Rainfall is the key hydroclimatic variable that plays a vital role in the development of regional water management policies. Assessment of observed rainfall behaviour and its spatial and temporal variations are therefore important for climate change adaptation measures. This study assessed trends and step changes in observed annual and seasonal rainfalls across the South Australian region. More than 100 years of high‐quality r...

The intention of this study was to identify a suitable Generalized Linear Model ( GLM ) for modelling multi‐site daily rainfall in the Onkaparinga catchment in South Australia and to examine the suitability of the model for downscaling of General Circulation Model ( GCM ) rainfall projections. A GLM was applied and multi‐site daily rainfall was downscaled using National Centers for Environmental Prediction/National Center for...

Rainfall events and inter‐event spell properties were analysed in this study using observed daily rainfall sequences for Adelaide and Melbourne in Australia. First and higher order transitional probabilities of dry and wet days were also estimated. Various statistical moments of spells were estimated and compared between Adelaide and Melbourne. Six theoretical distributions were fitted to the dry and wet spells. These were geo...
