A Laboratory Study of Ocean-Atmosphere Coupling in the Antarctic Circumpolar Wave

点击翻译按钮获取中文摘要

A laboratory model of the southern hemisphere mid-latitude ocean-atmosphere system will be used to investigate the dynamics of ocean-atmosphere coupling contributing to the Antarctic Circumpolar Wave (ACW). The ACW is a recently discovered multi-year climate oscillation which has considerable effect on Australian and New Zealand precipitation. This will be the first laboratory model to include global scale ocean-atmosphere processes, and will be used to test proposed mechanisms for the driving of the climate oscillation that is attributed to the ACW. The project will provide knowledge required for improved computational modelling and climate predictions.
