Tropical climate change, the Hadley and Walker Circulations, and Australian climate

热带气候系统，特别是翻转环流和季风，在最近几十年发生了变化，预计下个世纪还会发生变化。然而，事实证明，对这些问题的全面理解是难以捉摸的。该项目将采用一套深刻的热带环流诊断方法，这些诊断方法是根据最新的高质量数据和建模结果计算得出的，以分离出起作用的关键物理机制。这项研究意义重大，因为热带环流决定了地球表面大部分地区的降水和温度，尤其是澳大利亚。这些变化的物理基础将有助于形成对“湿热带”和“干燥地区”未来气候的展望。

Tropical climate systems, especially the overturning circulations and monsoons, have undergone change in recent decades and are expected to do so over the next century. However, a full understanding of these has proved elusive. The project will employ a suite of insightful diagnostics of these tropical circulations calculated from the latest, high-quality data and the results of modelling to isolate the key physical mechanisms at work. The research is significant in that tropical circulations determine the precipitation and temperature over large parts of the Earth’s surface, and particularly Australia. The physical underpinning of the changes will assist in forming outlooks for future climate for the ‘wet tropics’ and the ‘dry zones’.
