Accuracy assessment of high and ultra high-resolution combined GGMs, and recent satellite-only GGMs – Case studies of Poland and Ethiopia

Reports on Geodesy and Geoinformatics
The launch of dedicated satellite gravity missions (CHAMP, GRACE, GOCE, and GRACE–FO), as well as the availability of gravity data from satellite altimetry and terrestrial/airborne gravity measurements have led to a growing number of Global Geopotential ...

Unprecedented Wetting Over Western Central Asia Dominated by Internal Climate Variability

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Spring precipitation over western Central Asia (SCAP) experienced an abrupt and unprecedented wetting during 1988–2007, yet the relative contributions of external forcing and internal variability to this change and the underlying drivers remain unclear.

Geoid modeling based on global geopotential models and digital terrain models

This paper presents a methodology for high-resolution, centimeter-accuracy geoid modeling in local areas using only publicly available data, eliminating the need for terrestrial gravity measurements. The approach synthesizes long- and short-wavelength components of the height anomaly, along with ellipsoidal correction, to efficiently determine geoid ...

Influence of the Polar‐Eurasia Pattern on Interannual Variations in Extratropical Transition of Western North Pacific Tropical Cyclones

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract This study investigates climate drivers influencing interannual changes in the extratropical transition (ET) of western North Pacific tropical cyclones (TCs) during July–October from 1979 to 2024. We find a pronounced relationship between the fraction of TCs experiencing ET (ETTCs) to all TCs and the Polar‐Eurasia (POL) pattern.

Unprecedented Extreme Dust Storm Triggered by Stratosphere‐Troposphere Interactions

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract An unprecedented dust storm struck southern China in April 2025, affecting hundreds of millions of people in regions rarely impacted by dust storms and challenging existing understanding of lower‐latitude dust storms. Here, we show that polar stratospheric signals enabled this event by modulating tropospheric teleconnection, revealing an ...

Atmospheric and Oceanic Influences on Seasonal Atlantic Tropical Cyclone Landfall Probability

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Modes of tropical atmosphere‐ocean variability, such as the El Niño–Southern Oscillation (ENSO) and Atlantic Meridional Mode (AMM), are useful predictors of seasonal Atlantic tropical cyclone (TC) frequency. However, the percentage of TCs that make landfall has varied widely year‐to‐year since 1980 (13%–75%) and is weakly correlated with the ...
