Fig. 2: NDJF daily total precipitation and surface (10 m) wind anomaly (data: ERA-Interim58) for the nine SOM nodes from ref. 33 over 1979/80 to 2017/18.

SOM nodes 1 to 9 are labelled (a–i). SOM composite anomalies calculated from the NDJF climatology (Fig. 1c). SOM3 (SOM7) supports lower (upper) LDsss composite conditions (Fig. 1d, e), reflecting reduced (strengthened) westerly winds near Law Dome (LD) coastline and dry (wet) eastern Australia (B = Brisbane). Note the precipitation scale is non-linear.
