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.
How does orography enhance precipitation in Australian wintertime storms? 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 an ....How does orography enhance precipitation in Australian wintertime storms? 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

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.
