Until recently, we have considered extreme events as rare, which means there have been few data available to make assessments regarding changes in their frequency, intensity, and after-effects. Indeed, confidence in observed changes in extremes depends on the quality and quantity of data and the availability of studies analysing these data, which vary across regions and for different extremes. The rarer the event the more difficult it is to identify long-term changes or how to respond after the event.
In this webinar, our panel explores the application of extreme event data for improved understanding from three perspectives – national, local and recovery.
1. Extreme Events – the big picture. Dr Dan Metcalfe, Oceans and Atmosphere Director, CSIRO
Dr Metcalfe is co-authoring the 2021 State of Environment (SoE) chapter on Extreme Events. Dan will discuss the data and case studies underpinning the chapter with respect to cyclones and storms; flooding; storm-surges and coastal inundation; heatwaves; bushfires; and hail and snow.
2. Rapid assessment of erosion risk after wildfires. Dr Xihua Yang, Principal Research Scientist, NSW Dept of Planning, Industry and Environment.
Dr Yang’s innovative use of the digital soil maps together with climate and satellite data, is being adopted globally to develop a spatial and temporal analysis on hillslope erosion after an extreme event. In Australia it has helped improve recovery activities after the 2019–2020 bushfires.
3. Measuring a fire. Dr Tim Wardlaw, Honorary Research Associate, University of Tasmania
In 2019, the first fire event in the Tasmania’s Tall Eucalypt Forest since 1898 swept through nearly 64,000 ha of land in Tasmania. Thanks to the longevity and diversity of TERN’s measurements, Dr Wardlaw can provide unprecedented detail of the event, using a diverse suite of before-, during- and after-fire measurements.
