Explaining Pan‐Atlantic Cold and Windy Extremes Using an Analog‐Based Approach

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 10, 28 May 2025.
Abstract The occurrence of cold spells over different regions of North America has been previously linked to windy extremes over Western Europe. These so‐called pan‐Atlantic extremes are necessarily mediated by the North Atlantic circulation. It is known that the Atlantic storm track modulates European windstorm occurrence, but it is unclear whether ...

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

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

Characteristics of Super Atmospheric Rivers Associated With Explosive Extratropical Cyclones Over the Northern Pacific Ocean

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract Atmospheric Rivers (ARs) are elongated, narrow corridors of concentrated moisture in the atmosphere, transporting significant amounts of water vapor outside the tropics and causing heavy precipitation. ARs are often accompanied with explosive extratropical cyclones (EECs) over oceans.

Remote Impact of Typhoon In‐Fa on the Catastrophic Flood Over Henan, Inland of China in July 2021

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract It has been shown the catastrophic flood in Henan, inland of China in July 2021, was strongly influenced by Typhoon In‐Fa in the western North Pacific. However, the remote impact of Typhoon In‐Fa via the monsoonal flow has not yet been clearly addressed.

Disentangling Regional Drivers of Top Antarctic Snowfall Days With a Convolutional Neural Network

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract Snowfall is the primary contributor to Antarctic surface mass balance. Identifying regional‐scale mechanisms that drive heavy snowfall provides context for changes in Antarctic surface mass balance in a warmer climate. We compare drivers of top snowfall days across five Antarctic regions using machine learning and traditional synoptic ...

True Polar Wander Driven by Artificial Water Impoundment: 1835–2011

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract Artificial water impoundment contributed significantly to global mean sea level change during the 20th century and is included in recent studies of the budget of 20th century true polar wander (TPW). We adopt a recent global database of water impoundment that accounts for 72% of an integrated global volume estimate and compute the associated ...

A model intercomparison analysing the link between column ozone and geopotential height anomalies in January [PDF]

Atmospheric Chemistry and Physics, 2008
A statistical framework to evaluate the performance of chemistry-climate models with respect to the interaction between meteorology and column ozone during northern hemisphere mid-winter, in particularly January, is used.
