  • Africa and the Paris Agreement 
    Kruger, Andries C. (Nature Publishing Group, 2018-05)
    The African continent is one of the most vulnerable regions to future climate change. Research now demonstrates that constraining anthropogenic warming to 1.5 °C instead of 2 °C will significantly lower the risk of heatwaves ...
  • Changes in extreme daily rainfall characteristics in South Africa : 1921–2020 
    McBride, Charlotte M.; Kruger, Andries; Dyson, Liesl L. (Elsevier, 2022-12)
    Many areas in South Africa are prone to localized flooding. With climate change already said to affect the intensity of rainfall, there is a need to investigate if there is a change in the probability of significant to ...
  • Development of an updated fundamental basic wind speed map for SANS 10160-3 
    Kruger, Andries C.; Retief, J.V.; Goliger, A.M. (South African Institution of Civil Engineering, 2017-12)
    This paper evaluates the need for updating the strong wind climate stipulations of South Africa for the design of structures in accordance with SANS 10160-3:2010, as based on the latest information presented by Kruger ...

    Dunn, Robert J.H.; Alexander, Lisa V.; Donat, Markus G.; Zhang, Xuebin; Bador, Margot; Herold, Nicholas; Lippmann, Tanya; Allan, Rob; Aguilar, Enric; Barry, Abdoul Aziz; Brunet, Manola; Caesar, John; Chagnaud, Guillaume; Cheng, Vincent; Cinco, Thelma; Durre, Imke; De Guzman, Rosaline; Htay, Tin Mar; Wan Ibadullah, Wan Maisarah; Bin Ibrahim, Muhammad Khairul Izzat; hoshkam, Mahbobeh K; Kruger, Andries C.; Kubota, Hisayuki; Wee Leng, Tan; Lim, Gerald; Li‐Sha, Lim; Marengo, Jose; Mbatha, Sifiso; McGree, Simon; Menne, Matthew; De los Milagros Skansi, Maria; Ngwenya, Sandile; Nkrumah, Francis; Oonariya, Chalump; Pabon‐Caicedo, Jose Daniel; Panthou, Geremy; Pham, Cham; Rahimzadeh, Fatemeh; Ramos, Andrea; Salgado, Ernesto; Salinger, Jim; Sane, Youssouph; Sopaheluwakan, Ardhasena; Srivastava, Arvind; Sun, Ying; Timbal, Bertrand; Timbal, Bertrand; Trachow, Nichanun; Trewin, Blair; Van der Schrier, Gerard; Vazquez‐Aguirre, Jorge; Vasquez, Ricardo; Villarroel, Claudia; Vincent, Lucie; Vischel, Theo; Vose, Russ; Bin Hj Yussof, Mohd Noor'Arifin (American Geophysical Union, 2020-07-02)
    We present the second update to a data set of gridded land‐based temperature and precipitation extremes indices: HadEX3. This consists of 17 temperature and 12 precipitation indices derived from daily, in situ observations ...
  • Historical and projected trends in nearsurface temperature indices for 22 locations in South Africa 
    Kruger, Andries C.; Rautenbach, Hannes; Mbatha, Sifiso; Ngwenya, Sandile; Makgoale, Thabo E. (Academy of Science of South Africa, 2019-05-29)
    Motivated by the risks posed by global warming, historical trends and future projections of near-surface temperature in South Africa have been investigated in a number of previous studies. These studies included the ...
  • Historical rainfall trends in South Africa : 1921–2015 
    Kruger, Andries C.; Nxumalo, M.P. (Water Research Commission, 2017-04)
    The aim of this study is to update the analysis of historical rainfall trends with reference to the work from previous studies, through optimizing the highest spatial resolution with the longest possible period of analysis, ...
  • Is the summer season losing potential for solar energy applications in South Africa? 
    Singh, Jyotsna; Kruger, Andries C. (The Research Energy Centre of the University of Cape Town, 2017-05)
    Seasonal trends using in situ sunshine duration (SD) and satellite, incoming shortwave solar radiation (SIS) data for South Africa over a period up to six decades were investigated. Trend analysis was applied to SD ...
  • Precipitation from persistent extremes is increasing in most regions and globally 
    Du, Haibo; Alexander, Lisa V.; Donat, Markus G.; Lippmann, Tanya; Srivastava, Arvind; Salinger, Jim; Kruger, Andries C.; Choi, Gwangyong; He, Hong S.; Fujibe, Fumiaki; Rusticucci, Matilde; Nandintsetseg, Banzragch; Manzanas, Rodrigo; Rehman, Shafiqur; Abbas, Farhat; Zhai, Panmao; Yabi, Ibouraïma; Stambaugh, Michael C.; Wang, Shengzhong; Batbold, Altangerel; De Oliveira, Priscilla Teles; Adrees, Muhammad; Hou, Wei; Zong, Shengwei; Santos e Silva, Claudio Moises; Lucio, Paulo Sergio; Wu, Zhengfang (Wiley, 2019-06-16)
    Extreme precipitation often persists for multiple days with variable duration but has usually been examined at fixed duration. Here we show that considering extreme persistent precipitation by complete event with variable ...
  • Predominant atmospheric and oceanic patterns during coastal marine heatwaves 
    Schlegel, Robert W.; Oliver, Eric C.J.; Perkins-Kirkpatrick, Sarah; Kruger, Andries C.; Smit, Albertus J. (Frontiers Media, 2017-10-12)
    As the mean temperatures of the worlds oceans increase, it is predicted that marine heatwaves (MHWs) will occur more frequently and with increased severity. However, it has been shown that variables other than increases ...
  • Review of climatic input data for wind load design in accordance with SANS 10160-3 
    Goliger, A.M.; Retief, J.V.; Kruger, Andries C. (South African Institution of Civil Engineering, 2017-12)
    With the publication of Part 3 Wind Actions of the South African Loading Code SANS 10160:2010, several issues concerning adjustments from the reference standard Eurocode EN 1991-1-4:2004 could not be resolved due to lack ...
  • Surface temperature trends from homogenized time series in South Africa : 1931-2015
