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.
