摘要：
The relationship between hydroclimate and El Nino/Southern Oscillation (ENSO) has been used in forecasting rainfall and streamflow. This paper presents a lag correlation analysis using rainfall and streamflow data from 284 Australian catchments that show that the ENSO-hydroclimate relationship is a lot stronger when the Inter-decadal Pacific Oscillation (IPO) phase is negative compared to when it is positive. The remarkable contrast in the hydroclimate-ENSO relationship between the two IPO phases suggests that the IPO should be considered in developing forecast models, particularly for long lead-times.
