Three-year running mean significantly correlated to SST Nino 4 region
There is no significant relationship between stable isotopes and precipitation (net accumulation) on the Quelccaya ice cap. In other words, the precipitation “amount effect” does not appear to govern the stable isotopic chemistry on this tropical glacier. Because 70 to 80% of the precipitation falling on Quelccaya arrives during the wet season, the δ18O history reflects primarily conditions during austral summer. Decadal averages of precipitation amount and δ18O are not strongly related
