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.

热带太平洋导致澳大利亚降雨量和极端气候逐年发生显着变化。然而，由于数值气候模型的系统偏差，热带气候预测受到严重限制。该项目旨在利用新技术并利用国际合作，通过对关键的海气相互作用和海洋混合过程的新理解，转变我们模拟热带太平洋气候的能力。预期成果包括在澳大利亚气候模型中更好地代表热带气候，并提高季节到年际的预测能力。这些改进的预测将使社区有更多时间为干旱、热浪和丛林大火等极端事件做好准备。
