Precipitation in shallow convection over the Southern Ocean. This project aims to quantify the amount of precipitation over the Southern Ocean and identify the key dynamical and microphysical processes that lead to its development. Large uncertainties exist in the frequency and intensity of precipitation, which limits the ability to model the coupled Southern Ocean climate system. Observations from the RV Investigator, an Australian marine research vessel, have revealed heavy precipitation event ....Precipitation in shallow convection over the Southern Ocean. This project aims to quantify the amount of precipitation over the Southern Ocean and identify the key dynamical and microphysical processes that lead to its development. Large uncertainties exist in the frequency and intensity of precipitation, which limits the ability to model the coupled Southern Ocean climate system. Observations from the RV Investigator, an Australian marine research vessel, have revealed heavy precipitation events within the shallow convection commonly found between fronts that have not been captured by either satellite observations or numerical models. This project will improve weather forecasts, including precipitation, and climate projections over the Southern Ocean and the adjoining Antarctic and the southern part of Australia.Read moreRead less

Summary
The cause of the poleward shift of Earth's storm tracks and jet streams. Why do global climate models shift the atmospheric storm tracks and jet streams poleward in simulations of future climate? This project will determine the underlying causes of the most important circulation change that is projected to occur with increasing greenhouse gases, and will allow much more accurate regional climate projections.
Improving the avoidance and prediction of turbulence from thunderstorms. One of the most critical weather-related safety issues for aviation is atmospheric turbulence caused by thunderstorms. Thunderstorm-generated turbulence is responsible for frequent serious injuries and significant costs to airlines that are ultimately passed on to passengers. Using extensive new data, case studies and state-of-the-art simulations, this project aims to improve our understanding of the dynamics and behaviour ....Improving the avoidance and prediction of turbulence from thunderstorms. One of the most critical weather-related safety issues for aviation is atmospheric turbulence caused by thunderstorms. Thunderstorm-generated turbulence is responsible for frequent serious injuries and significant costs to airlines that are ultimately passed on to passengers. Using extensive new data, case studies and state-of-the-art simulations, this project aims to improve our understanding of the dynamics and behaviour of thunderstorm-generated turbulence and its representation in weather forecast models. Expected outcomes of this project include the development of new methods to avoid and predict turbulence for use by the aviation industry. This research should provide significant benefits, such as safer and more efficient air travel.Read moreRead less
Precipitation in wintertime storms across southeast Australia, Tasmania and the Southern Ocean. The pristine conditions and strong wind-shear over the Southern Ocean affect the formation of precipitation in clouds over the region, which is vital to the water supply of southeastern Australia and Tasmania. This project will evaluate and improve the ability to simulate this precipitation, which will lead to better water resource management.
The Southern Ocean boundary layer: winds, turbulence, sea spray and clouds. Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment.

Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment. Due to the availability of new Australian research infrastructure, large steps forward are now possible with modest investment. This project will conduct and combine observations from the recently acquired marine vessel, RV Investigator, and the collocated airborne and surface observations to understand the structure and evolution of the unique, pristine SO boundary layer and to evaluate satellites and climate models.Read moreRead less

Summary
Mobile weather radar system for advanced environmental monitoring and modelling. High spatial and temporal resolution weather radar data on wind and precipitation will translate to significant environmental model advances. Australian researchers will undertake model validation studies on precipitation, dust storm, and flood prediction under a wider range of environmental conditions and in greater detail than currently possible.
Numerical prediction of bushfire behaviour and bushfire weather. Bushfires are a threat to Australia’s population and infrastructure, but there are many aspects of fire behaviour that are poorly understood. This project will examine how bushfires interact with the atmosphere and how these interactions influence fire spread. This research will underpin the development of new systems for fire weather prediction.
