The objective of the project is to use a combination of station-based measurements and reanalyses (e.g. BARRA, ERA-5) to create a climatology of precipitable water for Australia. After creating the dataset, the student will also analyse trends and variability.
The aim of this student project is to investigate the effect of bias correction and downscaling methods on hydrological projections for Australia.
The associations between rainfall variability, ENSO and temperature appeared to be stationary early in the record, but there was a hint that there was some evidence of a shift in the late 1990s. Has that shift continued? Alternatively, have the rainfall variance characteristics returned to what was observed earlier in the record? This project will use the latest observed datasets to explore these questions.
