Structural Compactness of North Atlantic Tropical Cyclone Seeds in Historical and Projected Climates

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We examine how the structural compactness of North Atlantic tropical cyclone (TC) seeds responds to warming in ERA5 reanalysis and CAM5 simulations. In ERA5, comparing 1985–1999 with 2000–2014, developing seeds in the later, warmer period become slightly more compact and exhibit stronger mid‐level ascent and low‐level convergence, whereas non ...

ENSO's Imprint on the Southern Ocean: Wind Waves Drive Surface Cross‐Frontal Flow

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Tropical teleconnection associated with El Niño–Southern Oscillation (ENSO) is widely recognized for regulating multiple physical processes in the Southern Ocean. However, despite its influence on Southern Ocean wind patterns, the response of surface flow has received little attention.

A Shift of Multidecadal Trend in Coastal Upwelling Off Southern Vietnam in the South China Sea Around 1999

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract To explore multidecadal trends of the Vietnamese Southern Coastal Upwelling (SCU), we employed an SCU index (Southern Coastal Upwelling index [SCUI]), defined as the difference between basin‐wide SST (Tref ${T}_{\mathrm{r}\mathrm{e}\mathrm{f}}$) and local minimum SST (Tmin ${T}_{\min }$).

Does El Nino Affect Business Cycles [PDF]

In this paper we test to see if the El Niño-Southern Oscillation (ENSO) phenomenon has an influence on national business cycles. If El Niño has any effect at all on business cycles and economic growth, one would expect it, at the very least, to affect ...

Tidal Variability in the Lower Thermosphere: Relative Importance of ENSO, QBO, PJO, MJO, and Lyα

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric tides in the lower thermosphere play an important role in regulating upper‐atmospheric conditions relevant to space weather. However, their spatial and temporal variability remains poorly understood, apart from seasonal variations. Previous studies have shown that tides can be influenced by meteorological and solar conditions. This

Classification of Summer Extratropical Cyclones Over Northeast China and Their Impacts on Regional Precipitation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Based on the ERA5 six‐hourly reanalysis data set and objective identification and tracking methods for extratropical cyclones (ECs), this study identified 423 summer ECs that passed through Northeast China (NEC) during 1979–2023. These ECs were categorized into three distinct types using K‐means clustering based on their genesis locations.

Daily Peak Activity of the African Lightning Chimney Based on Meteosat Third Generation (MTG) Lightning Imager (LI), World Wide Lightning Location Network (WWLLN), and Schumann Resonance (SR) Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Lightning activity is strongly concentrated in tropical continental “chimneys”, among which the African lightning chimney stands out as the most intense globally. However, until recently, the incomplete and spatially uneven detection efficiency of ground‐based lightning networks, together with the limited spatio‐temporal coverage of satellite ...

Divergent Influences of Oceanic Western Boundary Currents on Weak and Strong Tropical Cyclones

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Tropical cyclones (TCs) in the Northern Hemisphere often cross oceanic western boundary currents (WBCs), yet how these warm currents modulate TC intensity remains unclear. We analyze TCs traversing the Kuroshio and Gulf Stream during 1993–2025 and find that weak TCs respond more favorably than strong TCs.

Differential Impacts of Proxy Archives on Paleoclimate Reconstruction Performance

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Reconstructing past climates is challenging because pre‐instrumental observations are geographically sparse and proxy records are noisy; data assimilation offers one approach to address these limitations. Although such reconstructions are now widespread, the extent to which different proxy archives determine their accuracy remains unclear.
