Also included are Time series of proxy data used for the SRZ and WRZ reconstructions: SRZ_proxies_infilled: lag adjusted and infilled proxy data as used for the reconstructions SRZ_proxies_raw: raw (not infilled) but lag adjusted proxy data CLIWOC_DJF_SRZ: Time series of CLIWOC/ICOADS wind speed data used for the alternative SRZ reconstructions (See Supplementary Material Section S6). Also included are extended ensembles as follows: Ensemble of extended documentary data as described in the Supplementary Material (section S2). Each file contains 1000 realizations of documentary index time series prolonged to present. There is one file for each region and extension method. The files ending with "same.txt" are the ones that were used for the final reconstructions (see SM section S2). From these files, one time series is sampled as predictor for each of the 3000 reconstruction ensemble members (details see section S4). ABSTRACT SUPPLIED BY ORIGINATOR: This study presents the first consolidation of palaeoclimate proxy records from multiple archives to develop statistical rainfall reconstructions for southern Africa covering the last two centuries. State-of-the-art ensemble reconstructions reveal multi-decadal rainfall variability in the summer and winter rainfall zones. A decrease in precipitation amount over time is identified in the summer rainfall zone. No significant change in precipitation amount occurred in the winter rainfall zone, but rainfall variability has increased over time. Generally synchronous rainfall fluctuations between the two zones are identified on decadal scales, with common wet (dry) periods reconstructed around 1890 (1930). A strong relationship between seasonal rainfall and sea surface temperatures (SSTs) in the surrounding oceans is confirmed. Coherence among decadal-scale fluctuations of southern African rainfall, regional SST, SSTs in the Pacific Ocean and rainfall in south-eastern Australia suggest SST-rainfall teleconnections across the southern hemisphere. Temporal breakdowns of the SST-rainfall relationship in the southern African regions and the connection between the two rainfall zones are observed, for example during the 1950s. Our results confirm the complex interplay between large-scale teleconnections, regional SSTs and local effects in modulating multi-decadal southern African rainfall variability over long timescales.
