Tracing Hailstone Development: Isotopic Evidence and Microphysical Variability in Texas Supercell Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Two supercell thunderstorms that occurred in Del Rio and Burkburnett, Texas in the spring of 2020 produced greater than 5 cm diameter hailstones. Fourteen hailstones, eight from Del Rio and six from Burkburnett, were cut in half along the maximum principal axis. Half the hailstone was dissected at 0.5 cm increments, providing 198 subsamples of

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 ...

Dynamic Versus Diabatic Controls on Atmospheric Variability in a Tropical Aquachannel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Synoptic‐ to planetary‐scale atmospheric variability in the tropics is a potential source of predictability worldwide. However, current weather prediction models struggle to fully capture this variability. Here, we conduct tropical aquachannel simulations using the ICOsahedral Nonhydrostatic model with horizontal grid spacings of 13 and 5 km ...

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 ...

Radar-Based Analysis of Convective Storms over Northwestern Italy

Atmosphere, 2011
Thunderstorms may cause large damages to infrastructures and population, therefore the possible identification of the areas with the highest occurrence of these events is especially relevant.

Differences in Lightning—Storm Microphysical Relationships in Subtropical South America Versus the Continental U.S. and Their Impact on Model Lightning Parameterizations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Satellite studies have shown that some of the deepest convection with high lightning flash rates occurs downstream of the Andes in subtropical South America (SSA). Using high resolution ground‐based observations in SSA, we explore the relationship between lightning and radar‐inferred storm microphysics.

U.S. Hail Frequency and the Global Wind Oscillation

Geophysical Research Letters, 2018
Changes in Earth relative atmospheric angular momentum can be described by an index known as the Global Wind Oscillation. This global index accounts for changes in Earth's atmospheric budget of relative angular momentum through interactions of tropical ...

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 ...

Debris Flows Suppressed Riverine Productivity and Respiration Following High‐Severity Wildfire on the Klamath River, California

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Wildfires alter terrestrial material and energy inputs to rivers, but impacts to ecosystem metabolism and dissolved oxygen (DO) are not well known due to few river ecosystem response studies during and after wildfires. In summer 2022, wildfire and heavy rains triggered debris flows into the Klamath River, where we compared immediate (days) and
