Southern African rainfall physical mechanisms and projected Climate Change with a special focus on Zimbabwe
Aimed at understanding the physical mechanisms driving rainfall systems in southern Africa with a particular focus on Zimbabwe, this research is a step towards improving the representation of those systems in Climate Models leading to improved Rainfall projections. Because RCMs such as PRECIS are good at resolving subtle systems which modify local climates and possibly mask the anticipated anthropogenic induced (rainfall) change, its use in regions such as Zimbabwe that have complex terrain is crucial. Understanding the physical mechanisms that control rainfall in the current climate also provides insights into the changes being currently experienced in the region. It also enables analysis of the projected changes in circulation patterns that drive rainfall changes in the near future in addition to allowing stronger statements to be made on the expected longer term changes in rainfall. Thus paves leading to improved impact, vulnerability and adaptation studies as well integration of Climate Risk Management practices like Weather Index Insurance into development and economic planning.
