Laboratory Observations of Hall Magnetic Field in Electron‐Only Magnetic Reconnection With a Guide Field

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Recently, electron‐only reconnection, in which there is no obvious ion bulk flow and ion heating, has been pervasively observed in the Earth's magnetosphere. In this Letter, we realize electron‐only reconnection with a guide field in the Keda Linear Magnetized Plasma (KLMP) device.

Evaluation of expected solar flare neutrino events in the IceCube observatory

, 2015
Since the end of the eighties and in response to a reported increase in the total neutrino flux in the Homestake experiment in coincidence with a solar flare, solar neutrino detectors have searched for solar flare signals.

Multi-timescale Solar Cycles and the Possible Implications

, 2010
Based on analysis of the annual averaged relative sunspot number (ASN) during 1700 -- 2009, 3 kinds of solar cycles are confirmed: the well-known 11-yr cycle (Schwabe cycle), 103-yr secular cycle (numbered as G1, G2, G3, and G4, respectively since 1700);

Anticipating Solar Flares

Solar Physics
Abstract Solar flares commonly have a “hot onset precursor event” (HOPE), detectable from soft X-ray observations. To detect this requires subtraction of pre-flare fluxes from the non-flaring Sun prior to the event, fitting an isothermal emission model to the flare excess fluxes by comparing the GOES passbands at 1 – 8 Å and 0.5 – 4 Å, and ...

Sensitivity of Wintertime Arctic Black Carbon to Removal Processes and Regional Alaskan Sources

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 7, 16 April 2025.
Abstract Air pollutants are primarily transported from midlatitude emission regions in winter and early spring, leading to elevated concentrations of aerosols, including black carbon (BC), in the Arctic, a phenomenon known as Arctic haze. The Weather Research and Forecasting model coupled with chemistry is used to investigate potential causes of ...

The Eddy Flux Transport of the Magnetohydrodynamic Quasi‐Geostrophic Disturbances

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract The classic Eliassen‐Palm (E‐P) flux in the geophysical fluid dynamics is a vector to qualify the eddy momentum and heat flux transport by Rossby waves in the latitude‐height plane. In this investigation, we derive two magnetic E‐P fluxes to quantify the eddy energy transport by magnetic Rossby waves by using magnetohydrodynamic quasi ...

Observations of Geomagnetic Crochet at High‐Latitudes Due To X1.5 Class Solar Flare on 3 July 2021

Space Weather
On 3 July 2021, an X1.5 solar flare from the National Oceanic and Atmospheric Administration solar Active Region AR12838 (24°N, 88°W) occurred at 14:18 UT, peaked at 14:29 UT, and decayed at 14:34 UT. The study of this X1.5 solar flare is significant due
