Guidelines for Studying Diverse Types of Compound Weather and Climate Events
Abstract Compound weather and climate events are combinations of climate drivers and/or hazards that contribute to societal or environmental risk. Studying compound events often requires a multidisciplinary approach combining domain knowledge of the underlying processes with, for example, statistica...
