M; Backeberg, BjörnDate:Oct 2016Sea-surface temperature (SST), altimetry derived sea-level anomalies (SLA) and surface current are used south of the Agulhas Current to identify warm core mesoscale ocean eddies presenting a distinct SST perturbation superior to 1(supo)C to ...Read more
Author:Rouault, Marjolaine J; Verley, P; Backeberg, Bjorn-ChristophDate:2016Sea surface temperature (SST) estimated from the Advanced Microwave Scanning Radiometer E onboard the Aqua satellite and altimetry-derived sea level anomalies are used south of the Agulhas Current to identify warm-core mesoscale eddies ...Read more
Author:Karamanski, Stefan; Erfort, GDate:Apr 2023South Africa’s energy network is under severe pressure due to low supply and overwhelming demand. With an increase in renewable energy providers, specifically wind energy, knowing how the supply can satisfy the electricity demand may relieve ...Read more
Author:Domingues, R; Goni, G; Swart, S; Dong, SDate:Feb 2014The variability of the Antarctic Circumpolar Current (ACC) system is largely linked to the atmospheric forcing. The objective of this work is to assess the link between local wind forcing mechanisms and the variability of the upper-ocean ...Read more
Author:Roos, THDate:May 2012One of the design requirements of a heliostat is the ability to withstand storm wind loads in the stow position and operational wind loads in any position. To design a heliostat, therefore, one must be able to predict the wind loading on the ...Read more
