High-Frequency Orographically Forced Variability in a Single-Layer Model of the Martian Atmosphere [PDF]

, 1993
A shallow water model with realistic topography and idealized zonal wind forcing is used to investigate orographically forced modes in the Martian atmosphere.

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.

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 ...

Weakening and Shifting of the Saharan Shallow Meridional Circulation During Wet Years of the West African Monsoon

, 2017
The correlation between increased Sahel rainfall and reduced Saharan surface pressure is well established in observations and global climate models, and has been used to imply that increased Sahel rainfall is caused by a stronger shallow meridional ...

Network Divergence Reveals Predictable Pathways of Extreme Rainfall in Central India

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Extreme rainfall events over Central India have increased, reflecting intensified monsoon precipitation driven by factors like urbanization and land use change. With projections indicating further intensification and flood vulnerability, better prediction is critical.

Large‐Scale Drivers of Tropical Extreme Precipitation Events: The Example of French Overseas Territories

Geophysical Research Letters
Due to their severity and lack of predictability, understanding and forecasting extreme precipitation events (EPEs) is critical for disaster risk reduction.

Tropical and Subtropical South American Intraseasonal Variability: A Normal-Mode Approach

Meteorology
Instead of using the traditional space-time Fourier analysis of filtered specific atmospheric fields, a normal-mode decomposition method was used to analyze South American intraseasonal variability (ISV). Intraseasonal variability was examined separately

Observational evidence of the Kuroshio meander and its propagation in the East China Sea

Frontiers in Marine Science
Entering the East China Sea (ECS) through the east of Taiwan, the Kuroshio flows northeastward, with its pathway confined along the continental slope of the Okinawa Trough.

An intercomparison of intraseasonal variability in general circulation models and observations [PDF]

Low frequency oscillations appearing in three GCM seasonal cycle integrations are compared with the analyses of the European Center for Medium Range Weather Forecasting (ECMWF). All three models have the same resolution: 4 deg latitude by 5 deg longitude,
