Abstract
Based on idealized experiments (preindustrial control experiment (PI) and 1% yr−1 increase (1%CO2) in atmospheric CO2) from 10 general circulation models produced under the Coupled Model Intercomparison Project Phase 5 and using the fraction of attributable risk, we examine the CO2 effects on extreme precipitation at the subdaily and daily scales. We find that the increased CO2 concentration substantially increases the odds of the occurrence of subdaily precipitation extremes compared to the daily scale in most areas of the world, with the exception of some regions in the subtropics, likely in relation to the subsidence of the Hadley Cell. These results point to the large role that atmospheric CO2 plays in extreme precipitation under an idealized framework.
Key Points
Increased CO2 substantially increases the odds of the occurrence of subdaily precipitation extremes more so than at the daily scale
Differences in influence of CO2 between subdaily and daily precipitation extremes are stronger in tropics and extratropics than subtropics
This study points to the large role that atmospheric CO2 plays in extreme precipitation under an idealized framework
