Energetic Compact Strokes as the Major Source of Downward Terrestrial Gamma‐Ray Flashes in Winter Thunderstorms

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Terrestrial gamma‐ray flashes (TGFs) are short bursts of intense gamma radiation associated with lightning discharges. Although thousands of TGFs have been observed from space, TGFs detected at ground level, known as downward TGFs, are still very limited, and their relationship with lightning discharge processes remains elusive. Here we report

Cosmic Rays and the Askaryan Effect Reveal Subsurface Structure and Buried Ice on the Moon

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract We present the first full‐wavelength numerical simulations of the electric field generated by cosmic ray impacts into the Moon. Billions of cosmic rays fall onto the Moon every year. Ultra‐high energy cosmic ray impacts produce secondary particle cascades within the regolith and subsequent coherent, wide‐bandwidth, linearly‐polarized radio ...

Generation of Quasi‐Periodic Dayside Medium Scale Traveling Ionospheric Disturbances (MSTIDs) by Intermittent Lobe Reconnection

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract The medium‐scale traveling ionospheric disturbances (MSTIDs) can be excited by many sources. Among those magnetic reconnection has been proposed as a potential driver for dayside MSTIDs, but direct evidence has been limited. Using ground‐based radar data from the Super Dual Auroral Radar Network on 14 December 2012, we observed quasi‐periodic ...

New Insights on the High Reconnection Rate and the Diminishment of Ion Outflow

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract The recently discovered electron‐only reconnection has abnormal features like lack of ion outflows and high reconnection rates. Using particle‐in‐cell simulations, we investigate their physical mechanisms. The reconnection rate, when normalized by ion parameters (Ri ${R}_{i}$), may appear anomalously high, whereas that normalized by electron ...

Observations of Kinetic‐Scale Magnetic Hole With Significant Energy Conversion in a Magnetotail Reconnection Diffusion Region

Geophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract Kinetic‐scale magnetic holes (KSMHs) are ubiquitous quasi‐steady magnetic structures and vital energy conversion channels in various space plasmas, for example, terrestrial foreshock and magnetopause reconnection region. However, the energy conversion mechanism within KSMHs remains unclear.
