Observed Ionospheric Tidal Response to the Madden‐Julian Oscillation

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The Madden‐Julian Oscillation (MJO) is the dominant mode of intraseasonal variability in the tropical troposphere and known to affect the tidal activity in the mesosphere and lower thermosphere (MLT). Using Constellation Observing System for Meteorology, Ionosphere, and Climate‐2 (COSMIC‐2) Global Ionospheric Specification electron density ...

Temporal and Spatial Evolution of Cold Ions in the Inner Magnetosphere During Large Magnetic Storms

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract To examine the temporal and spatial evolution of cold ions within the inner magnetosphere during geomagnetic storms, we conducted superposed epoch analyses on the electron density (Ne) and the partial ion densities of H+, He+, and O+ within the instrument frame energy range of 1–10 eV, using data obtained from the Van Allen Probes.

Salinity Contribution to Regional Sea Level Trends in the Tropical Southwestern Pacific Ocean Over 2014–2023

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Steric sea‐level has been identified as the main driver of regional sea‐level trends. Altimetry‐based spatial patterns vary as a function of space and time. Thermosteric (temperature‐related) sea‐level trends have generally been found to be more important than the halosteric (salinity‐related) trends.

Whistler‐Mode Waves and Associated Electron Distributions in Jupiter's Middle and Outer Magnetosphere

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Whistler‐mode waves play a crucial role in shaping magnetospheric electron dynamics. Using Juno's observations, we investigate these waves in Jupiter's post‐midnight‐to‐dawn magnetosphere, spanning 20–80 Jupiter radii. Our survey reveals that whistler‐mode waves predominantly occur in the lobes, while the magnetodisk remains largely devoid of ...

Nonlinear Acceleration of Ultrarelativistic Electrons in the Outer Radiation Belt Disrupted by Transverse Wave Modulations

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Whistler‐mode waves scatter ultrarelativistic electrons in the radiation belts and accelerate them through resonant interactions. In simplified models, nonlinear phase trapping by high‐amplitude waves can increase electron energy by several MeV within seconds.
