Research Staff

Sabina Abba Omar completed her PhD in Environmental and Geographical Science at the University of Cape Town, South Africa. Her PhD work focused on understanding the characteristics of cut-off lows, a synoptic system that can bring substantial rainfall to the Western Cape Region of South Africa. After completing her PhD she took up a postdoctoral position at the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy. There her work mainly involved analyzing regional climate model data from the CORDEX initiative and exploring whether the models are able to represent some aspects of the Southern African climate system. Currently she holds the position of research officer in the Climate System Analysis Group at the University of Cape Town where some of her research involves high resolution regional climate model simulations of urban cities for heat stress information, exploring the impacts of solar geo-engineering and delving into Southern African precipitation dynamics and their representation in climate models.
