Long‐Term Observations Reveal Non‐Negligible Temperature Contributions to Moist Static Energy During the MJO Transition From Suppressed to Active Phases

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The evolution of moist static energy (MSE) is widely used to understand the organization and propagation of the Madden‐Julian Oscillation (MJO). Past studies, largely based on reanalysis or short‐term observations, have highlighted humidity as the dominant driver of MJO evolution.

Modulation of Quasi‐Biennial Oscillation on Wintertime Variability of Intraseasonal 2‐m Temperature Over Northern Eurasia and Its Potential Impact on Subseasonal Prediction in China

Geophysical Research Letters
The mid‐high latitude intraseasonal oscillation (ISO) has remarkable impacts on the Northern Hemisphere. However, the interannual variance of the mid‐high latitude ISO and its underlying mechanism are rarely explored.

Meridional Dipole in Eddy Activity Along Peruvian Coast During Eastern Pacific El Niño Events

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale oceanic eddies (O $O$(100)km) play a key role in regulating climate by affecting the transport of heat and water mass properties. However, most climate models struggle to simulate these eddies due to coarse horizontal resolution. Using a 120‐year ultra‐high‐resolution simulation with 1/10° ${}^{\circ}$ horizontal ocean resolution ...

Multiscale Interactions between Local Short- and Long-Term Spatio-Temporal Mechanisms and Their Impact on California Wildfire Dynamics

Fire
California has experienced a surge in wildfires, prompting research into contributing factors, including weather and climate conditions. This study investigates the complex, multiscale interactions between large-scale climate patterns, such as the Boreal

Predictability Studies of the Intraseasonal Oscillation with the ECHAM5 GCM

Journal of the Atmospheric Sciences, 2005
Abstract Our ability to predict active and break periods of the Asian summer monsoon is intimately tied to our ability to predict the intraseasonal oscillation (ISO). The present study analyzes the upper limit of potential predictability of the northern summer ISO, as it is simulated by the ECHAM5 atmospheric general circulation model ...

A Simple Model of Convectively Coupled Equatorial Rossby Waves

Journal of Advances in Modeling Earth Systems, 2019
Intraseasonal oscillations affect the weather not just in the tropics but all around the globe. The convectively coupled equatorial Rossby wave is observed as the westward‐moving intraseasonal oscillation. The fundamental physics of its coupling is still

The Dynamics of Intraseasonal Atmospheric Angular Momentum Oscillations

Journal of the Atmospheric Sciences, 1997
Abstract The global and zonal atmospheric angular momentum (AAM) budget is computed from seven years of National Centers for Environmental Prediction data and a composite budget of intraseasonal (30–70 day) variations during northern winter is constructed.

Genesis of Intraseasonal Oscillations and Equatorial Waves

Journal of the Atmospheric Sciences, 2002
Abstract The particular role of evaporation–wind feedback, and as well cumulus convection and dissipation, in the formation of the Madden–Julian 30–60-day intraseasonal oscillation (MJO) and equatorially trapped waves, including Kelvin, equatorial Rossby, mixed Rossby–gravity, and eastward inertio-gravity waves, has been studied using a global two ...

The intraseasonal oscillation of pCO2 over the southeast coast of Vietnam in boreal summer

Environmental Research Communications
The intraseasonal oscillation (ISO) of the oceanic surface partial pressure of carbon dioxide ( p CO _2 ) is one of the primary subsequent effects of the monsoon-driven upwelling along the southeast coast of Vietnam (SCV) in boreal summer.
