The feasibility of reconstructing hydroclimate over West Africa using tree-ring chronologies in the Mediterranean region

Abstract Dendrochronology in West Africa has not yet been developed despite encouraging reports suggesting the potential for long tree-ring reconstructions of hydroclimate tropics. This paper shows that even absence local tree chronologies, it is possible to reconstruct a region using remote rings. We present Sub-Saharan Drought Atlas (WSDA), new paleoclimatic reconstruction African based on chronologies from Mediterranean Region, made by teleconnected climate relationship between Monsoon and Sea surface temperatures. The WSDA one-half degree gridded summer Palmer Severity indices 1500 2018 CE, produced ensemble point-by-point regression. Calibration verification statistics indicate significant skill over most its domain. three leading modes variability are accurately reproduced WSDA, demonstrating strong compared regional instrumental precipitation drought indices. can be used study outside limit longest observed record integration comparison with other proxy archaeological data. It also an essential first step toward developing Africa’s hydroclimate.
