The Lake Victoria Basin (LVB) in East Africa is very vulnerable to extreme weather events, like heavy precipitation, heat waves, droughts and wind storms. CORDEX Flagship Pilot Study (FPS) “ELVIC – climate Extremes in the Lake VICtoria basin” is an internationally coordinated program that brings together different regional climate models at convection permitting scale, performed by different research groups. Together, they want to answer following questions: (i) Are moist convective systems in Equatorial Africa better represented by convection permitting models (CPMs) compared to models that rely on a parametrization of convection? (ii) How can we best combine information of CMIP and CORDEX-Africa with CPM (climate change) integrations? (iii) How will extreme weather events evolve in the future in the LVB? (iv) How can improved probabilistic information on convective extremes be used by the impact community?
