What is an MJO and how does it affect the weather?
The MJO was first described in 1971 but a field project held over the west equatorial Pacific during 1992-93 raised awareness of the MJO as a coherent phenomenon, possibly useful for weekly predictions of tropical precipitation and extratropical weather patterns.

the Madden-Julian Oscillation (MJO; Madden and Julian, 1972), the global frictional torque and the global mountain torque were combined to construct four distinct phases of a global synoptic dynamic model (GSDM) of the atmosphere.
Abstract: NOAA Physical Sciences Laboratory
Jan 28, 2025 · The Madden Julian Oscillation (MJO) is a dominant mode of tropical variability and a key driver of sub-seasonal to seasonal climate predictability in mid-latitudes through tropical-extratropical teleconnections.

A new Madden–Julian oscillation (MJO) index is developed from a combined empirical orthogonal function (EOF) analysis of meridionally averaged 200-hPa velocity potential (VP200), 200-hPa zonal wind (U200), and 850-hPa zonal wind (U850).
