Multidecadal variability of rainfall and streamflow: Eastern Australia

摘要: [1] This study investigates the influence of El Nino–Southern Oscillation (ENSO) and Interdecadal Pacific (IPO) on rainfall streamflow regimes eastern Australia. An analysis historical data for Queensland (QLD), New South Wales (NSW), Victoria (VIC) reveals strong relationships between these indices seasonal totals. Rainfall in NSW QLD are shown to be significantly enhanced during La Nina phase ENSO, with impacts diminishing as one moves south into VIC. In addition, shows that a multidecadal timescale negative IPO is associated “wetter” conditions than positive phase. Importantly, already demonstrated even further magnified events occur This result particular importance ENSO VIC appears weak; however, results indicate some useful predictability can achieved
