Cyclone Debbie: Sonification Background Report
This report examines the formation and impacts of Cyclone Debbie, the most powerful storm to make landfall in Queensland.
Making landfall on the 28 March 2017, Debbie caused widespread devastation and flooding, resulting in the second highest damage bill of any extreme weather event to hit Australia. Her high wind speeds and rainfall wrecked havoc from North Queensland, right through to Northern New South Wales. Given the widespread impacts, this storm was an obvious choice to be the first Australian cyclone sonified.
It also explores the process of data sonification, a process of taking data collected every 6 hours from Debbie’s formation and creating an audio track representing the storm's latitude, longitude, circularity and central air pressure.
Key findings of the report include:
- Cyclone Debbie was the first cyclone since the 2014-15 season to reach severe status (Category 3 (AUS) or more).
- Cyclone Debbie was the most powerful storm to make landfall in Queensland (QLD) since Cyclone Yasi in 2011.
