Drought is a research program of the Australian Centre of Excellence for Climate Extremes led by Andy Pittman and Michael Roderick.
Will the frequency, intensity or duration of Australian droughts increase in the future?
By delivering a program of research, backed by large scale scientific activity that integrates land, atmosphere and ocean scientists, is possible to understand the behavior of droughts to inform decision makers on strategies to increase national resilience and assess potential mitigation strategies.
This program will use the Millennium Drought as a test case because we do not know its causes, why it lasted so long or why it was so intense.
It is known climate models do not simulate drought of an equivalent spatial and temporal extent. This program seeks to understand the mechanisms linked to drought and improve the ACCESS model so that these processes are properly simulated. The aim of this Research Program is therefore: to determine the processes controlling the frequency, intensity and duration of drought in Australia in the past, present and future.
This program is divided in four related projects:
- Project 3.1: Large-scale climate processes that influence drought
- Project 3.2: Quantifying millennial-scale drought using observations and models: are recent changes unusual and are future projections unprecedented?
- Project 3.3: The role of land-atmosphere feedbacks during drought onset, persistence and termination
- Project 3.4: Vegetation and hydrology interactions with drought
