Abstract Recent studies have shown that individual Madden–Julian oscillation (MJO) events can be categorized into four types based on their propagation characteristics: standing, jumping, slow-propagating, and fast-propagating MJOs. While their structures and impacts are well documented in observations, their representation in state-of-the-art climate ...

Abstract The Madden–Julian oscillation (MJO) is a large-scale eastward-moving system that dominates tropical subseasonal perturbations with far-reaching impacts on global weather–climate. For nearly a half century since its discovery, there has not been a consensus on the most fundamental dynamics of the MJO, despite intensive studies with a number of ...

Diverse MJO Genesis and Predictability
Bulletin of the American Meteorological Society, 2023Abstract The Madden–Julian oscillation (MJO) is the dominant intraseasonal wave phenomenon influencing extreme weather and climate worldwide. Realistic simulations and accurate predictions of MJO genesis are the cornerstones for successfully monitoring, forecasting, and managing meteorological disasters 3–4 weeks in advance.

AbstractIn this study, the authors seek large-scale signals that may distinguish MJO from non-MJO convective events before they start over the Indian Ocean. Three such signals were found. Low-level easterly anomalies extend from the surface to the midtroposphere and move from the western to eastern Indian Ocean.

The aim of the present study is to investigate the impact of Madden-Julian Oscillation on the climate of European area, and in particular the correlation of the eight MJO phases with specific climate parameters, both for winter and summer. For this purpose, NCEP/NCAR reanalysis data were used, covering the period 1976-2015. The reanalysis represent the

The Experimental MJO Prediction Project
Bulletin of the American Meteorological Society, 2006Weather prediction is typically concerned with lead times of hours to days, while seasonal-to-interannual climate prediction is concerned with lead times of months to seasons. Recently, there has been growing interest in 'subseasonal' forecasts---those that have lead times on the order of weeks (e.g., Schubert et al. 2002; Waliser et al.

ENSO regulation of MJO teleconnection
Climate Dynamics, 2010The extratropical teleconnections associated with Madden–Julian Oscillation (MJO) are shown to have an action center in the North Pacific where the pressure anomalies have opposite polarities between the Phase 3 (convective Indian Ocean) and Phase 7 (convective western Pacific) of the MJO. The teleconnection in the same phase of MJO may induce opposite

QBO‐MJO Connection in CMIP5 Models
Journal of Geophysical Research: Atmospheres, 2020AbstractRecent studies have shown that the quasi‐biennial oscillation (QBO) affects the boreal winter Madden‐Julian oscillation (MJO), its teleconnection, and even its subseasonal prediction skill. Despite its widespread influences, the QBO‐MJO connection has rarely been examined with a climate model. Here, we demonstrate that the QBO‐MJO connection is

Multiplicative MJO Forcing of ENSO
Journal of Climate, 2012Abstract The Madden–Julian oscillation (MJO) is parameterized to study the role of the feedback it receives from sea surface temperature (SST) in its influence on El Niño–Southern Oscillation (ENSO). The parameterization describes MJO surface westerlies in terms of a few basic parameters that include amplitude, zonal propagation extent ...

Multiscale theories for the MJO
2011In the equatorial troposphere, the Madden–Julian Oscillation (MJO) is a planetaryscale wave envelope of complex multiscale convection (see Figure 17.1 for a schematic illustration). It begins as a standing wave in the Indian Ocean and propagates eastward across the western Pacific Ocean at a speed of 5 m/s.
