High‐ and Low‐Latitude Insolation Forcing Drives the Half‐Precession Cycle in Winter Arctic Sea Ice

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The half‐precession cycle is a key climatic signal in global climate system, linking high‐ and low‐latitude climate variability and bridging orbital‐ and millennial‐scale climate changes. While it characterizes tropical insolation, its origin in high‐latitude climate records remains unclear. Based on a transient climate simulation spanning the

Diminished Radiative Cooling With Northward Wildfire Advance in the East Siberian Boreal Region

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Intensification of the Siberian wildfire regime is characterized by large increases in burned area above the Arctic Circle. Wildfire in boreal forests typically reduces albedo in the decades following fire, resulting in a net cooling effect. Here we quantified changes in albedo and the accompanying radiative forcing associated with a northward

Effects of Mineralogical Inhomogeneity on Aggregate Dust Optical Properties and Lidar Observables

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Dust aerosols comprise irregular grains and aggregates with various mineralogical mixtures. However, most optical models use effective refractive indices to represent particles. This study develops an inhomogeneous aggregate model assigning mineral‐dependent refractive indices to constituent elements and representing global mineral volume ...

Why April Stands Out: Monthly Impacts of Internal Variability on Arctic Amplification

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Observed Arctic amplification (AA), defined as the ratio of Arctic‐mean to global‐mean surface air temperature (SAT) trends, peaks in April, a feature not captured by climate models. Here, we quantify the impact of internal variability on Arctic‐mean SAT trends in March, April, and May from 1980 to 2022 using multiple approaches, including ...
