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
Testing a new explanation of cloud feedback on global climate. A new analysis suggests that the sensitivity of global climate to greenhouse gases is largely controlled by the upward transport of water vapour in the lower troposphere, but the analysis did not examine clouds, which must be involved for the mechanism to be valid. The aim of the proposed project is to determine whether variations in cloud implied by this new explanation are supported by observations and process models. If the explan ....Testing a new explanation of cloud feedback on global climate. A new analysis suggests that the sensitivity of global climate to greenhouse gases is largely controlled by the upward transport of water vapour in the lower troposphere, but the analysis did not examine clouds, which must be involved for the mechanism to be valid. The aim of the proposed project is to determine whether variations in cloud implied by this new explanation are supported by observations and process models. If the explanation is confirmed, then for the first time in over 30 years of intense research it will be possible to determine the long-term severity of global warming by examining the present-day atmosphere. The expected outcome of this research is to clarify how and why low clouds change in altered climates.Read moreRead less
Cloudiness over the Southern Ocean: reducing a key knowledge gap and source of climate model uncertainty. Southern Ocean clouds are key ingredients of the global climate system and yet are only poorly understood and poorly represented in climate models. Through the use of advanced observational analysis techniques this research will provide a deep understanding of key Southern Ocean cloud regimes and improve their representation in models.
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
Cloud-climate interaction over the Great Barrier Reef and Southwest Pacific. This project aims to investigate cloud-climate interactions of the Southwest Pacific trade wind region from the regional scale to local forcing over the Great Barrier Reef.

This project aims to investigate cloud-climate interactions of the Southwest Pacific trade wind region from the regional scale to local forcing over the Great Barrier Reef. The project expects to generate new knowledge in the nature and variability of the trade wind clouds, including their impact on the surface radiative budget, ocean temperatures and coral bleaching events. Potential changes of these clouds due to global warming and ensuing impacts on the environment will be studied. Expected outcomes include better modelling of the Great Barrier Reef environment and improved estimates of low-cloud feedback. This should provide significant benefits in developing warning systems for bleaching events, and regional land and water management. Read moreRead less
GBR as a significant source of climatically relevant aerosol particles. Every cloud drop is formed from a microscopic aerosol particle, known as a cloud condensation nuclei (CCN).

Every cloud drop is formed from a microscopic aerosol particle, known as a cloud condensation nuclei (CCN). In unpolluted environments the CCN particles originate from biogenic sources. Determining the magnitude and driving factors of biogenic aerosol production in different ecosystems is crucial to the development and improvement of climate models. This project aims to determine the mechanisms of new particle production from one of the biggest ecosystems in Australia, the Great Barrier Reef. It is expected that the project will establish whether marine aerosol along the Queensland coast is coral-derived and show that this aerosol can affect the CCN concentration and therefore cloud formation and the hydrological cycle.Read moreRead less
