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

Revisiting the physics of clouds. Revisiting the physics of clouds: This fellowship project aims to bring new rigour to climate modelling by improving our understanding of key phenomena like clouds and storms. Earth’s climate has taken a number of turns in the recent and geologic past that so far cannot be reproduced in models. Clouds and atmospheric turbulence are also a problem for weather and climate prediction, the conceptual understanding of which now has evident flaws.

Revisiting the physics of clouds: This fellowship project aims to bring new rigour to climate modelling by improving our understanding of key phenomena like clouds and storms. Earth’s climate has taken a number of turns in the recent and geologic past that so far cannot be reproduced in models. Clouds and atmospheric turbulence are also a problem for weather and climate prediction, the conceptual understanding of which now has evident flaws. The hypothesis of this project is that these two problems are strongly linked, and that this link may be exploited to solve problems across disciplines. This project aims to systematically re-evaluate our conceptual understanding of cloud physics, and investigate how this affects our understanding of climate phenomena in Earth’s past and future.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

This project aims to employ targeted field observations, numerical simulations and new satellite capabilities to identify the dynamical and microphysical mechanisms that enhance and redistribute precipitation across the alpine regions of south eastern Australia and Tasmania. These observations will be used to evaluate operational numerical weather simulations specifically focusing on quantitative precipitation forecasts and estimates. The observations will also be used to extend known biases in the national gridded precipitation analysis that are a result of the complex mountain terrain. This identification of the physical processes that enhance and redistribute precipitation over the alpine regions across south east Australia and Tasmania will lead to better precipitation estimates and forecasts and better water management.Read moreRead less
