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

近几十年来，热带气候系统，特别是翻转环流和季风，发生了变化，预计在下个世纪还会发生变化。然而，对这些问题的充分理解已被证明是难以实现的。该项目将采用一套对这些热带环流的深刻诊断，这些热带环流是根据最新的高质量数据和建模结果计算出来的，以隔离工作中的关键物理机制。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，特别是澳大利亚的降水和温度。这些变化的物理基础将有助于形成对“湿热带”和“干燥带”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’.
