basis: The range of the observed 18O cyclicity, 3a€“5a€°, is approximately equal to the annual range of observed rainfall d18O values (IAEA/WMO, 2003) for stations from Honduras, Costa Rica and Panama.
direction: negative
scope: climate
variable: precipitation
variable detail: Seasonal, annual
variable group: EffectiveMoisture
variable group direction: negative
variable group original: P_amount

scope: climate

scope: climate

basis: Sub-annual cyclic isotopic signatures of several permil represent the annual cycle of local rainfall and relative humidity. Additional data from a plantation tree of known age from ENSO-sensitive northwestern coastal Peru suggests that the 1997–8 ENSO warm phase event was recorded as an 8‰ anomaly in the δ18O of α-cellulose.
