The impact of the diurnal cycle on the propagation of Madden‐Julian Oscillation convection across the Maritime Continent

Journal of Advances in Modeling Earth Systems, 2016
Influences of the diurnal cycle on the propagation of the Madden‐Julian Oscillation (MJO) convection across the Maritime Continent (MC) are examined using cloud‐permitting regional model simulations and observations.

Evaluation of Global Storm‐Resolving Models in DYAMOND‐Winter: Radiation, Precipitation, Water Vapor, and Convective Organization

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract We present a comprehensive evaluation of 13 global storm‐resolving models participating in the DYnamics of the Atmospheric general circulation Modeled On Non‐hydrostatic Domains (DYAMOND) Winter intercomparison project, focusing on their ability to simulate key atmospheric fields, such as precipitation rate, outgoing longwave radiation, and ...

Lagged Response of MJO Convection and Precipitation to Solar Ultraviolet Variations on Intraseasonal Time Scales

Geophysical Research Letters
Composite analyses of NOAA satellite‐based outgoing longwave radiation data and ERA5 reanalysis data for nearly six solar maximum periods support the existence of a response of tropical convection and precipitation to short‐term (∼27‐day) solar ...

Precipitation Characteristics and Thermodynamic‐Convection Coupling in Global Kilometer‐Scale Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract We compare three global kilometer‐scale models (ICON, IFS and NICAM) to clarify the advantages and challenges of high‐resolution global weather and climate modeling, using different approaches to represent convection, from fully parameterized to fully explicit.

Observed connection between the Madden–Julian oscillation and the upper tropospheric biennial oscillation

Environmental Research Letters
It has been found that the quasi-biennial oscillation (QBO) in the stratosphere have an important impact on the Madden Julian oscillation (MJO). In this study, we show that there is an obvious biennial oscillation in the tropical upper troposphere, which

An Idealized Two‐Dimensional Atmospheric Model of the Quasi‐Biennial Oscillation and Wave‐Mean Flow Interactions in the Equatorial Channel

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract The quasi‐biennial oscillation (QBO) is a fundamental mode of atmospheric variability and a textbook example of wave‐mean flow interactions. While its general theory has been established about 50 years ago by the seminal works of Holton, Lindzen and Plumb (HLP), it remains an unsettled problem of geophysical fluid dynamics and a challenge for ...

Accurate Column Moist Static Energy Budget in Climate Models. Part 1: Conservation Equation Formulation, Methodology, and Primary Results Demonstrated Using GISS ModelE3

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Column‐integrated moist static energy (MSE) budgets underpin theories of tropical convection and circulation, yet in reanalyses and climate models the budget rarely closes; residuals routinely match the leading terms and mask physical insights.

Potential Strengthening of the Madden–Julian Oscillation Modulation of Tropical Cyclogenesis

Atmosphere
A typical Madden–Julian Oscillation (MJO) generates a large region of enhanced rainfall over the equatorial Indian Ocean that moves slowly eastward into the western Pacific.

Global‐scale convective aggregation: Implications for the Madden‐Julian Oscillation

, 2015
Previous work has shown that convection will self‐organize in cloud‐system‐resolving model simulations of radiative‐convective equilibrium, and it has been suggested that the convective envelope of the Madden‐Julian oscillation (MJO) may be organized by ...
