Figure 2. Same as Fig.1, but for CMIP5: Hist (grey), RCP2.6 (green), RCP4.5 (blue), and RCP8.5 (red).
To illustrate the spreads and medians of the projected climatological changes in extremes over Australian regions in detail, boxplots for SSP5-8.5&RCP8.5 and SSP1-2.6&RCP2.6 are shown in Figs. 3 and 4, and Figs. S2 and S3 for SSP3-7.0 and SSP2-4.5&RCP4.5. Over the regions, the spreads of the indices in SSPs and RCPs tend to be larger with higher emission pathways and over time, among which some regions such as NA and TA commonly span relatively wider ranges. Compared to RCP8.5, the spreads in SSP5-8.5 are usually larger, especially over the period 2071-2100. As for the multi-model medians, most indices display larger warming trends over TA and lower warming over southern Australian regions (e.g., SSA and SWA); while for other indices (e.g., TXx, TNx and TN10p), there are relatively similar warming levels across the 10 regions. Relative to RCPs, the warming levels for some indices (e.g., TXx, TNn, and WSDI) tends to be higher under the SSPs; in contrast, the relative magnitudes of some indices between RCPs and SSPs, such as TXn and TNx (e.g., Fig. 3b, c and Fig. S3b, c), differ among the regions and the levels of radiative forcing.
