Wave-Induced Upper-Ocean Mixing. The wave-induced mixing is of principal importance for air-sea interaction models since heat capacity of 2-3m of the ocean water is equal to the capacity of the entire atmosphere. This project will study and implement such mixing, including the newly described physical phenomenon of wave-induced turbulence, into a variety of models. As a result, wave models and global climate models will be coupled. It is believed that such coupling will enhance our ability to pr ....Wave-Induced Upper-Ocean Mixing.

This project will study and implement such mixing, including the newly described physical phenomenon of wave-induced turbulence, into a variety of models. As a result, wave models and global climate models will be coupled. It is believed that such coupling will enhance our ability to predict the impact of global climate change. As part of the project, predictions of changes to the global wave climate will be developed. Such predictions are important to a nation such as Australia where significant population and economic assets are located close to the coast.Read moreRead less
Contribution of surf zone wind stress to storm surge inundation. In the present era of climate change, storm surge forecasting is becoming an increasingly important part of disaster management planning. The responsible state and national agencies require accurate forecasting tools in order to best safeguard communities and plan infrastructure. Storm surges result from low pressure atmospheric conditions and wind forces on the ocean. However, the wind forces on the surf zone are unknown, with the ....Contribution of surf zone wind stress to storm surge inundation. In the present era of climate change, storm surge forecasting is becoming an increasingly important part of disaster management planning. The responsible state and national agencies require accurate forecasting tools in order to best safeguard communities and plan infrastructure. Storm surges result from low pressure atmospheric conditions and wind forces on the ocean. However, the wind forces on the surf zone are unknown, with the result that inaccurate warnings are issued to communities. This project will lead to significant improvements in forecast accuracy by providing this missing data and by developing new models for the surf zone wind forcing. Read moreRead less
Oceanic Conditions within Extreme Tropical Cyclones. Australia's tropical and subtropical areas include major infrastructure projects such as the North West shelf oil and gas projects, major mining operations, export ports, natural environments such as the Great Barrier Reef and major tourism industries. All these industries are crucially impacted by extreme tropical cyclones. Despite the importance of these systems, our present understanding of tropical cyclones is incomplete. This project will ....Oceanic Conditions within Extreme Tropical Cyclones. Australia's tropical and subtropical areas include major infrastructure projects such as the North West shelf oil and gas projects, major mining operations, export ports, natural environments such as the Great Barrier Reef and major tourism industries. All these industries are crucially impacted by extreme tropical cyclones. Despite the importance of these systems, our present understanding of tropical cyclones is incomplete. This project will significantly enhance our ability to carry out accurate engineering design of critical offshore infrastructure, as well as marine forecasts in such environments. As such, the project will have major scientific, economic and social benefits for Australia.Read moreRead less
