Summary
New models and estimation methods in nonlinear panel data econometrics. This project will develop new econometric models and methods for capturing dynamic and complex relationships within economic and social systems. The outcomes of this project are expected to improve policy making process concerning climate change, economy and financial markets, through providing accurate estimates of relationships of interest.
Trending time series models with non- and semi-parametric methods. The outcomes of this project will not only complement but also enhance the existing strengths and reputation of Australian researchers in the field of econometrics. The outcomes are also expected to help improve model building and forecasting from better models in climatology, economics, environmetrics and financial econometrics.
Dissipation and relaxation in statistical mechanics. This project studies the mathematical conditions for relaxation either to equilibrium or to steady states, which is important in predicting behaviour in diverse fields including climate modelling, materials science, nanotechnology and biology. Early career researchers will be involved in the project, gaining valuable skills in theory and simulation.
Non- and Semi-Parametric Panel Data Econometrics: Theory and Applications. This project proposes to tackle several very important and difficult issues in modelling general climatological, economic and financial panel data that involve possible trending components. This project seeks to establish some general asymptotic theory for model estimation and specification technologies that are suited to such general nonlinear panel data that may be stochastically non-stationary and endogenous.

This project seeks to establish some general asymptotic theory for model estimation and specification technologies that are suited to such general nonlinear panel data that may be stochastically non-stationary and endogenous. The research outcomes of this project are expected to be applicable in evaluating and improving empirical model building and forecasting from better models in climatology, economics and finance with possible endogeneity and nonlinearity and non-stationarity.Read moreRead less
Improved theory and practice in econometric modelling of nonlinear spatial time series. Modern Australia faces many challenges in economic and global climate changes, which require advanced statistical technologies in modeling and forecasting of econometric spatial time series data. This project will provide flexible models and methods that enable practitioners to more accurately measure and manage economic and climatic risks.
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.

Summary
Entrainment and interface dynamics of turbulent flows. Patches of turbulent flow such as in clouds, volcanic or bushfire plumes grow with time because they draw or entrain non-turbulent fluid through their boundaries. The quantity of fluid entrained, and why it entrains this amount, is poorly understood. This is a major bottleneck in our ability to predict how these natural phenomena evolve in time. This project aims to employ idealised laboratory models of these natural phenomena, and utilise h ....Entrainment and interface dynamics of turbulent flows. Patches of turbulent flow such as in clouds, volcanic or bushfire plumes grow with time because they draw or entrain non-turbulent fluid through their boundaries. The quantity of fluid entrained, and why it entrains this amount, is poorly understood. This is a major bottleneck in our ability to predict how these natural phenomena evolve in time. This project aims to employ idealised laboratory models of these natural phenomena, and utilise high quality measurement techniques and theoretical tools to quantify and understand the physical basis of the entrainment mechanism. The project aims to create better climate models and more accurate predictions of natural disasters associated with bushfires and volcanos.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
The dynamics of subtropical anticyclones and the connection to drought, heatwaves and bushfires in southern Australia. The aim of the project is to understand the dynamics of anticyclones (high pressure systems) in the region of southern Australia. The study of anticyclones in the region is important because of their very strong connection to rainfall in the winter, and heatwaves and bushfires in the summer, and because so little work has been done on understanding what is the defining feature o ....The dynamics of subtropical anticyclones and the connection to drought, heatwaves and bushfires in southern Australia. The aim of the project is to understand the dynamics of anticyclones (high pressure systems) in the region of southern Australia. The study of anticyclones in the region is important because of their very strong connection to rainfall in the winter, and heatwaves and bushfires in the summer, and because so little work has been done on understanding what is the defining feature of the climate of southern Australia. Understanding what controls the location and strength of these features will go a long way to explaining how the climate of southern Australia will change in a warmer world.Read moreRead less

Summary
Assimilation of ocean wave interactions with sea ice into climate models. Contemporary climate models do not accurately portray ocean or atmosphere interactions where the open ocean meets the expanses of floating sea ice within the polar regions, as they lack a component to determine the size of ice floes. This project will tackle the omission directly, developing from modelling advances made in recent years.
