Waliser, D. E., K. M. Lau, W. Stern, and C. Jones, 2003: Potential predictability of the Madden-Julian oscillation. Bulletin of the American Meteorological Society, 84(1), 33-50.

Abstract: Ensembles of twin-predictability experiments suggest that successful dynamical forecasts of the Madden-Julian oscillation may offer one avenue for bridging the gap between medium to long-range weather forecasting and short-term climate prediction.
