The all-year rainfall region of South Africa: Satellite rainfall-estimate perspective

Author: Engelbrecht, CJ ; Landman, WA ; Engelbrecht, FA Date: Sep 2012 Climate predictability and variability studies over South Africa typically focus on the summer rainfall region and to a lesser extent on the winter rainfall region. The all-year rainfall region of South Africa, a narrow strip located along ... 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 ...

The bi-decadal rainfall cycle, Southern Annular Mode and tropical cyclones over the Limpopo River Basin, southern Africa

Author: Malherbe, Johan ; Landman, WA ; Engelbrecht, FA Date: Jun 2014 The association between bi-decadal rainfall variability over southern Africa and the rainfall contributed by tropical cyclonic systems from the Southwest Indian Ocean (SWIO) provides a potential means towards understanding decadal-scale ...

Design and construction of sustainable climate resilient rural access road infrastructures

Author: Komba, Julius J ; Langa, R ; Paige-Green, P ; Verhaeghe, Benoit MJA ; Mokoena, Refiloe Date: Dec 2021 The chapter is organized and structured as follows; the introduction section is followed by an overview of climate change-related challenges affecting Mozambique. The study methodology (approach) is then described, followed by a discussion ... Read more
Sea-air CO2 fluxes in the Southern Ocean for the period 1990-2009

Author: Lenton, A ; Tilbrook, B ; Law, RM ; Bakker, D ; Doney, SC ; Gruber, N ; Ishii, M ; Hoppema, M ; Lovenduski, NS ; Matear, RJ ; McNeil, BI ; Metzl, N ; Mikaloff Fletcher, SE ; Monteiro, Pedro MS ; Rodenbeck, C ; Sweeney, C ; Takahashi, T Date: 2013 The Southern Ocean (44–75° S) plays a critical role in the global carbon cycle, yet remains one of the most poorly sampled ocean regions. Different approaches have been used to estimate sea–air (sub2) fluxes in this region: synthesis of surface ... Read more
Seasonal cycle of N:P:TA stoichiometry as a modulator of CO2 buffering in eastern boundary upwelling systems

Author: Gregor, L ; Monteiro, Pedro MS Date: Oct 2013 In this study we use the southern Benguela upwelling system to investigate the role of nutrient and carbon stoichiometry on carbonate dynamics in eastern boundary upwelling systems. Six months in 2010 were sampled along a cross-shelf transect. ... Read more
Seasonal prediction for Southern Africa: Maximising the skill from forecast systems

Author: Landman, WA Date: Jun 2012 The development of seasonal forecast systems for southern Africa is presented, followed by the justification why certain model configurations have been selected in order to optimise seasonal forecast performance. The skill of the HadGEM3 ... Read more
The sensitivity of primary productivity to intra-seasonal mixed layer variability in the sub-Antarctic Zone of the Atlantic Ocean

Author: Joubert, WR ; Swart, S ; Tagliabue, A ; Thomalla, Sandy J ; Monteiro, Pedro MS Date: Mar 2014 The seasonal cycle of primary productivity is impacted by seasonal and intra-seasonal dynamics of the mixed layer through the changing balance between mixing and buoyancy forcing, which regulates nutrient supply and light availability. Of ... Read more
Southern hemisphere climate variability as represented by an ocean-atmosphere coupled model

Author: Beraki, Asmerom F ; Landman, WA ; DeWitt, D Date: Sep 2012 Southern 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
Wind changes above warm Agulhas Current eddies

Author: Rouault, Marjolaine J ; Verley, P ; Backeberg, Bjorn-Christoph Date: 2016 Sea 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 ...
