A multivariate event occurs when several hazards affect the same region at the same time. Each of the fires occurring during the Australian Black Summer bushfires qualifies as a multivariate compound event as it was caused by the simultaneous occurrence of several hazards including high temperature, low humidity, dry conditions leading up to the event, and strong winds in the same region. The ARC Centre of Excellence for Climate Extremes has recently published research on the occurrence of multivariate compound events across the globe.
