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.
Weekly cycles of atmospheric parameters over Australia and the quantification of human influences on climate. Many human activities are organised on a seven-day cycle. The consequences of this might be expected to appear in the average variations of meteorological parameters across the week. This research will investigate these intra-week variations at many locations across Australia and will provide a critical insight into the human impact on climate.

Summary
Improving the seasonal prediction of Australian rainfall extremes. This project aims to investigate the predictability of Australian extreme rainfall using the latest Bureau of Meteorology seasonal prediction system and new re-analyses and climate models. Extreme rainfall events in Australia are often associated with loss of life and damage to infrastructure and the environment, but some impacts can be mitigated with improved forecasting. This project will analyse influences of climate change an ....Improving the seasonal prediction of Australian rainfall extremes. This project aims to investigate the predictability of Australian extreme rainfall using the latest Bureau of Meteorology seasonal prediction system and new re-analyses and climate models. Extreme rainfall events in Australia are often associated with loss of life and damage to infrastructure and the environment, but some impacts can be mitigated with improved forecasting. This project will analyse influences of climate change and climate variability on seasonal-scale predictability of extreme rainfall. This will increase our understanding of the processes behind extreme rainfall events and where predictability arises from, and this would result in improvements in forecasting.Read moreRead less
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. Due to the availability of new Australian research infrastructure, large steps forw ....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. 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
Tropical convection and its contribution to climate variability. This research will provide the necessary data to test and improve the representation of tropical convective clouds in weather forecast and climate simulation models. This will lead to more robust estimates of future climate change, and improved prediction of precipitation in the Australian tropics. This project will also provide training to undergraduate and postgraduate students in using modern computer models; such models will be ....Tropical convection and its contribution to climate variability. This research will provide the necessary data to test and improve the representation of tropical convective clouds in weather forecast and climate simulation models. This will lead to more robust estimates of future climate change, and improved prediction of precipitation in the Australian tropics. This project will also provide training to undergraduate and postgraduate students in using modern computer models; such models will be a key component of weather forecasting in the future.Read moreRead less
Precipitation Events over Tasmania and their Response to Weather Modification. The ongoing cloud-seeding work undertaken by Hydro Tasmania will be investigated through a combination of fieldwork and numerical simulations.

The ongoing cloud-seeding work undertaken by Hydro Tasmania will be investigated through a combination of fieldwork and numerical simulations. New instrumentation and advanced numerical models will allow this research to provide a new understanding of the precipitation events over Tasmania and their response to cloud seeding. This research will also explore the interaction between the background aerosol/pollution level and the precipitation. Given the relatively pure nature of the air over Tasmania, this research will be of international interest. This research will also be of direct interest to Hydro Tasmania as insight gained into the precipitation events will allow us to optimise their cloud-seeding operation.Read moreRead less
Coupling tropical cyclone and climate physics with ocean waves. It is argued that without accounting for the wave effects directly, the physics of large-scale air-sea interactions is inaccurate and incomplete. The project will introduce explicit coupling of large-scale atmospheric and oceanic phenomena with the physics of surface waves which should lead to improved predictions of tropical cyclones and climate.
The dynamics and predictability of fire weather over southern Australia. As illustrated by the recent Victorian bushfires, Australia has one of the most severe fire climates in the world. Fires play a major role in modifying our landscape, affecting native flora and fauna, and damaging infrastructure and property. Effective fire fighting and fire management relies heavily on the prediction of fire weather and the impact of atmospheric conditions on fire behaviour. This project investigates some ....The dynamics and predictability of fire weather over southern Australia.

Fires play a major role in modifying our landscape, affecting native flora and fauna, and damaging infrastructure and property. Effective fire fighting and fire management relies heavily on the prediction of fire weather and the impact of atmospheric conditions on fire behaviour. This project investigates some of the key processes that cause local enhancements in fire weather in regions of complex terrain like southern Australia.Read moreRead less
Wave-Induced Upper-Ocean Mixing. The wave-induced mixing is of principal importance for air-sea interaction models since heat capacity of 2-3m of the ocean water is equal to the capacity of the entire atmosphere. This project will study and implement such mixing, including the newly described physical phenomenon of wave-induced turbulence, into a variety of models. As a result, wave models and global climate models will be coupled. It is believed that such coupling will enhance our ability to pr ....Wave-Induced Upper-Ocean Mixing.

As a result, wave models and global climate models will be coupled. It is believed that such coupling will enhance our ability to predict the impact of global climate change. As part of the project, predictions of changes to the global wave climate will be developed. Such predictions are important to a nation such as Australia where significant population and economic assets are located close to the coast.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.
