SAM and regional rainfall in IPCC AR4 models: Can anthropogenic forcing account for southwest Western Australian winter rainfall reduction?

How To Account For Groundwater Exchanges In Rainfall-Runoff Models?

Rainfall-runoff models sometimes have to deal with hydrological systems for which the water balance cannot be closed without taking into account the relation between surface and groundwater. In this study we intend to clarify in which kind of situations surface hydrologists should worry about these relations. We also conduct a preliminary study about how underground exchanges could be integrate...

Classifying rainfall districts: a south Western Australian study

The largest State in Australia, Western Australia, covers an area of approximately 2.5 million square kilometres, extending from latitude 14oS to 35oS and from longitude 113oE to 129oE. The climate of Western Australia is influenced by its large size and latitudinal position. In the north of the State the climate is tropical and dominated by the Australian Monsoon, the south predominantly Medit...

SST phases and Australian rainfall

Long-term variations in winter rainfall of southwest Australia and the African monsoon

The rainfall in southwest Western Australia (SWWA) mostly falls in May to September, and predominantly in June, July and August (JJA). Records show that, prior to the 1960s, this area had the most reliable rainfall in the country, but in the late 1960s a decrease of approximately 20 per cent (from approximately 3.8 mm/day to 3 mm/day for JJA) occurred in the longterm mean (IOCI 2002), which per...

Rainfall and its seasonality over the Amazon in the 21st century as assessed by the coupled models for the IPCC AR4

[1] The global climate models for the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4) predict very different changes of rainfall over the Amazon under the SRES A1B scenario for global climate change. Five of the eleven models predict an increase of annual rainfall, three models predict a decrease of rainfall, and the other three models predict no significant change...
