✦ Synopsis
Time series (scores) of rainfall from cloud bands across South Africa, generated through S-mode principal component analysis, are compared with equivalent estimated time series developed from satellite imagery and surface data. The cloud bands, which link the tropical and temperate circulations, accounted for the highest explained rainfall variance over the interior of South Africa in the principal component analysis. For most summer months the principal component scores are useful first approximations to the true time series.
