MJO forecast archive

Follow the links below to access archive forecast data. Each link is a page with a grid of maps for that month. Each row corresponds to a particular day. Within each row, from left to right, is the analysis map (i.e., the actual state of the MJO on that day) followed by the forecast maps for that day at lead times of 5, 10, 15, 20, 25, 30, 35 and 40 days. Hence, for any given day, a qualitative assessment can be made on the skill and consistency of the forecasts valid on that day, for each lead time. Typically, the forecasts are skillful (i.e., the forecast maps looks similar to the analysis map) out to lead times of about 20-25 days. Beyond 25 days, the forecasts tend to lose skill.

Note that the maps extend into the future, as forecasts were made today for up to 40 days lead time. Clearly these times do not yet have an analysis map.
