Summary
Compound events (CEs) can pose significant threats to societies, economies and ecosystems around the world, especially when amplified by anthropogenic climate change (ACC). There is therefore a strong need for skillful, reliable and actionable predictions of how CEs are expected to change in the next decades, to support governments and stakeholders in implementing robust adaptation strategies. In this project, we will develop a method to improve near-term projections of CEs at the global scale, taking into account their response to both climate variability and long-term warming, and develop a sound physical mechanism understanding of their meteorological drivers. First, we will constrain climate projections with decadal climate predictions, from the Coupled Model Intercomparison Project Phase 6, with a novel method to reduce the uncertainty and increase accuracy of ACC predictions up to 30 years. Then, we will apply an innovative method grounded in dynamical systems theory for quantifying CEs and link them to physical extremes in the global regions where the prediction of events shows high skill. We will specifically focus on temperature-(low) precipitation as related to summer heatwaves and precipitation-wind as a proxy for storms. The analysis will elucidate what drives CEs in the context of global warming and climate variability, to what extent they can be predicted on decadal to multi-decadal time scales, and how their frequency, intensity and persistence is expected to change in the future. We will furthermore explore the atmospheric drivers of the CEs, to elucidate specific physical mechanisms at the origin of the events. The outcomes of the project will be significant for the scientific community, since they will improve the understanding of how CEs respond to ACC and climate variability, and relevant for governments and stakeholders aiming to reduce losses from high-impact weather events, benefiting societies and economies around the world.
