CYCLOP Revegoca: The First Documented Cyclone Formed From Locally Originating Potential Intensity Over the Southwestern South Atlantic

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract On 9 December 2025, an atypical synoptic cyclone developed near the borders of Paraguay, Argentina, and southern Brazil, triggering severe weather across south‐southeastern Brazil. Unlike typical South Atlantic extratropical cyclones, which intensify near the coast, this system originated inland and underwent explosive cyclogenesis without a ...

The Predictability of the Downward Versus Non‐Downward Propagation of Sudden Stratospheric Warmings in S2S Hindcasts

Geophysical Research Letters
Roughly one‐third of sudden stratospheric warming (SSW) events lack a strong canonical surface response, and this can lead to a forecast bust if a strong response was predicted.

Stratosphere–Troposphere Coupling During Cold Air Outbreaks in the Eastern United States

Geophysical Research Letters
Cold air outbreaks (CAOs) are extreme weather events characterized by the equatorward displacement of polar air. This study investigates CAOs occurring along the East Coast of the US and establishes that approximately 16% are driven by stratosphere ...

Potential contribution of stratosphere–troposphere coupling to Pacific decadal oscillation teleconnection to Antarctic summer sea ice melt

npj Climate and Atmospheric Science
Antarctic sea ice expanded pre–20151–3 and declined rapidly post–20154, a regime shift generally attributed to a combination of factors, including sudden Southern Annular Mode transition5 and tropospheric teleconnections associated with the Pacific4,6–8.

A dataset of Beijing MST radar horizontal wind fields at Xianghe Station in 2012

中国科学数据
The atmospheric horizontal wind is an essential parameter for studying atmospheric dynamic characteristics, processes, and dynamic coupling between the upper and lower atmosphere. MST (Mesosphere Stratosphere and Troposphere) radar plays a unique role in

Changing Influence of East Asian Jet Shift on Heatwave in China: Role of Arctic Newly Formed Ice

Ocean-Land-Atmosphere Research
The Arctic is transitioning from a multiyear to newly formed ice (NFI)-dominated regime; however, the cross-seasonal impacts on the East Asian mid-latitude climate remain unclear.

Benchmarking the Dynamic Modes of Stratosphere‐Troposphere Coupling in Northern Annular Modes (NAM) in CMIP6 Models

Geophysical Research Letters
The downward influence of extreme stratospheric events is typically described by the evolution of the Northern Annular Mode (NAM) across atmospheric levels. However, the dynamics and uncertainty in vertical coupling are not fully resolved.

Preconditioned Stratospheric Modulation on the Occurrence of Stratospheric Final Warmings

Geophysical Research Letters
Stratospheric Final Warmings (SFWs) are considered to have a distinct impact on the surface weather and stratospheric ozone. Most SFWs are predominantly wave‐driven, while previous studies generally focused on the effects of tropospheric anomalous wave ...
