Project Overview

This pilot project was part of the Climate Change Science and Knowledge Program funded by the Department for Environment and Water. The project was led by Assoc Prof Mark Thyer and research team members Dr David McInerney, Prof Seth Westra and Assoc Prof Michael Leonard.

The study involved analyzing rainfall data from monitoring stations and rainfall radar in the Adelaide metropolitan area. This analysis examined changes to high intensity rainfall (e.g. 99th percentile and 99.9th percentile of rainfall) for range of up to 3 durations that are practically relevant (e.g. 30 minutes to 90 minutes rainfall events). Analysis was conducted at 3 or more rainfall monitoring stations, with the stations selected according to the quality of data and their geographic suitability for the purposes of the study. 

Further analysis of rainfall radar data was conducted to examine changes in spatial maxima rainfall associated with storm intensity.

Progress Update and Key Findings

  • This study will deliver a short technical report, explaining methods and findings of the analysis, including section that outlines the practical implications and interpretation of the study findings.
