Correlated Climate Extremes: Drivers, Mechanisms, and Risks

Session ID#: 80112

Session Description:
Climate extremes that occur near-simultaneously in time and/or space can pose amplified risks for societies, exemplified by the mortality and agricultural losses from summer 2018’s co-occurring heat and flood events across the Northern Hemisphere. Such spatiotemporally correlated climate extremes belong to three categories: (i) compound extremes (multiple variables, same time and place); (ii) concurrent extremes (same time, multiple places); (iii) sequential or persistent extremes (multiple times, same place). Their complex nature and severe impacts require joint efforts from a broad range of scientific communities to understand and mitigate their hazards, especially in a changing climate. Correlational framing provides a basis for linking hazard-relevant research across disciplines and scales, from meteorology to decadal variability. We invite contributions that assess the risk of correlated climate extremes through evaluation of their dynamical, hydrological, and/or land-surface mechanisms, as well as innovative modeling or statistics that improve their detection, attribution, or future projections.
