Francis Nkrumah (PhD) I am a distinguished climate scientist, lecturer at the University of Cape Coast, Ghana, and an African contributing author to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). With a PhD in Physics, I specialize in regional climate modelling, mesoscale convective systems, and West African Monsoon dynamics under climate change. As a dedicated educator and mentor, I have experience in teaching meteorological and physics courses, contributing to shaping the next generation of scientists. I have expertise and community engagement, combined with his role in IPCC AR6, underscore his commitment to advancing climate science and addressing pressing global environmental challenges. |

ResearchMy research interests encompass regional climate modelling, mesoscale convective systems, and the dynamics of the West African Monsoon under climate change. I focus on extreme weather events such as droughts and high-intensity precipitation, as well as tropical meteorology and atmospheric physics. Additionally, I am interested in innovative approaches to addressing climate change, including solar radiation modification and carbon dioxide removal, with a particular emphasis on their regional implications in West Africa.
