Multiple Satellite Observations of Cloud Cover in Extratropical Cyclones

, 2013
Using cloud observations from NASA Moderate Resolution Imaging Spectroradiometer, Multiangle Imaging Spectroradiometer, and CloudSat-CALIPSO, composites of cloud fraction in southern and northern hemisphere extratropical cyclones are obtained for cold ...

Buoy Observations of Ocean Swell Propagation Across the Pacific Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract A network of more than 300 drifting wave buoys is used to study the propagation of ocean swell across the Pacific Ocean. Swell events are identified at buoys in the Equatorial region and then tracked along Great Circle propagation paths both forward and backward in time.

A diabatically-generated potential vorticity structure near the extratropical tropopause in three simulated extratropical cyclones

, 2015
The structure of near-tropopause potential vorticity (PV) acts as a primary control on the evolution of extratropical cyclones. Diabatic processes such as the latent heating found in ascending moist warm conveyor belts modify PV. A dipole in diabatically-

Extreme multi-basin flooding linked with extra-tropical cyclones

Environmental Research Letters, 2017
Fluvial floods are typically investigated as ‘events’ at the single basin-scale, hence flood management authorities may underestimate the threat of flooding across multiple basins driven by large-scale and nearly concurrent atmospheric event(s). We pilot

Benchmarking Regional Thermodynamic Trends in an AI Emulator, ACE2, and a Hybrid Model, NeuralGCM

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract AI models have emerged as potential complements to physics‐based models, but their skill in capturing observed regional trends with important societal impacts remains unexplored. Here, we benchmark satellite‐era regional thermodynamic trends, including extremes, in an AI emulator (ACE2) and a hybrid model (NeuralGCM), against physics‐based ...

Effects of Recurving Western North Pacific Tropical Cyclones on Downstream Ridges Over Pacific‐Western North America

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Recurving tropical cyclones (TC) in the Western North Pacific can affect the atmospheric circulation over Pacific‐Western North America (PWNA) via interactions with the midlatitude circulation. Using reanalysis and tropical cyclone best‐track data, we examine how recurving TCs that make extratropical transition modulate 500‐hPa ridge ...

Tropical Cyclones Drive Enhanced Inorganic Iodine in the Mid‐Latitude Upper Troposphere

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Halogens deplete tropospheric and stratospheric ozone, but the role of iodine is still elusive. Atmospheric iodine mainly originates from marine inorganic (I2, HOI) and organic (CH3I, CH2I2, CH2IBr, and CH2ICl) emissions. We report on airborne measurements of atmospheric iodine oxide (IO) concentrations up to 15 km altitude from two flights of

Weather Regimes Preclude the Observation of a Southern Annular Mode Signal in Two Coastal East Antarctic Ice Cores

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract The Southern Annular Mode (SAM) represents the dominant pattern of climate variability in the extratropical Southern Hemisphere. However, its signature in coastal East Antarctic ice core records is unclear. A daily synoptic typing data set for the southern Indian Ocean constructed using self‐organizing maps on 500 hPa daily geopotential height

Linking Salinity and Precipitation Through Moisture Transport: A Study for the North Atlantic

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Sea surface salinity (SSS) is a key indicator of the ocean–atmosphere freshwater balance and plays a central role in global moisture transport. This study investigates how extreme SSS anomalies in the North Atlantic (NATL) source region indicate atmospheric moisture pathways and precipitation in surrounding continental and island sink regions.

Historical Trends in Cold‐Season Mid‐Latitude Cyclones in the Great Lakes Region

Geophysical Research Letters
The Great Lakes Region (GLR) of North America is at the intersection of multiple extratropical cyclone (ETC) tracks, and the region's cold‐season climate is heavily influenced by the large temperature gradients and intense precipitation associated with ...
