Dec 12, 2005 · A subgroup was organized to focus on MJO operational prediction and was tasked to develop a MJO forecast metric for comparison of dynamical models from operational global …
Madden–Julian oscillation - Wikipedia
In the Pacific, strong MJO activity is often observed 6 to 12 months prior to the onset of an El Niño episode, but is virtually absent during the maxima of some El Niño episodes, while MJO …
What is the MJO, and why do we care? - NOAA Climate.gov
Dec 31, 2014 · The MJO consists of two parts, or phases: one is the enhanced rainfall (or convective) phase and the other is the suppressed rainfall phase. Strong MJO activity often …
MJO: Madden-Julian Oscillation Diagnostics | Climate Data Guide
Sep 9, 2022 · "The Madden–Julian oscillation (MJO) is the largest element of the intraseasonal (30–90 days) variability in the tropical atmosphere. It is a large-scale coupling between …
What is the Madden-Julian Oscillation? - Met Office
There is evidence that the MJO influences the El Nino Southern Oscillation (ENSO) cycle. It does not cause El Nino or La Nina, but it can contribute to the speed of development and intensity of...

The Madden-Julian Oscillation, often referred to as the MJO, is a mode of sub-seasonal atmospheric variability that influences the location and strength of tropical precipitation.
Madden-Julian Oscillation (MJO) - NASA Earthdata
Dec 17, 2025 · The Madden-Julian Oscillation (MJO) is known as the dominant mode of tropical intraseasonal variability and has an important role in the coupled-atmosphere system.
