Historical MJO Indices
The figures below show the ten MJO indices, ordered from 1 to 10 and displayed from top to bottom, for selected winter seasons. Note that the pentad data used in the MJO composites are labeled as blue dots, and the MJO indices are standardized by the standard deviation in the ENSO-neutral and weak ENSO winters (November-April) during 1979-2000.
