Ground-based observations and model simulations show substantial increases in extreme events including rainfall events, droughts, wildfires, hot spells and heatwaves. The first step toward improving our societal resilience is to identify the new patterns of climate extremes and natural hazards. This requires a better understanding of tempo-spatial characteristics of natural hazards and also the interactions between different hazards in a changing climate.  A combination of climate events (e.g., high temperatures and high humidity, or low precipitation and high temperatures) may cause a significant impact on the ecosystem and society, although individual events involved may not be severe extremes themselves – a notion known as compound event (e.g., extreme rain over burned areas, combined ocean and terrestrial flooding). Numerous studies have focused on how different types of extremes have changed or might change in the future. However, very few studies have investigated the changing risk of compound and cascading events. This presentation focuses on three different types of  compound and cascading events including drought-heatwaves, sea level rise-terrestrial flooding, and meteorological-anthropogenic drought. We present different methodological frameworks and perspectives for detecting, modeling and risk assessment of compound and cascading events.

Amir AghaKouchak is a Professor of Civil and Environmental Engineering at the University of AghaKouchak PhotoCalifornia, Irvine.  His research focuses on natural hazards and climate extremes and crosses the boundaries between hydrology, climatology, remote sensing.  Website: http://amir.eng.uci.edu/
