Physical mechanisms responsible for stable isotope ratios in precipitation over southeast Australia

该项目将确定确定澳大利亚东南部降水事件中稳定同位素含量（特别是18O和氘）的物理机制。其目的是以一种基于物理的方式，从同位素信号中推断出有关的天气和气候信息。这项研究将建立在对导致降水事件的时期的三维大气结构的综合分析，以及对大气-海洋耦合模式的创新使用上，该模式可以解释相关过程的大部分物理复杂性。

The project will identify the physical mechanisms which determine the stable isotopic content (specifically of 18O and deuterium) in southeast Australian precipitation events. An aim is to deduce, in a physically-based manner, relevant weather and climate information from the isotopic signals. The research will be founded on a comprehensive analysis of the three dimensional atmospheric structure in the period leading up to the precipitation events, and on the innovative use of a coupled atmosphere-ocean model which can account for much of the physical complexity of the relevant processes.
