Figure 1: ENSO influence on tropical hydroclimate.
From: Western Pacific hydroclimate linked to global climate variability over the past two millennia
Field correlation map of annual rainfall and east equatorial Pacific sea surface temperatures. Correlation coefficients (r) were calculated between GPCP v2.2 precipitation (at each 1° × 1° grid point) and HadISST1 NINO3.4 SSTs (1979–2010). The coloured dots show the location of our study site and other paleoclimate records mentioned in the text. Yellow indicates relatively dry conditions during the Medieval Climate Anomaly5,6,9,44,46,48 (950–1250 CE), whereas cyan/purple indicates relatively wet conditions7,8/intense precipitation events10,47.
