A comprehensive understanding of Australian heat waves: past, present and future.

点击翻译按钮获取中文摘要

The frequency and duration of Australian heat waves is increasing. Existing theories include natural and human influences, however the relative roles of specific heat wave drivers are undefined. Using an ensemble of contemporary climate models, this project will determine the individual and combined roles of anthropogenic activities, natural forcings and internal variability that shape heat wave manifestation. Using the ability of models to simulate the appropriate mechanistic connections, plausible future projections of heat waves will be ascertained. This will be the first comprehensive analysis of changes in heat waves, providing essential resources for the adaptation, mitigation and preparedness towards future events.
