Wildfire Ignition‐Day Vapor Pressure Deficit Trend and Its Weakening Atmospheric Circulation Control Over the Western United States

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Vapor pressure deficit (VPD) is a key fire weather indicator linked to increased burned areas in western US. Despite a strong increase in regional VPD due to climate change, we find no significant trend in VPD on fire ignition days (VPDF). This discrepancy is due to a decreasing climatological mean (VPDF‐m), driven by the expansion of fires ...

Remote Forcing of Super Typhoon Mawar on the 2023 Quebec Wildfires

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Typhoons and wildfires are major global climate and environmental hazards, yet their potential interactions remain poorly understood, particularly through remote atmospheric forcing. Taking the 2023 Quebec wildfires as an example, we investigate how a tropical cyclone can influence wildfire‐favorable conditions.

First Observations and Characteristics of Positive Upward Illumination Strokes

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Upward Illumination (UI) strokes are a subtype of cloud‐to‐ground (CG) return strokes characterized by two concurrent branches striking the ground a few milliseconds apart. The luminous channel of an UI stroke does not connect to the main channel, which gives this phenomenon its name.

In Situ Observations of Ice Crystal Chain Aggregates in Winter Storms

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ice crystal chain aggregates—linear structures of conjoined monomer crystals—have previously been observed in strongly electrified deep convection, likely forming via electric‐field‐enhanced aggregation. The NASA Investigation of Microphysics and Precipitation for Atlantic Coast‐Threatening Snowstorms field campaign conducted aircraft‐based ...
