Figure 3: Comparison between the Taiwan tree-ring δ18O (red) and the precipitation δ18O (blue) in the adjacent western Pacific obtained from the Global Network of Isotopes in Precipitation.

From: Recent enhancement of central Pacific El Niño variability relative to last eight centuries

(a) r=0.42 with Bangkok precipitation δ18O (n=40, P<0.0001). (b) r=0.57 with Hong Kong (n=35, P<0.0001). These plots suggest that the Taiwan tree-ring δ18O reflects large-scale regional hydrological signals. (c) NIÑO4 sea-surface temperature anomaly time series (http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/ensostuff/ensoyears.shtml). The horizontal line denotes 0 °C value. SSTA, SST anomaly.
