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 …

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 activity is …

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 dissects the planet …

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 atmospheric …

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 MJO is a large tropical convective-circulation system that forms every one to three months (intraseasonal) over the Indian Ocean to West Pacific Ocean warm pool region.

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.

The MJO is best defined over the oceanic warm pool, which extends from the Indian Ocean to the central Pacific and where complex variations of precipitation occur from day to day.

Madden-Julian Oscillation (MJO) The MJO consists of large-scale regions of enhanced and suppressed convection, and associated circulation anomalies in the tropics that propagate eastward, mainly over …

Dec 20, 2023 · The Madden–Julian Oscillation (MJO) is a dominant source of subseasonal atmospheric variability in the tropics and significantly impacts global weather and climate predictability.
