Correlation Analysis between Anomalies of Selected Components of the Freshwater Budget and the SPEI-1 Time Series for SSA during 1980-2015

 

Table 1. Pearson correlation coefficients between the time series of SPEI-1  and evaporation, moisture uptake and moisture supply over RR.  Data: GLEAM 3.1a for terrestrial evaporation and OAFLUX for oceanic evaporation.
