What is it about?

The declining rainfall over SWA is a major problem for WA. In this paper, the rainfall patterns are classified using a clustering algorithm (e.g. coastal, inland, etc) and analyzed them to know which ones are likely to change in the future. Also, the changes in the intensity or in the frequency of the rainfall patterns are studied.

Why is it important?

Future planning of hydrological resources needs to consider the declining rainfall over the region. This paper quantifies the changes in the intensity and frequency of GCMs rainfall prediction. Importantly, several CMIP5 models are used to provide uncertainty in the projected trends.


This work is focused on details of the projected changes in rainfall over SWA. It gives an idea of changing the intensity and frequency of different weather systems over the region in high and low carbon emissions scenarios with associated uncertainty in the projection.
