Fig. 7: Rainfall is related to SPCZ temperature.

Monthly correlation (r) of HadlSST1 (1870-1984) with summer (DJFMA) rainfall at Jeannie River (blue star) in preceding September (a), preceding November (b), and concurrent February (c). Positive SST correlation with Queensland rainfall builds in the preceding Aug–Dec and moves toward the coast through the austral spring. Positive rainfall correlation with SST breaks down in austral summer and fall. North Queensland rainfall is negatively correlated with central tropical Pacific SST, i.e., the region is wetter in more ‘La-Niña’-like years. Green hexagon is New Caledonia, green triangles are Fiji, Tonga, and Rarotonga (from west to east). Figure made using KNMI Climate Explorer66. www.climexp.knmi.nl.
