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 ...

The Effect of Arctic Sea‐Ice Loss on Extratropical Cyclones

, 2023
Taking advantage of the Polar Amplification Model Intercomparison Project simulations and using a Lagrangian objective feature tracking algorithm, we determine the response of extratropical cyclones to sea-ice loss and consequent weakening of the equator-

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.

Large-scale circulation drives atmospheric river landfall in the western United States

Communications Earth & Environment
Atmospheric rivers cause extreme precipitation and sustain water resources in the western United States. Their occurrence has often been attributed to extratropical cyclones.

Objective Algorithm for Detection and Tracking of Extratropical Cyclones in the Southern Hemisphere

Atmosphere
In this study, we propose an easy and robust algorithm to identify and track extratropical cyclone events using 850 hPa relative vorticity data, gaussian filter and connected-component labeling technique, which recognize the cyclone as areas under a ...

Contribution of Tropical Cyclones to Hourly Precipitation Extremes in the Contiguous United States

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Tropical cyclones (TCs) are major drivers of contiguous United States (CONUS) flooding, yet their contribution to hourly precipitation extremes remains poorly quantified. Here we link observations from 420 gauges (1980–2024) with TC track data to attribute extreme hourly precipitation to both local and remote TCs.

The extratropical transition of tropical cyclone Lili (1996) and its crucial contribution to a moderate extratropical development

, 2005
The transition that a tropical cyclone experiences as it moves into the extratropical environment (known as extratropical transition) can result in the decay or intensification of a baroclinic cyclone.
