Projections of Australian low pressure systems in downscaled CMIP6 models Open
Low pressure systems are associated with a number of climate hazards in Australia, including heavy rainfall, strong winds and coastal erosion. Here, we use a new ensemble of 40 CMIP6 (Sixth Coupled Model Intercomparison Project)-based regi…

Disentangling the uncertainties in regional projections for Australia Open
Understanding, quantifying and visualising projected ranges of future regional climate change is important for informing robust climate change impact assessments. Here, we examine projections of Australian sub-continental regionally averag…

Springtime rainfall changes in Australia related to projected changes in large-scale modes of variability Open
In this study, we estimate changes in Australian springtime (September–November) rainfall associated with projected changes in large-scale climate modes of variability. Using 33 climate models from the sixth phase of the Coupled Model Inte…

Global representation of extratropical cyclone precipitation and future trends in CMIP6 models Open
We use a cyclone‐tracking algorithm to study precipitation produced by extratropical cyclones in reanalysis data and climate models. In the Southern Hemisphere, we find strong zonal asymmetries in extratropical cyclone precipitation, with …

Recent trends in extratropical lows and their rainfall over Australia Open
Low pressure systems are an important source of rainfall in southern Australia, particularly deep lows that extend from the surface to at least 500 hPa. This paper uses multiple reanalyses to assess long-term trends in lows over the period…

Anthropogenic warming reduces the likelihood of drought-breaking extreme rainfall events in southeast Australia Open
Future climate change is projected to increase the frequency and severity of droughts in many drought-prone regions of the world. However, coarsely-resolved and sometimes opposing rainfall changes across global climate models, and a lack o…

MODELLED AND OBSERVED IMPACT OF THE APRIL 2021 SOUTHERN OCEAN STORM Open
Wind-wave extreme events are a major driver of coastal erosion (Lowe et al., 2010). As such, accurate estimates of metocean extremes are crucial to implement efficient and resilient coastal defense strategies. Global wave reanalysis datase…

The Role of Weather System Changes and Catchment Characteristics in the Rainfall‐Runoff Relationship Shift in Victoria, Australia Open
Many Victorian catchments experienced a rainfall‐runoff relationship (RRR) shift during the Millennium Drought (1997–2009). Less annual streamflow was generated from annual rainfall during the drought than would have been expected for the …

Atmospheric trends explained by changes in frequency of short-term circulation patterns Open
The circulation of the atmosphere is subject to natural and anthropogenic forcings that alter the energy balance of the climate system. In each hemisphere the zonally averaged atmospheric circulation can be represented by a single overturn…

Projections of synoptic anticyclones for the twenty-first century Open
Synoptic anticyclones are a common feature of subtropical and midlatitude climate and are associated with descending air and clear conditions, while associated anticyclonic circulation anomalies can contribute to temperature extremes. When…
