A Satellite‐Based Estimate of the Contribution of Filamentary Structures to Lateral Carbon Transport in the Pacific and Atlantic Upwelling Systems

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Cross‐shelf interactions and the associated lateral transport of organic carbon remain poorly quantified and constrained by observations, despite their importance for the ocean carbon cycle. Filaments generated by instabilities of coastal currents are one pathway for this exchange, but their transport is difficult to observe at basin scales ...

New Constraints on the Onset of Antarctic Glaciation From Combined Radiogenic Hafnium and Neodymium Isotopes

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The drawdown of atmospheric CO2 likely triggered Antarctic glaciation during the Eocene‐Oligocene Transition (34 Ma). Accurately constraining this shift from “greenhouse” to an “icehouse” climate is essential for understanding global carbon cycle dynamics.

Significant Aqueous‐Phase Processing of Secondary Aerosols Associated With South Asian Outflow in the Water Vapor Channel of the Southeastern Tibetan Plateau

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Ambient aerosols exert growing influences on atmospheric radiative forcing, precipitation, and climate change over the Tibetan Plateau (TP), yet observational constraints on their chemical characteristics remain sparse in this high‐altitude region.

Stratospheric Quasi‐Biennial Oscillation Modulates Tropical Cyclone Extreme Rainfall Over East Asia via Intraseasonal Oscillation

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Tropical cyclone (TC)‐induced extreme precipitation (TCEP) poses heavy risks, yet its seasonal predictability remains limited by insufficient understanding of cross‐scale climatic drivers. Here, we elucidate a stratosphere‐to‐stratosphere coupling pathway where the quasi‐biennial oscillation (QBO) modulates TC activity and subsequent TCEP over

Horizontal and Vertical Structure of Cloud Effective Radius in Eastward‐Propagating Convective Systems

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Organized convective systems produce a disproportionate fraction of warm‐season rainfall, yet satellite‐based analyses generally neglect propagation‐relative microphysical organization. We develop a propagation‐relative partitioning framework using FY‐4A geostationary satellite observations to characterize sector‐resolved cloud effective ...
