High impact compound events in Australia
Almost all catastrophic events are the consequence of multiple drivers acting together.
What is a multivariate compound event in weather and climate?
A multivariate event occurs when several hazards affect the same region at the same time.
What is a spatially compounding event in weather and climate?
A spatially compounding event occurs when several impacts occur at the same time but at different locations.
What is a temporally compounding event in weather and climate?
A temporally compounding event occurs when a series of hazards affects the same region, exacerbating the impact of any of the individual events.
What is a pre-conditioned compound event in weather and climate?
A preconditioned compound event occurs when the impact of a hazard is exacerbated by pre-existing conditions.

The difference in results between the high-skill and low-skill CMIP6 models highlights an urgent need to examine why some models work well and some don’t, and, ultimately, improve those with weaknesses.
