Figure 4. Same as Fig. 3, but for SSP1-2.6 and RCP2.6.
Generally, the spatial patterns for the extremes in both CMIP6 and CMIP5
(Figs. 5 and 6; Figs. S4-S15 in the supplementary material) are similar
to previous studies (Alexander & Arblaster, 2017). In the highest
scenarios for CMIP6 and CMIP5, the extreme indices show a warmer
Australia than other pathways, especially in the end of this century.
For most indices (expect DTR in Fig. S6 and FD in Fig. S15), most models
(at least 75%) in both CMIP ensembles project significant changes in
extreme temperature indices over most regions of Australia, both in the
middle and the end of the century. However, there are different warming
patterns for some indices. For example, as shown in Fig. 5, the warming
pattern in TXx is relatively consistent among the regions, with the
highest warming over central Australia; while for TNn, Northern
Australia displays the most marked warming (Fig. 6).
