A Statistical Study of the Decreased TEC Region During Summer at Northern High Latitudes
Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Based on the vertical Total Electron Content (TEC) data observed by the Global Navigation Satellite System in the northern hemisphere, a large area of low plasma density during summer at high latitudes, termed decreased TEC region, was investigated statistically between 2014 and 2024.

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Numerous studies demonstrated a huge potential for ionospheric total electron content (TEC) measurements to be included in earthquake and tsunami risk assessments. However, up to now, only a few methodologies or tools can be used in near‐real‐time (NRT) for these purposes.

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Seasonal variations in glacier motion are influenced by water supply and associated changes in subglacial drainage systems. Few studies have investigated how year‐to‐year variations in glacier runoff modify these seasonal speed patterns. We analyze more than 200 correlations between glacier surface speed and runoff for 77 glaciers (∼3,070 km2)

The Cross‐Over From Viscous to Inertial Lengthscales in Rapidly‐Rotating Convection
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Convection is the main heat transport mechanism in the Earth's liquid core and is thought to power the dynamo that generates the geomagnetic field. Core convection is strongly constrained by rotation while being turbulent. Given the difficulty in modeling these conditions, some key properties of core convection are still debated, including the

Importance of Longwave Radiative Forcing by Icy Clouds in Maintaining Miocene High‐Latitude Warmth
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract During the early‐to‐middle Miocene, global mean surface temperature (GMST) was approximately 8°C warmer than preindustrial, with a greater temperature increase in polar regions than the tropics. However, existing Miocene simulations underestimate this warmth, particularly in northern high latitudes.

Mantle Exhumation and Post‐Rift Magmatism at an Oblique Magma‐Poor Continental Margin
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Continental breakup is a fundamental tectonic process, which leads to seafloor spreading and the generation of oceanic crust. However, the current understanding of continental margins, based largely on 2‐D seismic transects, is inadequate to capture the spatial complexity of crustal evolution.
