Using wavelet analysis and wavelet-based empirical orthogonal function analysis on scale-averaged-wavelet power and individual scale power, we identified the non-stationary sea-surface temperature (SST) fields of the South Atlantic and Indian Oceans that are associated with coherent regions of rainfall variability in central southern Africa (CSA). The(More)
Climate change exerts great influence on streamflow by changing precipitation, temperature, snowpack and potential evapotranspiration (PET), while human activities in a watershed can directly alter the runoff production and indirectly through affecting climatic variables. However, to separate contribution of anthropogenic and natural drivers to observed(More)
