Baroclinic Submesoscale Eddies in the Ross Ice Shelf Cavity Alter Heat Pathways to the Ice Base

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The influence of baroclinic submesoscale eddies on basal melting beneath Ross Ice Shelf remains poorly understood. We analyzed a 4.5‐year mooring record from the central cavity and identified seven eddy‐like events from variability in density, velocity, and thermohaline structure, with horizontal scales (∼11 km) characteristic of submesoscale ...

Stacked Cells Hypothesized for Jupiter's Atmosphere and Observed in Earth's Atmosphere

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Observations of Jupiter's atmosphere led to the hypothesis that each of Jupiter's jets is accompanied by vertically stacked overturning circulations, with their nodes at the altitude of the jet maximum. However, there is no established theory for how these stacked cells form.

Oceanic Spatio‐Temporal Patterns of Vertical Velocities in the Cape Basin and Agulhas Current Retroflection From Two Years of SWOT Altimetry

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite provides a groundbreaking view of sea surface height (SSH) across a 120‐km‐wide swath (20‐km nadir gap), opening new opportunities to reconstruct vertical velocities (w) $(w)$. Vertical motions play a central role in redistributing properties, influencing climate and ecosystems. Using the

Understanding Drought‐Induced Soil Moisture Feedback on Atmospheric Circulation: Observations and Simulation Experiments of the 2020 Western U.S. Drought

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract This study examines the large‐scale atmospheric response to reduced evapotranspiration during droughts in the Western U.S., using an observation‐based regression method and numerical experiments with a global climate model. We found that Western U.S.

Helicity: A Possible Indicator of Negative Feedback Initiation of Tropical Cyclone–Ocean Interaction

Earth and Space Science
The development of large‐scale vortex dynamo during tropical cyclogenesis through the mutual intensification of primary and secondary circulation in terms of helical evolution is well studied.

A Climatology of Coupled Tracks of Extratropical Cyclones and Mesoscale Convective Systems

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Weather in the midlatitudes is dominated by extratropical cyclones (ETCs) with horizontal length scales of roughly 1,000 km and mesoscale convective systems (MCSs), with horizontal length scales of roughly 100 km. This study investigates the multi‐scale interactions of these storms by comparing databases of Lagrangian tracks for both storm ...

Linkage Between Atmospheric Rivers and Overshooting Convection and Their Roles on UTLS Water Vapor During the North American Monsoon: Insight From DCOTSS

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Overshooting convection significantly impacts the composition of the upper troposphere and lower stratosphere (UTLS), yet its linkage to Atmospheric Rivers (ARs) remains poorly understood. This study investigates how ARs modulate environmental conditions and moisture distribution associated with overshooting convection in the central and ...

Western Disturbance Breaks and Extreme Spring Heat Over Northern India Linked to Quasi‐Stationary Rossby Waves

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Spring heat extremes over northern India in March coincide with critical wheat growth and pose disproportionate risks to yield and food security. March surface temperatures are modulated by Western Disturbances (WDs), midlatitude cyclonic systems embedded in the subtropical jet that typically bring rain and cooling.

Exploring the Influence of Equatorial Waves on a Record‐Breaking Extreme Precipitation Event in Central Sahel: Insights From Convection Permitting Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The floods of 01 September 2009 in Ouagadougou, Burkina Faso, were among the most severe in the Central Sahel's history, highlighting the region's persistent flood risk. This extreme precipitation event (EPE) was influenced by various atmospheric drivers, including Convectively Coupled Equatorial Waves (CCEWs).

ERA5‐Based Convective Environments Favorable for Tornadoes in Southern China

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Tornado occurrences vary significantly across regions in the globe, attributable in part to variations in regional climate and topography. This study analyzes the long‐term convective environments associated with tornadoes in southern China, a region previously identified as having the most favorable meteorological conditions for tornadoes ...
