Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil

International Journal of Climatology, Volume 46, Issue 6, May 2026.
This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

Tropical mid-tropospheric CO_2 variability driven by the Madden–Julian oscillation [PDF]

, 2010
Carbon dioxide (CO_2) is the most important anthropogenic greenhouse gas in the present-day climate. Most of the community focuses on its long-term (decadal to centennial) behaviors that are relevant to climate change, but there are relatively few ...

A delay differential model of ENSO variability, Part 2: Phase locking, multiple solutions, and dynamics of extrema [PDF]

, 2010
We consider a highly idealized model for El Nino/Southern Oscillation (ENSO) variability, as introduced in an earlier paper. The model is governed by a delay differential equation for sea surface temperature in the Tropical Pacific, and it combines two ...

Improving Numerical Weather Forecasts of Rainfall Over Central Africa Using a Three‐Dimensional Variational Data Assimilation Technique and the Weather Research and Forecasting Model

Meteorological Applications, Volume 33, Issue 3, May/June 2026.
This study evaluates satellite radiance assimilation using the 3DVAR technique within WRFDA to improve rainfall forecasts over Central Africa. Results show modest error reduction and improved spatial organization of rainfall compared to CHIRPS, while atmospheric variables remain comparable with ERA5, highlighting the potential of data assimilation in ...

Influence of Western Pacific Madden–Julian Oscillation on New York City's Record‐Breaking Air Pollution in Early June 2023

Geophysical Research Letters
In early June 2023, New York City (NYC) and other cities in the northeastern US experienced a severe air pollution event. Although reports associated this hazardous pollution event with the smoke from Canadian wildfires, the factors triggering the ...

An Observational and Forecast Study of Super Typhoon Fung‐Wong in 2025 Over the South China Sea

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Super Typhoon Fung‐wong took an unusual track over the western North Pacific and the northeastern part of the South China Sea in the late typhoon season of 2025. This paper summarizes some integrated observations about this super typhoon, including aircraft, dropsonde and wind profiler data.

Global Impacts of the Madden–Julian Oscillation

Atmosphere-Ocean
Numerous studies have examined the regional impacts of the Madden-Julian Oscillation (MJO) on land surface air temperature and precipitation, but a global unified picture of the MJO impacts is still lacking. This study provides a global unified picture of the MJO impacts on land surface air temperature and precipitation for both the Northern Hemisphere

Assessment of the Madden‐Julian Oscillation in CMIP6 Models Based on Moisture Mode Theory

Geophysical Research Letters
The moist processes of the Madden‐Julian Oscillation (MJO) in the Coupled Model Intercomparison Project Phase 6 models are assessed using moisture mode theory‐based diagnostics over the Indian Ocean (10°S–10°N, 75°E–100°E). Results show that no model can

Simulating SST Variability by Forcing a Coupled Model With Observed Wind Stress

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract Ocean general circulation models (GCMs) forced with observed surface atmospheric variability are widely used to simulate and investigate interannual variations in sea surface temperature (SST). However, imposing atmospheric thermodynamic forcing is physically inconsistent as SST usually drives air temperature and humidity.
