Summary
Mixing and air-sea coupling in the Pacific: Toward better El Nino forecasts. The Tropical Pacific drives significant year-to-year variability in Australian rainfall and climate extremes. However, tropical climate predictions are severely limited due to systematic biases in numerical climate models. Using new techniques and leveraging international collaborations, this project aims to transform our ability to simulate tropical Pacific climate through a new understanding of key air-sea interaction ....Mixing and air-sea coupling in the Pacific: Toward better El Nino forecasts. The Tropical Pacific drives significant year-to-year variability in Australian rainfall and climate extremes. However, tropical climate predictions are severely limited due to systematic biases in numerical climate models. Using new techniques and leveraging international collaborations, this project aims to transform our ability to simulate tropical Pacific climate through a new understanding of key air-sea interaction and ocean mixing processes. Expected outcomes include a better representation of tropical climate in the Australian climate model and improved seasonal to interannual predictive capability. These improved predictions will give communities more time to prepare for extreme events such as droughts, heatwaves and bushfires.Read moreRead less

Summary
Resolving ocean convection: new knowledge for a changing Antarctica. This project aims to improve our understanding of the role of convection on the Antarctic margins using a high-resolution, cutting-edge numerical approach. Convection is an important, but poorly understood oceanic process, which diverts heat away from the melting Antarctic ice shelves by transporting cold and salty water from the ocean surface to depth. The project outcomes will be new knowledge of the physics from novel numeri ....Resolving ocean convection: new knowledge for a changing Antarctica. This project aims to improve our understanding of the role of convection on the Antarctic margins using a high-resolution, cutting-edge numerical approach. Convection is an important, but poorly understood oceanic process, which diverts heat away from the melting Antarctic ice shelves by transporting cold and salty water from the ocean surface to depth. The project outcomes will be new knowledge of the physics from novel numerical models and theory, supported by insights from observations and model parameterisations. This timely research will improve prediction of sea level rise due to a changing Antarctica and enhance our ability to adapt to future climate scenarios, providing significant environmental and health benefits to Australians.Read moreRead less
Spanning ten billion scales from millimetre turbulence to global circulation. This project aims to explain the role of convection in the ocean. Convection is a key climate process yet it remains one of the most poorly understood mechanisms in the ocean and is crudely represented in climate models, leading to uncertainties in predictions of heat transport, climate change, polar ice loss and sea level rise. Using a unique turbulence-resolving approach and high-performance computing, the project wi ....Spanning ten billion scales from millimetre turbulence to global circulation. This project aims to explain the role of convection in the ocean. Convection is a key climate process yet it remains one of the most poorly understood mechanisms in the ocean and is crudely represented in climate models, leading to uncertainties in predictions of heat transport, climate change, polar ice loss and sea level rise. Using a unique turbulence-resolving approach and high-performance computing, the project will determine both the global role of buoyancy-driven convection in the broad ocean circulation and the local turbulence controls on melting rates of Antarctic ice-shelves. This will contribute to the formulation of better climate models and keep Australia at the forefront of oceanography and environmental fluid dynamics.Read moreRead less
