Dell Technologies HPC Community Event
About the Event
Forecasting weather with a lead time of beyond two hours requires the use of numerical weather and climate models. These models are based on conservation of momentum, energy and mass, as well as the equation of state. The models are generally split into grid boxes, with calculations made at the edges of the grid boxes, where lines of latitude and longitude meet. The smaller the grid box, the higher the resolution. High Performance Computing (HPC) makes it possible for numerical weather and climate models to run with high resolution using domain decomposition to split the work up to run on different nodes. Output from weather and climate models is used to develop products for climate sensitive sectors such as agriculture, water, energy, health, marine and energy. The presentation will focus on work conducted by the South African Weather Service (SAWS) researchers, and how the in-house HPC system and the Centre For High Performance Computing (CHPC) cluster are used for research and operations in Numerical Weather Prediction. The entity also has a Marine Research Unit which runs a set of coupled coastal wave and hydrodynamic models both operationally at the SAWS as well as on the CHPC cluster to support research efforts. The presentation will also cover this unit’s efforts in supporting South Africa’s maritime forecasting capabilities and some of the research projects currently underway utilizing CHPC computational resources.
About the Speakers
Dr. Michael Barnes, Scientist: Marine Unit, South African Weather Service
Michael is a meteorologist working in the Marine Unit of the South African Weather Service (SAWS). His focus is on the development of operational coastal wave and water level forecast systems, and the basic research underpinning them. Michael leads operations of the marine operational modelling infrastructure of the SAWS Marine Unit since its inception in 2018. He also currently acts as the METAREA VII Coordinator. Michael has a strong background in meteorological processes in both operations and research. He spent the beginning of his career as an operational meteorologist and weather forecaster. Michael’s atmospheric research focus is on dynamical processes. He has a PhD Meteorology degree specialising in synoptic, atmospheric dynamical processes and has published extensively on the topic in Q1, peer reviewed journals.
Dr. Mary-Jane Bopape, Senior Manager: Research, South African Weather Service
Mary-Jane Bopape is a Senior Sanager: Research at the South African Weather Service. She holds a PhD degree in meteorology from University of Pretoria, and has worked as a Postdoctoral Research Fellow at the University of Reading. She also worked at the Council for Scientific and Industrial Research (CSIR) Natural Resources and Environment (NRE) and Centre for High Performance Computing (CHPC) with a focus on climate change studies. She is part of the third cohort of the African Institute for Mathematical Sciences (AIMS) and Next Einstein Initiative (NEI) Fellowship Program for Women in Climate Change Science. She is leading a weather and climate project to assist with the implementation of the SADC Cyber-Infrastructure Framework. She is a 2019 Climate Research for Development (CR4D) fellowship grantee. She was recognized by the President of South Africa as a pathfinder in his August 9th, 2019 speech on Women’s Day. She is a co-recipient of the 2008 World Meteorological Organization (WMO) award for young researchers.
