A dynamical framework for the origin of the diagonal South Pacific and South Atlantic convergence zones [PDF]

, 2015
The South Pacific Convergence Zone (SPCZ) and South Atlantic Convergence Zone (SACZ) are diagonal bands of precipitation that extend from the equator southeastward into the Southern Hemisphere over the western Pacific and Atlantic Oceans, respectively ...

Weather Regimes Preclude the Observation of a Southern Annular Mode Signal in Two Coastal East Antarctic Ice Cores

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract The Southern Annular Mode (SAM) represents the dominant pattern of climate variability in the extratropical Southern Hemisphere. However, its signature in coastal East Antarctic ice core records is unclear. A daily synoptic typing data set for the southern Indian Ocean constructed using self‐organizing maps on 500 hPa daily geopotential height

Compound Mesoscale Convective Systems and Low‐Pressure Systems in Tropical Monsoon Regions: Assessing Their Meteorology and Precipitation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Mesoscale convective systems (MCS) and low‐pressure systems (LPS) are both strongly associated with precipitation across the regions where they occur, particularly within global monsoon systems; however, their co‐occurrence and its relationship to precipitation have not been systematically examined.

The Madden-Julian Oscillation in NCEP Coupled Model Simulation

Terrestrial, Atmospheric and Oceanic Sciences, 2009
This study documents a detailed analysis on the Madden-Julian Oscillation (MJO) simulated by the National Centers for Environmental Prediction (NCEP) using the Global Forecast System (GFS) model version 2003 coupled with the Climate Forecast System model

Moisture‐Flux‐Sensitive Convection Strengthens MJO Preconditioning

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Despite decades of research, the Madden‐Julian Oscillation (MJO) remains challenging for global prediction systems, partly because its representation is sensitive to convection‐environment interactions. We evaluate a new prognostic convective closure in NOAA's Unified Forecast System (UFS) that incorporates large‐scale moisture‐flux ...

Distinct Impacts of Western and Eastern Maritime Continent Convection on the South China Sea Tropical Cyclone Activity in Autumn

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Convection anomalies in the eastern and western Maritime Continent (MC) during boreal autumn exhibit distinct characteristics and climatic effects, but their impacts on South China Sea (SCS) tropical cyclones (TCs) remain unclear. Here we reveal that the eastern MC convection mode, although it explains less convection variance, exerts strong ...

Fast and slow Kelvin waves in the Madden-Julian Oscillation of a GCM [PDF]

, 1999
The structure of the Madden-Julian Oscillation (MJO) in an 1800-day integration of the Hadley Centre Unified Model was analysed, and interpreted within a Kelvin wave framework. The model was forced with constant equinoctial (March) boundary conditions so

Eastward Propagation of Anomalous Indo–Pacific Walker Circulation During ENSO Transition

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract By analyzing the zonal mass streamfunction over the equatorial Indo–Pacific region in the period 1979–2024, we found that during the decaying phase of 13 out of 31 El Niño‐Southern Oscillation (ENSO) events, the anomalous Indo–Pacific Walker Circulation (IPWC) propagates steadily eastward across the warm pool. Vertical velocity, precipitation,
