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)

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 ...

Comparison of satellite derived dynamical quantities in the stratosphere of the Southern Hemisphere [PDF]

The proceedings are summarized from a pre-MASH planning workshop on the intercomparison of Southern Hemisphere observations, analyses and derived dynamical quantities held in Williamsburg, Virginia during April 1986.

The Atmosphere's Substantial Role in Interannual Variability of Earth's Energy Imbalance

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earth's Energy Imbalance (EEI) is a key metric to quantify climate change. While the ocean absorbs most excess heat, the atmosphere contributes only 1%–2% to the long‐term mean of EEI. However, our analysis of observational data demonstrates that variations in the atmosphere's energy content play a much larger role in interannual variations of

Resolving Convection Doubles Sahel's Contribution to Global Dust Emission During the Monsoon Season

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Current climate models struggle to capture the mean state and variability of dust emissions. This is partially due to their inability to resolve convection, a consequence of their relatively coarse spatial resolution. Via analysis of output from an offline dust emission scheme forced with output from a global storm‐resolving model, we show ...

The Role of Near Solstice Solar Radiation on the Pacific Northwest Heatwave of June 2021

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract In late June 2021, the Pacific Northwest experienced a severe heatwave, shattering temperature records and making worldwide news. The extreme temperatures have been attributed to an anomalously strong atmospheric block, high moisture content of upstream air, and dry soils.

Ice Multiplication Modulates the Medicane's Track and Thermodynamic Evolution

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Medicanes are high‐impact weather systems in the Mediterranean region, associated with floodings, severe damage and human casualties. While there has been continuous effort to understand the dynamic aspects of these systems, little is known about the underlying cloud‐scale processes, which cannot be resolved explicitly, consisting a notorious ...

Pinatubo eruption winter climate effects: Model versus observations [PDF]

Large volcanic eruptions, in addition to the well-known effect of producing global cooling for a year or two, have been observed to produce shorter-term responses in the climate system involving non-linear dynamical processes.

Evaluation of global geopotential models in determining the quasi-geoid for Southern Africa

Survey Review, 2007
Precise geoid models are needed to enable GPS-derived heights to be converted to the local height datum. A major component of these models is a global geopotential model. Several candidate models are assessed in the context of forming the basis for a regional quasi-geoid for Southern Africa. These candidates include the EGM96 and models based upon data
