Measuring the gravity potential between two remote sites with CVSTT technique using two hydrogen clocks

Geo-spatial Information Science
According to General Relativity Theory (GRT), by comparing the frequencies between two precise clocks at two different stations, the gravity potential (geopotential) difference between the two stations can be determined due to the gravity frequency shift

Using Neural Network Models and Synoptic Circulation Patterns to Project Future Changes in US Tornado Activity

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Studying the impacts of climate change on tornadoes remains challenging, partly because global climate models (GCMs) struggle to resolve the small‐scale atmospheric phenomena relevant to tornadogenesis. To overcome this problem, this study uses self‐organizing maps (SOMs) to identify synoptic‐scale patterns of atmospheric circulation that are ...

Characterization of the Regional Climate and Large‐Scale Atmospheric Circulation in the Caspian Sea Region During the Last Glacial Maximum

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 16, 28 August 2025.
Abstract The Caspian Sea is the largest inland water body on Earth. Still, this region is often not considered in paleoclimate model analyses. In this study, we examine the climate of the Caspian Sea region during the Last Glacial Maximum (LGM) and its driving large‐scale atmospheric circulation using data from two global climate models (AWI‐ESM‐1‐1LR ...

On Applicability of the Radially Integrated Geopotential in Modelling Deep Mantle Structure

Geosciences
A long-wavelength geoidal geometry reflects mainly lateral density variations in the Earth’s mantle, with the most pronounced features of the Indian Ocean Geoid Low and the West Pacific and North Atlantic Geoid Highs.

North American Monsoon Response to Antecedent Soil Moisture and Snow in the Colorado Plateau

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 16, 28 August 2025.
Abstract This study explores the relationship between spring soil moisture and snowpack in the Colorado Plateau (CP) and the onset of the North American Monsoon (NAM) using reanalysis data. We find that increased spring soil moisture in the CP corresponds to later NAM onset dates throughout much of the southwestern United States (US) and northwestern ...

Delayed Impacts of Spring Soil Moisture in the Tibetan Plateau on Early‐Summer Air Temperature in the Northern East Asia

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract The northern East Asia (NEA) is suffering from significant temperature anomalies in recent years and the formation mechanisms remain unclear yet. With focus on non‐local effects of Tibetan Plateau soil moisture (TPSM), this study explores the close linkage between anomalies of TPSM in boreal spring and air temperature of NEA (NEAT) in early ...

On possibilities of improving the accuracy of the geocentric gravitational constant GM by combining SLR and atomic clocks measurements

Contributions to Geophysics and Geodesy
Nowadays, the geocentric gravitational constant GM is determined by solving equations of motion for trajectories of artificial satellites measured by Satellite Laser Ranging (SLR). The estimated value of GM and its uncertainty 398600441.8 ± 0.8×106 m3s−2

Impacts of Indo‐Pacific Sea Surface Temperature Versus Internal Atmospheric Variability on the South China Sea Summer Monsoon

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract The South China Sea (SCS) summer (i.e., June–August [JJA]) monsoon experiences strong interannual variability, which is modulated by the western North Pacific subtropical high (WNPSH). Large‐scale steady‐state atmospheric circulations linked to JJA mean Indian Ocean basin and preceding winter–spring (i.e., January–March [JFM]) and JJA mean ...

Geopotential difference determination using optic-atomic clocks via coaxial cable time transfer technique and a synthetic test

Geodesy and Geodynamics, 2015
According to the general theory of relativity, two clocks placed at two different positions with different geopotentials run at different rates. Thus one can determine the geopotential difference between these two points by comparing the running rates of

Human Enhanced Moisture Transport Exacerbated the Extreme Precipitation in Northern China

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Although previous studies suggest anthropogenic forcing may influence extreme precipitation probability, few have specifically investigated the human influence on moisture transport. Here, we leverage the 2023 record‐breaking summer precipitation in Northern China (NC) to address this gap.
