Real-time extraction of the Madden-Julian oscillation using empirical mode decomposition and statistical forecasting with a VARMA model [PDF]
A simple guide to the new technique of empirical mode decomposition (EMD) in a meteorological-climate forecasting context is presented. A single application of EMD to a time series essentially acts as a local high-pass filter.

Increasing Population and Cropland Exposure to Human‐Induced Sequential Heatwave‐Downpour Events
Abstract Compound sequential heatwave‐downpour (SHD) events, characterized by abrupt shifts from heatwaves to heavy rainfall, pose serious threats to health, infrastructure, and agriculture. However, the anthropogenic influence on the increasing trend of SHD events is poorly understood, and projections also exhibit large uncertainties.

Vertical Moist Thermodynamic Structure of the Madden–Julian Oscillation in Atmospheric Infrared Sounder Retrievals: An Update and a Comparison to ECMWF Interim Re-Analysis [PDF]
The large-scale vertical moist thermodynamic structure of the Madden–Julian oscillation (MJO) was documented using the first 2.5 yr (2002–05) of version 4 atmospheric specific humidity and temperature profiles from the Atmospheric Infrared Sounder (AIRS).

Impact of Intraseasonal Coastal Trapped Waves on Upwelling in the Northern Gulf of Guinea
Abstract We investigate the impact of equatorially‐forced intraseasonal coastal trapped waves (CTWs) on temperature variability in the Northern Gulf of Guinea (NGG) upwelling system, using a high‐resolution (1/36°) regional ocean model simulation spanning 2008–2017.

Equatorial upper-ocean dynamics and their interaction with the West African monsoon [PDF]
Zonal wind anomalies in the western equatorial Atlantic during late boreal winter to early summer precondition boreal summer cold/warm events in the eastern equatorial Atlantic (EEA) that manifest in a strong interannual Atlantic cold tongue (ACT ...

Observation‐Based Estimates of Vertical Velocity in the Tropical Upper Oceans
Abstract Equatorial upwelling plays a crucial role in regulating regional climate variability and biological productivity from seasonal to interannual time scales. Typically, sea surface temperature or surface chlorophyll anomalies are used as proxies for upwelling because of the challenges in directly measuring vertical velocities.

Initiation of Boreal Summer Intraseasonal Oscillation: Dynamic Contribution by Potential Vorticity
Abstract Potential vorticity (PV) thinking conceptually connects the upper-level (upper troposphere in the extratropics and middle troposphere for the tropics) dynamical process to the lower-level process. Here, the initiation mechanism of the boreal summer intraseasonal oscillation (BSISO) in the tropics is investigated using PV ...

The Energy Exascale Earth System Model Version 3: 2. Overview of the Coupled System
Abstract The Energy Exascale Earth System Model version 3 (E3SMv3) represents the latest advancement in Earth system modeling developed by the U.S. Department of Energy (DOE). Building upon previous versions, E3SMv3 introduces significant updates across its coupled components to enhance capability and improve fidelity.
