Compound events often span multiple hazard types and locations and cause complex impacts to communities, ecosystems, and economies. It is therefore critical to connect scientific disciplines at an international level for furthering our collective understanding of these events.
The aim of the compound events working group is to create and sustain an international community with an interest in weather/climate compound events, including their characteristics, risks, and impacts. Our focus is mostly on the physical science of high-impact compound events, but we encourage contributions and insights from all fields.
Meet the team!
Carlo De Michele
Carlo De Michele is Professor of Hydrology and Water Resources Engineering at the Department of Civil and Environmental Engineering, Politecnico di Milano, where he has served since 2019. He was previously Associate Professor (2007–2019), and Assistant Professor (1999–2006) at the same institution. His research focuses on the assessment and modeling of hydrological extremes and compound climate-related events, scaling and complexity in hydrology, climate change impacts on the hydrologic cycle, reliability and resilience of water engineering systems. He is Member of the International Association of Hydrological Sciences (IAHS), the European Geosciences Union (EGU), and the American Geophysical Union (AGU). He has authored more than 190 peer-reviewed journal articles and the book Extremes in Nature: An Approach Using Copulas (Springer). As a didactic initiative, He organizes the “Como Training School on Compound Climate-related Events”, held every 2–3 years.
Colin Raymond
Colin Raymond is an Assistant Research Scientist at the University of California, Los Angeles. His research centers on the interaction of heat and hydrological extremes, particularly how they can compound across physical and human systems to amplify risk. In addition to quantitative analysis,
he is enthusiastic about advancing projects and methods that produce accessible and actionable weather/climate information.
