Do CMIP6 Climate Models Simulate Global or Regional Compound Events Skillfully?

Compound events have the potential to cause high socioeconomic and environmental losses. We examine ability of sixth phase Coupled Model Intercomparison Project (CMIP6) models capture two bivariate compound events: co-occurrence heavy rain strong wind, heat waves meteorological drought. evaluate over North America, Europe, Eurasia, Australia using observations reanalysis data set spanning 1980–2014. Some CMIP6 return periods both Eurasia surprisingly well but perform less Australia. For this poor performance was particularly clear in northern which suggests limits simulating tropical extratropical cyclones, local convection, mesoscale convective systems. did not find higher model resolution improved any region. Overall, our results show some can be used events, Eurasia.
