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.

Atmosphere‐Ocean Tendency Corrections Improve Seasonal Prediction Skill of CanESM5

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract This study examines impacts on prediction skill of empirically‐derived tendency corrections (TC) to climatological seasonal cycle biases in retrospective seasonal forecasts from the Canadian Earth System Model version 5 (CanESM5). A novel aspect is that TC are applied simultaneously in the modeled atmosphere and ocean, rather than to either ...

Environmental control of cloud-to-ground lightning polarity in severe storms [PDF]

, 2009
In this study, it is hypothesized that the mesoscale environment can indirectly control the cloud-to-ground (CG) lightning polarity of severe storms by directly affecting their structural, dynamical, and microphysical properties, which in turn directly ...

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).

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.

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 ...
