Comparative Analysis of Ionospheric Responses to Ultra‐Fast Kelvin Waves With Wavenumbers 1, 2, and 3

Space Weather, Volume 24, Issue 1, January 2026.
Abstract We employed zonal wind data from Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics Doppler Interferometer, equatorial electrojet (EEJ) measurements from Jicamarca (12°S, 77°W), and global ionospheric total electron content (TEC) maps to investigate the effects of ultra‐fast Kelvin waves (UFKW) with zonal wavenumbers 2 and 3 ...

The Relationship Between the Magnetometer Data Derived GIC Index and Measured GIC in High Voltage Transformers in Australia

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks. It is often difficult to obtain transformer GIC data so ground based magnetometer data may be used to estimate the transformer GIC via complex modeling of both network and ...

Space Weather and Low‐Altitude Drone Economy

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Unmanned Aerial Vehicles (UAVs) are becoming integral to the emerging low‐altitude economy, operating primarily below 3,000 m for applications such as logistics, inspection, precision agriculture, and urban air mobility. The safe and reliable operation of UAVs depends critically on communication, navigation, and surveillance (CNS) systems ...

Predicting Dual‐Satellite Ionospheric Radial Currents From Single‐Satellite Observations With a BiLSTM Model

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Ionospheric radial currents (IRC) can be derived using two methodologies: (a) the single‐satellite approach: Single‐IRC is deduced from magnetic field data of a single satellite (Swarm‐A); (b) the dual‐satellite approach: Dual‐IRC is calculated by coordinated magnetic field measurements of a pair of satellites (Swarm‐A and ‐C).

“Oxygen starvation” of the atmosphere

Solar-Terrestrial Physics
Since the discovery of the phenomenon of abnormal cooling and sinking of the middle and upper atmosphere in 1993–1998, two concepts have developed which explain its origin by man-made processes.

Upwelling Metallic Ions Producing Valley Region Irregularities Over Low Latitude During the 2025 New Year Magnetic Storm

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Valley region irregularities (VRIs) have been previously investigated using radar, ionosonde, and rocket‐borne in situ observations. In this paper, based on a joint observational experiment by lidar and radars performed in Hainan, China, we report a case of low‐latitude VRIs generated in association with uplifted metallic ions for the first ...

Stratosphere‐Troposphere Exchange of Water Vapor Based on Observations and Reanalyses

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract This study provides the first estimates of the global stratosphere‐troposphere exchange (STE) of water vapor (H2O) using the lowermost stratosphere mass budget approach. Observationally derived H2O fluxes across the isentropic surface fitted to the tropical tropopause are −1.16 ± 0.20 Pg/yr in the Northern Hemisphere extratropics, −0.94 ± 0.18
