Accuracy of SYM-H and Dst indices as proxies of geomagnetic disturbances in Southern Europe

Journal of Space Weather and Space Climate
Dst and SYM-H indices were introduced by the scientific community to quantify the enhancement of the ring current encircling the Earth. Nowadays, those indices are also commonly used as space weather products to quantify the intensity of geomagnetic ...

Variation of Total Electron Content over Nepal during Geomagnetic Storms: GPS Observations

Russian Journal of Earth Sciences, 2023
Geomagnetic storms have very profound effects on the Total Electron Content (TEC) of the ionosphere. In order to investigate the equatorial and low-latitude ionospheric response to the geomagnetic storms of varying intensities, a detailed study of ...

Assessing the solar variability signature in climate variables by information theory and wavelet coherence

Scientific Reports, 2021
The present study aims to investigate the possible influence of solar/geomagnetic forcing on climate variables, such as the drought index, Danube discharge and large-scale atmospheric indices. Our analysis was performed separately for each season for two

Climate‐related exposures and seizures in children: A systematic review

Epilepsia, EarlyView.
Abstract Objective Climate‐related exposures, including air pollution, temperature extremes, humidity, and atmospheric conditions, are increasingly recognized as potential seizure triggers. As climate change intensifies, understanding the environmental contributors to pediatric seizure risk has important implications for anticipatory guidance and ...

Multi‐command wearable magnetic human‐machine interface enabled by low‐noise sensing and time‐series deep learning

InfoScience, EarlyView.
This study integrates a wrist‐worn sensing platform based on a low‐noise planar Hall magnetoresistive sensor with time‐series deep learning to enable long‐range, single‐sensor, multi‐command gesture recognition with high accuracy. Further evaluations show reliable generalization across different days, previously unseen users, wearing‐position ...

Comparison of K-index Calculations between Several Geomagnetic Stations during IQDs and IDDs [PDF]

Journal of Astronomy and Space Sciences, 2013
BOH magnetometer was installed at Mt. Bohyun in 2007 and has provided continuous dataset for 3-axis geomagnetic field over the South Korea. We have calculated real-time K-index based on BOH magnetic field data using well-known FMI method. Local K-index

Wavelet analysis of geomagnetic jerks [PDF]

, 2013
Geomagnetic jerks, or secular variation impulses, are abrupt changes in the slope of the first time derivative of the Earth's magnetic field. These changes occur on time scales of the order of a year. It has been demonstrated that the jerks might be more

Persistence and Dynamics of an Sq‐like Mid‐Latitude Current Vortex During the May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract The solar quiet (Sq) current system describes the mid‐latitude equivalent current under quiet geomagnetic conditions, but whether an Sq‐like vortex persists during intense storms remains unclear. Using dense East Asian magnetometer observations, including the Chinese Meridian Project, we reconstruct the storm‐time ionospheric equivalent ...
