The aim of this study is to quantify the impact solar radiation management (SRM) might have on the large-scale drivers and characteristics of extreme weather events over southern Africa. The analysis perspective will be two-fold including an assessment of the climate drivers of the extreme events and (b) the implications of SRM for three critically important crops in the region. Extreme events are associated with particular synoptic-scale circulations and we will evaluate the ability of the global models to reproduce these synoptic states. Thereafter we will quantify projected changes in these circulations in the control and geoengineered simulation at the native spatial resolution. Extreme events are often local events that cannot be captured by low-resolution GCMs so we downscale these simulations dynamically and/or statistically to assess added value from the downscaling. Finally, we will quantify the impact of SRM on the climate suitability envelope for three important crops in the region (maize, wheat and sugar cane)
