MJO as a Gestalt [PDF]

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.

Preliminary evaluation of MJO simulation in GAMIL3 (Grid-point atmospheric model of IAP LASG)

Atmospheric and Oceanic Science Letters, 2020
This study evaluates the performance of the Grid-point Atmospheric Model of IAP LASG, version 3 (GAMIL3), in simulating the Madden–Julian Oscillation (MJO), based on the CMIP6 (phase 6 of the Coupled Model Intercomparison Project) AMIP (Atmospheric Model

Cracking the MJO nut [PDF]

Geophysical Research Letters, 2013
AbstractThe Madden‐Julian oscillation poses great challenges to our understanding and prediction of tropical convection and the large‐scale circulation. Several internationally coordinated activities were recently formed to meet the challenges from the perspectives of numerical simulations, prediction, diagnostics, and virtual and actual field ...

Impacts of the Tropical Pacific–Indian Ocean Associated Mode on Madden–Julian Oscillation over the Maritime Continent in Boreal Winter

Atmosphere, 2020
Based on the observation and reanalysis data, the relationship between the Madden–Julian Oscillation (MJO) over the Maritime Continent (MC) and the tropical Pacific–Indian Ocean associated mode was analyzed.

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 ...

The MJO‐SSW Teleconnection: Interaction Between MJO‐Forced Waves and the Midlatitude Jet [PDF]

Geophysical Research Letters, 2018
AbstractThe Madden‐Julian Oscillation (MJO) was shown to affect both present‐day sudden stratospheric warming (SSW) events in the Arctic and their future frequency under global warming scenarios, with implications to the Arctic Oscillation and midlatitude extreme weather.

Influence of the Madden–Julian Oscillation on the Arctic Oscillation Prediction in S2S Operational Models

Frontiers in Earth Science, 2021
The connections between the Madden–Julian Oscillation (MJO) and the Arctic Oscillation (AO) are examined in both observations and model forecasts. In the observations, the time-lag composites are carried out for AO indices and anomalies of 1,000-hPa ...

Stratospheric ozone and quasi-biennial oscillation (QBO) interaction with the tropical troposphere on intraseasonal and interannual timescales: a normal-mode perspective [PDF]

Earth System Dynamics, 2021
The Madden–Julian oscillation (MJO) is the main controller of the weather in the tropics on intraseasonal timescales, and recent research provides evidence that the quasi-biennial oscillation (QBO) influences the MJO interannual variability.

Interannual variability of the frequency of MJO phases and its association with two types of ENSO

Scientific Reports, 2021
In this study, we reexamine the effect of two types of El Niño Southern Oscillation (ENSO) modes on Madden Julian Oscillation (MJO) activity in terms of the frequency of MJO phases.

Dynamical Madden–Julian Oscillation forecasts using an ensemble subseasonal-to-seasonal forecast system of the IAP-CAS model [PDF]

Geoscientific Model Development
The Madden–Julian Oscillation (MJO) is a crucial predictability source on a subseasonal-to-seasonal (S2S) timescale. Therefore, the models participating in the World Weather Research Programme and the World Climate Research Programme (WWRP/WCRP) S2S ...
