Climate and Circulation Changes in Southern Africa (already finished)

Still many economies in southern Africa are dominated by agriculture, which strongly depends on rainfall. Climate variations in semiarid regions have a strong socioeconomic impact, because of large populations and limited natural resources. Understanding of past climate variations has a high value for the prediction of future climate, seasonal forecast and the crop and water management. Meanwhile climatic data are already used to predict cropyield and to reduce the vulnerability by droughts.

The present study intends to contribute to the understanding of climate trends, changes and variability in southern Africa during the past 100 years. Analyses of atmospheric circulation changes and couplings with sea-surface temperatures are one main part of this Ph.D Thesis, which is embedded in the DFG-post-graduate program "Joint Geoscientific Research in Africa".
