1414 JOURNAL OF CLIMATE VOLUME 16 Shift in ENSO Teleconnections Recorded by a Northern Red Sea Coral
El Niño–Southern Oscillation (ENSO) teleconnections over Europe and the Middle East are evaluated using an oxygen isotope coral time series from the northern Red Sea and various instrumental datasets. A shift in the correlation between the Niño-3 index and the Red Sea coral record in the 1970s is de...
