Ageostrophic Velocities of Curved Ocean Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Ageostrophic velocities at ocean fronts play a key role in ventilating the upper ocean. The overturning circulation driven by cross‐front ageostrophic flow is widely recognized as the major mechanism of vertical transport, but the role of along‐front ageostrophic velocities remains underrepresented in existing theory.

Seasonal and Interannual Variability of Antarctic Bottom Water Downstream of the Four Key Formation Regions

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Antarctic Bottom Water (AABW) is a cold, dense water mass formed around Antarctica that ventilates the global abyssal ocean. Recent studies have reported widespread warming, freshening, and thinning of AABW, yet its temporal variability remains poorly constrained because of sparse observations.

Upstream influence of midlatitude jet stream biases in boreal summer

Atmospheric Science Letters
Climate models exhibit biases in the mean state and in variability across different regions of the Earth. For example, atmosphere‐only models have a poleward bias in summertime jet streams across the Northern Hemisphere (NH).

Heat Extremes Within Hot Summer Seasons Intensify More Than in Average Summers Under Global Warming

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract The intensity and persistence of heat extremes increase in a warming climate. Warmer temperatures imply more hot days and longer hot periods per summer. However, beyond summer mean temperature change, changes in the timing of hot days within the season increase the likelihood of long‐lasting uninterrupted hot periods in many mid‐latitude ...

Influence of Rossby waves on primary production from a coupled physical-biogeochemical model in the North Atlantic Ocean [PDF]

Ocean Science, 2008
Rossby waves appear to have a clear signature on surface chlorophyll concentrations which can be explained by a combination of vertical and horizontal mechanisms.

Observations of High‐Frequency Internal Waves Near Submesoscale Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Nonlinear high‐frequency internal waves (HIWs) can occur at oceanic frontal interfaces but are rarely observed directly. This study presents field observations of HIWs near submesoscale fronts (SFs) in the northern Gulf of Mexico. A marine X‐band radar detected a series of organized bands, with a spacing of 50 ∼ 300 m, near SFs.

Surface Thermal Tides and Radiative Adjustment in Venus's Deep Atmosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Thermal tides on Venus have been extensively studied near the cloud tops, where their three‐dimensional structure and contribution to the atmospheric momentum budget have been characterized from temperature and wind fields. However, their downward propagation and influence within the deep atmosphere remain uncertain, and their behavior in the ...

Diagnosing Submesoscale Divergence From Sea Surface Height

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Surface Water and Ocean Topography satellite mission now delivers global sea surface height (SSH) observations at scales fine enough to resolve submesoscale eddies (<50 km). At these scales, the traditional geostrophic approximation, commonly used to infer surface currents from SSH, no longer holds.

Attribution of the Record‐Breaking June 2024 Eastern Mediterranean Heatwave: Contrasting Roles of Soil Moisture in Anthropogenic Forcing and Natural Variability

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In June 2024, the Eastern Mediterranean experienced its hottest June since 1960. However, the relative contributions of anthropogenic forcing and natural variability to this event, and the roles of atmospheric circulation and soil moisture, remain unclear.
