Abstract

Storms, wind and hail do a lot of damage to Australians and their property. The 1999 Sydney hailstorm, for instance, cost A$1.7 billion in insured losses. That makes it the biggest single insurance loss in Australian history; in today’s money it would have cost more than A$4 billion.

More recently, one of the most severe storms in decades caused a statewide blackout in South Australia in September. The intense low-pressure system featured seven tornadoes that tore down three major transmission lines.

Our understanding of wind and hail depends on the type of storm that generates them – and this is where it gets complicated. Thunderstorms can generate not just heavy rainfall but also high winds, lightning and hail, albeit in very localised areas. Large-scale storms such as tropical cyclones are a different phenomenon altogether, bringing not just destructive winds, but also storm surges and soaking rains, often over wide areas.

This complexity makes storms difficult to study, because limited research resources are spread across the many different storm types and their associated hazards.

To help address these issues, we collated and reviewed the latest knowledge and understanding of storms in Australia, covering the current scientific literature on the assessment, causes, observed trends and future projected changes of storm hazards, with a specific focus on severe wind and hail. We found that progress has been made in many areas, but also that much remains to be done.
