Eruption of a Million-Kelvin Warm Magnetic Flux Rope on the Sun
The Astrophysical JournalSolar magnetic flux rope (MFR) plays a central role in the physics of coronal mass ejections (CMEs). It mainly includes a cold filament at typical chromospheric temperatures (∼10,000 K) and a hot channel at high coronal temperatures (∼10 MK).

Radio Sounding Determination of Two‐Dimensional Plasma Structure Velocity
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract The Mars spacecraft Tianwen‐1 transmitted radio signals to Earth for its orbit determination. The frequencies of the radio signals exhibited sharp variations when an ICME passed through the Mars‐Earth signal path on 18 June 2021. These sharp variations were observed at different ground stations at different times. This was most probably caused

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.Abstract Tropical ocean evaporation is the dominant source of moisture for global precipitation. However, the dependence of evaporation‐temperature sensitivity on ocean surface radiative properties has not been quantified in the fully coupled modeling framework.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

Altitude Dependence of Quasi‐Static Potential Drop: The Effect of Ionospheric Protons
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Using an improved kinetic model that incorporates cold ionospheric protons and oxygen ions, we investigate the factors controlling the altitude range of the auroral acceleration region (AAR). In this model, parallel electric fields are generated via Dispersive Alfven Wave‐ Modified electron Acoustic Wave (DAW‐MEAW) coupling and sustained by ...

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The upper thermosphere is important in the context of space weather, but continuous monitoring of the thermosphere at high latitudes remains limited despite its strong variations associated with geomagnetic activity. Orthohelium, He(23S), is found from the upper thermosphere to lower exosphere, and is a promising tracer of atmospheric dynamics.

High‐ and Low‐Latitude Insolation Forcing Drives the Half‐Precession Cycle in Winter Arctic Sea Ice
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The half‐precession cycle is a key climatic signal in global climate system, linking high‐ and low‐latitude climate variability and bridging orbital‐ and millennial‐scale climate changes. While it characterizes tropical insolation, its origin in high‐latitude climate records remains unclear. Based on a transient climate simulation spanning the
