Large-scale climate variability and change
The large-scale climate variability and change group deals with all aspects of climate or weather variability that is longer than a week and involves regional scales larger than 1000km. We address questions such as: How does a tropical cyclone in the Indian Ocean lead to heat waves in Melbourne or how does changes in the ocean temperatures in the tropical Atlantic affect our rainfall patterns in Australia or what is causing a decade of drought. This also involves understanding and simulating the global climate response to anthropogenic climate change, and understanding the drivers of the recent hiatus in global surface warming. We deal with a wide range of methods from theoretical considerations, to data analysis of observations and simulations to modelling of the climate over the full range of complexities and scales.
