Moisture Sources for Precipitation in Southern Africa
Bachelor of Science (B.Sc.)
Precipitation and thus water availability in Southern Africa are subject to strong fluctuations on climatological time scales. In order to improve our understanding of the underlying atmospheric processes, but also to provide the methodological basis for isotope-based, paleoclimatological reconstructions of these fluctuations (e.g. Schmidt et al., 2017), this work will investigate the moisture sources of precipitation. For this purpose, backward trajectories are calculated for a period of several years and the moisture sources are reconstructed (see e.g. Sodemann and Zubler, 2010). The results can then be interpreted in the context of a collaboration with the Institute of Geological Sciences, which is concerned with the analysis of the isotope composition of precipitation and climate reconstructions based on it.
Prerequisites for this work are an interest in climatological analyses of large data sets and interdisciplinary work in the field of paleoclimatology.
