Australian researchers in the ARC Centre of Excellence for Climate Extremes have made major contributions to the 2021 IPCC Working Group 1 report, through the authorship of the report, review and the many scientific papers cited in the report.
Errors in identifying the fire scar - the portion of a long-lasting bushfire that is actively burning or smouldering, are the largest errors in forecasting emissions from these events. This project will develop and analyse fire progression tracking using data from the 2019 - 2020 bushfire season.
The most advanced and comprehensive analysis of climate sensitivity yet undertaken has revealed with more confidence than ever before how sensitive the Earth’s climate is to carbon dioxide. The range has been reduced from 1.5°C-4.5°C down to 2.3°C-4.5°C.
The scientific community is moving away from “beauty contest” thinking where models are accepted or rejected on the basis of how well they simulate particular aspects of the present or past, toward a smarter approach that seeks to understand and exploit how present and future predictions are related as well as how different models are related.
Convective vertical velocity is crucial for understanding cloud-precipitation systems, yet direct observations of convective vertical velocity are currently limited. In this project, you will estimate convective cloud top vertical velocity using Himawari-8/9 satellite data available at 2 km resolution every 10 minutes over Northern Australia since July 2015.
In this project, we seek to utilise 40 years of observations of water vapour profiles from the global radiosonde network to improve our process level understanding of water vapour mixing. The applicant is expected to know the basics of atmospheric physics and statistics. Some knowledge of data processing tools will be an advantage.
Convective parameterizations are widely believed to be essential for realistic simulations of the atmosphere, but are crude in today's weather and climate models. CLEX researchers, report on what happens when a number of these models are run with these schemes simply turned off.
