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)
Wavelet-based empirical orthogonal function ͑WEOF͒ analysis was used to analyze the nonstationary spatial, temporal, and frequency regimes of the regional variability in southern African summer ͑October–March͒ rainfall. The leading modes of rainfall variability were then used to establish associations with gridded scale-averaged wavelet power of the sea(More)
