| contents | A 245-year coral oxygen isotope record from the northern Red Sea (Ras Umm Sidd/Egypt, ~28°N) in bimonthly resolution is presented. The mean annual coral delta18O signal apparently reflects varying proportions of both sea surface temperature and delta18Oseawater variability. In conjunction with instrumental observations of climate the coral record suggests for interannual and longer timescales that colder periods are accompanied by more arid conditions in the northern Red Sea but increased rainfall in the southeastern Mediterranean, whereas warmer periods are accompanied by decreased rainfall in the latter and less arid conditions in the northern Red Sea. A ~70-year oscillation of probably North Atlantic origin dominates the coral time series. Interannual to interdecadal variability is correlated with instrumental indices of the North Atlantic Oscillation (NAO), the El Niño-Southern Oscillation (ENSO), and North Pacific climate variability. The results suggest that these modes contributed consistently to Middle East climate variability since at least 1750, preferentially at a period of ~5.7 years. |
