Linking Southern Ocean water masses and Australian rainfall variability
Rainfall in Australia and indices developed to monitor climate variability exhibit distinct pattern of multi-decadal variability. It is possible that physical mechanisms operating in the Southern Ocean are a driver of this behaviour. In particular, the formation of water masses within defined geogra...

Rainfall in Australia and indices developed to monitor climate variability exhibit distinct pattern of multi-decadal variability.
