This project will examine whether ACCESS-S1 model can replicate the observed seasonal pattern of extreme rainfall timing in Australia, and the relationship with large-scale drivers.
CLEX researchers and colleagues find Australia's infrastructure would be unable to deal with past flood events and thus is very likely to be unable to mitigate future flooding under climate change.
The Extreme Rainfall team took on some key observational challenges for precipitation research and then used some of this data to test our models. There was also a raft of individual achievements to add a little light in this difficult time.
Sometimes there is so much to look back on that it can be difficult to know where to begin and that is definitely the case for the past three months of a very active Extreme Rainfall research program.
In this paper, CLEX researchers considered the steady-state response of the atmosphere to an imposed large-scale flow. They found that under these steady-state conditions, humidity increases with the precipitation rate, while the lapse rate (rate of decrease of temperature with height) increases.
The past four months have produced a sequence of impressive papers that should significantly improve the modelling of precipitation and our capacity to better understand how it may change in the future.
This student project will determine the probability of a drought being terminated by an extreme precipitation event to assess the risk of drought-induced flooding. For this the student will assess observations, reanalysis data and results from a large climate model ensemble.
Large areas of northern Queensland experienced extreme rainfall and severe flooding in late January and February 2019. This briefing note examines the impacts and some of the likely causes of the event.
CLEX researchers with the Bureau of Meteorology have created a new 20-year-long regularly updated precipitation dataset for Australia using 50 radar sites. This will allow researchers to examine the climatology of extreme events, follow cloud processes, estimate hail size, determine cloud top height and much more.
The past four months have seen Extreme Rainfall researchers win a slew of awards and produce some important foundational research on storms, hybrid cyclones, and some unexpected influences on extreme rainfall events.
