QBO deepens MJO convection. [PDF]
Nat Commun, 2023 AbstractThe underlying mechanism that couples the Quasi-Biennial Oscillation (QBO) and the Madden-Julian oscillation (MJO) has remained elusive, challenging our understanding of both phenomena. A popular hypothesis about the QBO-MJO connection is that the vertical extent of MJO convection is strongly modulated by the QBO.

Journal of Geophysical Research D: Atmospheres, 2018 AbstractActivities of the Madden‐Julian Oscillation (MJO) in boreal winter has recently been found to be stronger in easterly phases of the stratospheric quasi‐biennial oscillation (QBO) than its westerly phases. This QBO‐MJO connection was investigated in this study using a method that identifies individual MJO events by tracking their eastward ...

Phase-dependent modulation of the MJO during cross-equatorial northerly surges (CENS) [PDF]
Scientific ReportsThis study investigates phase-dependent associations between Cross-Equatorial Northerly Surges (CENS) and Madden-Julian Oscillation (MJO) precipitation and circulation patterns using 84 years (1940–2023).

The Impact of MJO-C and MJO-B Upon Sea Surface Temperature and Rainfall in Indonesia
Omni-Akuatika, 2023 Madden Julian Oscillation (MJO) based on its propagation through the maritime continent can be divided into two types, namely MJO-C (Crossing) and MJO-B (Blocked) as evidenced by the spatial diagram of Hovmöller OLR anomaly. This study aimed to determine

Combined effect of the QBO and ENSO on the MJO
Atmospheric and Oceanic Science Letters, 2019 This study investigates the combined effect of the El Niño–Southern Oscillation (ENSO) and stratospheric quasi-biennial oscillation (QBO) on the Madden Julian Oscillation (MJO).

MJO simulation in CMIP5 climate models: MJO skill metrics and process-oriented diagnosis [PDF]
Climate Dynamics, 2017 The Madden-Julian Oscillation (MJO) simulation diagnostics developed by MJO Working Group and the process-oriented MJO simulation diagnostics developed by MJO Task Force are applied to 37 Coupled Model Intercomparison Project phase 5 (CMIP5) models in order to assess model skill in representing amplitude, period, and coherent eastward propagation of ...

Underestimated MJO variability in CMIP6 models [PDF]
Geophysical Research Letters, 2021 AbstractThe Madden‐Julian Oscillation (MJO) is the leading mode of intraseasonal climate variability, having profound impacts on a wide range of weather and climate phenomena. Here, we use a wavelet‐based spectral Principal Component Analysis (wsPCA) to evaluate the skill of 20 state‐of‐the‐art CMIP6 models in capturing the magnitude and dynamics of ...

Bulletin of the American Meteorological Society, 2022 ABSTRACT Objectively identifying a phenomenon from observation is often difficult. This essay reflects upon this problem from a philosophical perspective by taking the Madden–Julian oscillation (MJO) as an example. I argue that it can be considered as a problem of Gestalt.
