Variable North Pacific influence on drought in southwestern North America since AD 854

Subjects

Abstract

Precipitation in southwestern North America has exhibited significant natural variability over the past few thousand years1. This variability has been attributed to sea surface temperature regimes in the Pacific and Atlantic oceans, and to the attendant shifts in atmospheric circulation patterns1,2. In particular, decadal variability in the North Pacific has influenced precipitation in this region during the twentieth century3,4, but links to earlier droughts and pluvials are unclear. Here we assess these links using δ18O data from a speleothem from southern California that spans AD 854–2007. We show that variations in the oxygen isotopes of the speleothem correlate to sea surface temperatures in the Kuroshio Extension region5 of the North Pacific, which affect the atmospheric trajectory and isotopic composition of moisture reaching the study site. Interpreting our speleothem data as a record of sea surface temperatures in the Kuroshio Extension, we find a strong 22-year periodicity, suggesting a persistent solar influence6 on North Pacific decadal variability. A comparison with tree-ring records of precipitation1 during the past millennium shows that some droughts occurred during periods of warmth in the Kuroshio Extension, similar to the instrumental record4. However, other droughts did not and instead must have been influenced by other factors. Finally, we find a significant increase in sea surface temperature variability over the past 150 years, which may reflect an influence of greenhouse gas concentrations on variability in the North Pacific.
