Ionospheric Vertical Plasma Drifts Over South America: Long‐Term Multi‐Instrument Observations and TIEGCM and WACCM‐X Evaluations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present the first comprehensive multi‐instrument climatological study of quiet‐time equatorial F‐region vertical plasma drifts across South America, a region where the magnetic declination angle varies significantly. Our analysis of well‐established long‐term ground‐based data sets from the Jicamarca incoherent scatter radar spanning 1968 ...

Ion Anisotropy in Earth's Magnetotail: Importance of High‐Energy Ions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The reconfiguration of the magnetotail current sheet during substorms often includes the formation of a thin current sheet (TCS) with a strong magnetic field line tension force. This force cannot be balanced by isotropic plasma pressure gradients, and force balance in such a TCS requires ion anisotropy and/or agyrotropy of plasma pressure.

Reinvestigating the Nightside Ionosphere of Mars With 8 Years of Mars Express and MAVEN Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Tailward ion escape in the nightside magnetotail is one of the dominant paths of ion escape from Mars. The Martian nightside ionosphere can serve as a major reservoir for this escape channel, but its global distributions and dependence on the upstream solar wind have not been fully investigated due to observational limitations.

Cold Pool Formation Over the Taiwan Bank Driven by Shoaling Internal Tides

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Cold, saline, and chlorophyll‐rich surface waters are frequently observed over the Taiwan Bank in the southern Taiwan Strait, forming a distinct feature referred to as the Green–Cold Pool (GCP). Despite its ecological importance, the physical mechanisms sustaining this cold pool remain unclear.

Buoy Observations of Ocean Swell Propagation Across the Pacific Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract A network of more than 300 drifting wave buoys is used to study the propagation of ocean swell across the Pacific Ocean. Swell events are identified at buoys in the Equatorial region and then tracked along Great Circle propagation paths both forward and backward in time.
