a Australia map including locations of major east coast cities of Brisbane (B) and Sydney (S) and rainfall regions most strongly correlated to LDsss17,25, incorporating key agricultural and urban water supply catchments; nMDB (blue) = northern Murray Darling Basin, ESB (orange) = eastern seaboard, and Burnett/Mary River catchment (green). b NDJF seasonal regional rainfall distributions over 1979/80 to 2015/16 for LDsss upper (LDsss > 0.192 logCl, n = 13) and lower (LDsss < 0.014 logCl, n = 12) tercile years (>66%, <33%). Wilcoxon signed-rank test used to determine the significance (95%) of mean regional rainfall between LDsss upper/lower tercile years over 1979/80–2015/16. Refer to Supplementary Fig. S1a for LDsss timeseries split by tercile groups. c NDJF climatology over 1979/80–2015/16 (ERA-Interim58) of daily total precipitation and surface winds (10 m) over study domain, including location of Brisbane (B) and Law Dome (LD). d NDJF composite conditions of daily total precipitation and surface wind (10 m) anomalies during LDsss lower tercile years. e As e during LDsss upper tercile years.
