South Pacific Convergence Zone forecast May to July 2013

The ensemble of global climate models for rainfall that are used in METPI show an area of higher than normal rainfall associated with the SPCZ position. The green line indicates the average SPCZ position for the forecast period based on the average of 8 climate models. The white vertical bars and 'whiskers' indicate the one and two standard deviations between the model projections of the SPCZ position every 5 degrees of longitude. 

For May-July 2013, the SPCZ is expected to sit south of normal for the time of year. Uncertainty in the SPCZ position forecast is greatest to the east of the Dateline.
