Possible influences from mean state change under greenhouse warming based on CMIP5. a Composites of JJASON mean rainfall anomalies (mm per month) for events that are similar to 2018–2019 sequences in the Control climate, i.e., 1900–1999. b The same as a, but for the Future climate, i.e., 2000–2099. Dotted areas indicate where the difference between a and b is significant at the 95% confidence level based on a Student t-test. c Projected changes in Australia JJASON rainfall between 2000–2099 and 1900–1999. d The same as c, but in surface temperature (°C). Results are based on 17 CMIP5 models that produce reasonable ENSO diversity (Cai et al. 2018). Dotted area in c and d indicate where the difference between two period is significant above the 95% confidence level based on a Student t-test
