NITheCS colloquium, presented by Prof Francois Engelbrecht (Global Change Institute, University of the Witwatersrand)

View Invitation

Dynamic climate models have become the main tools to generate detailed projections of future climate change, either globally when applied as global climate models (GCMs), or regionally when applied over limited areas of interest as regional climate models (RCMs). Very similar models are also applied for short-range numerical weather prediction (NWP). Both fields (NWP and dynamic climate modelling) are currently responding to new computing architectures that make feasible the integration of models using hundreds of thousands of cores, or even a million cores, for single ultra high-resolution simulations.

In this talk, Prof Francois Engelbrecht will talk about this new frontier in climate modelling: convective-scale or cloud-resolving modelling on massively parallel computing systems. He will also suggest methodologies through which African-based scientists working in the computational climate sciences can undertake competitive research on smaller (yet still powerful) computational resources such as the Lengau cluster of the CHPC. He will highlight some currently running climate modelling experiments at the GCI, undertaken as part of the WITS Global Change Institute’s research programme of building an African-based Earth System Model.
