This research was supported in part by the Managing Climate Variability Program of Land and Water Australia, through the multi-institution collaborative project QPI62. H. M. initiated this project while employed by the Queensland Department of Primary Industries and Fisheries, Australia. The NCEP–NCAR reanalysis were obtained from the Physical Sciences Division of NOAA/ESRL, and we thank NOAA as a whole for their measurement and provision of the OLR data. Thanks to Robert Fawcett for his part in producing the gridded rainfall dataset and to Fiona Lo for her assistance in retrieving it. We also thank James Risbey, Nicolas Fauchereau, Guomin Wang, Graham Mills, Aline de Maia, Benjamin Pohl, Ian Jolliffe, and Adrian Matthews for their comments.
