Reconstructing the Geometry of a Hot Flow Anomaly With Bounding Jets in Magnetosheath
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract When interplanetary magnetic field discontinuities interact with planetary bow shocks, hot flow anomalies (HFAs) form in the solar wind and can extend into the magnetosheath. Here we reconstruct the three‐dimensional geometry of an HFA bounded by two jet regions in the terrestrial magnetosheath.

Comparison of simultaneous variations of the ionospheric total electron content and geomagnetic field associated with strong earthquakes [PDF]
Natural Hazards and Earth System Sciences, 2001 In this paper, perturbations of the ionospheric Total Electron Content (TEC) are compared with geomagnetic oscillations. Comparison is made for a few selected periods, some during earthquakes in California and Japan and others at quiet periods in ...

Statistical Characteristics of Stormtime Bursty Bulk Flows
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Bursty bulk flows (BBFs) play a significant role in transporting plasma earthward in the magnetotail. While their properties have been extensively studied, their behavior during geomagnetic storms needs further understanding. In this study, we investigate the stormtime characteristics of BBFs, and compare them to non‐stormtime, by performing a

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Interactions of solar wind dynamic pressure (SWDP) discontinuities with Earth's magnetosphere cause geomagnetic Sudden Commencements (SCs). Typically, positive/negative SCs occur at low latitudes due to enhancements/reductions in SWDP.

Periodicities in Solar Coronal Mass Ejections
, 2003 Mid-term quasi-periodicities in solar coronal mass ejections (CMEs) during the most recent solar maximum cycle 23 are reported here for the first time using the four-year data (February 5, 1999 to February 10, 2003) of the Large Angle Spectrometric ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract In May 2024, extraordinary solar activity triggered a powerful solar storm, impacting Earth and producing the extreme geomagnetic storm of 10‐11 May, the most intense since 2003. This had significant effects on the magnetosphere, leading to the creation of a new long‐lasting component of relativistic electrons and to flux changes in the South ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract The mesospheric semiannual oscillation (MSAO) in tropical zonal‐mean zonal winds exhibits a strong westward phase around March equinox. It has been thought that the migrating diurnal tide (DW1) plays a role in the initiation of this phase because DW1 peaks around this time and satellite observations have shown it to undergo wave breaking.
