The Influence of Interactive Sea Surface Temperatures on Self‐Aggregation in Channel Domain Radiative‐Convective Equilibrium

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Convective self‐aggregation describes the spontaneous organization of convection that occurs in radiative‐convective equilibrium (RCE) simulations. Here, we conduct RCE simulations coupled to 2‐ and 20‐m slab ocean models in a 3D channel domain to assess the influence of interactive sea surface temperatures (SST) on self‐aggregation.

Study of geopotential error models used in orbit determination error analysis [PDF]

The uncertainty in the geopotential model is currently one of the major error sources in the orbit determination of low-altitude Earth-orbiting spacecraft.

Persisting Modulation of Interdecadal Pacific Oscillation on Near‐Future Winter Precipitation Projections in Northern Europe

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract European winter precipitation profoundly influences regional hydroclimate, yet the relative roles of internal variability and external forcing in its decadal changes remain elusive. Using large‐ensemble climate simulations, we identify the Interdecadal Pacific Oscillation (IPO) as a potential driver of interdecadal changes in winter northern ...

Comparing Synoptic Pattern Evolution for Flash‐Flood‐Producing and Non‐Flash‐Flood‐Producing Mesoscale Convective Systems in the United States

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Understanding how the short‐term evolution of synoptic weather patterns influence Mesoscale Convective Systems (MCSs) is essential, as these systems are responsible for over half of central U.S. flash floods, leading to substantial socioeconomic and water resource management impacts. This study analyzes long‐term MCS data, flash flood reports,

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 ...

Evaluation of a Soviet-Era Gravimetric Survey Using Absolute Gravity Measurements and Global Gravity Models: Toward the First National Geoid of Kazakhstan

Geosciences
Determining a high-precision national geoid is a fundamental step in modernizing Kazakhstan’s vertical reference system. However, the country’s vast territory, complex topography, and limited coverage of modern terrestrial and airborne gravimetric ...

Warming of the Mid‐Troposphere Driven by Evapotranspiration During Compound Heatwave and Drought Events

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract During compound heatwave and drought events (CHDE), a significant amount of soil moisture is released into the atmosphere through evapotranspiration. In this study, we used multi‐source atmospheric water vapor isotope data sets, including satellite and ground‐based observations, to investigate the role of evapotranspired water vapor (EWV ...

Interdecadal Increase in Spring‐To‐Summer Persistence of Central American Precipitation Anomalies

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Central American agriculture and ecosystems are acutely sensitive to rainfall that spans the spring‐summer growing window, yet most studies still evaluate each season in isolation. Here we demonstrate that, since the 2000s, Central American precipitation anomalies in spring have become more likely to persist into summer‐a shift that single ...

Differentiating Average and Extreme Extra‐Tropical Cyclones by Their Vertical Tilt and Potential Vorticity Structure

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This study compares the vertical tilt and potential vorticity (PV) $(PV)$ structure of average and extreme extra‐tropical cyclones (ETCs) in the Northern Hemisphere during the cold season (October–March) in ERA5 reanalysis. Vertical tilt is quantified using a novel two‐component (directional and lateral, aligned with and across cyclone motion)
