Figure: The multimodel median changes of precipitation indices of R20mm (top), RX5day (middle), and CDD (bottom) by the end of 21st century (2081–2100) under the SSP245 (left) and SSP585 (right) scenarios with respect to the reference period 1986–2005. Here, shading is only shown for regions where at least 90% of the models agree on the direction of the change. CMIP6 models exhibit a general improvement in simulation of climate extremes and their trend patterns compared to observations. The model spread among CMIP6 models tends to be much smaller than that among their predecessors, particularly for regions in high northern latitudes. In response to further warming in the future, the TXx and TNn show a general increase in this century, but the increase in TNn is much greater than that in TXx. Additionally, precipitation indices of R20mm and RX5day are projected to significantly increase across lands, while increase in CDD is limited to the Southern Hemisphere (Figure). These changes are generally more pronounced in CMIP6 than CMIP5 simulations, but the model spreads are still comparable between CMIPs, which still needs further investigation. [ABSTRACT FROM AUTHOR]
