Gamma‐Ray Glows Commonly Followed by Lightning: A Statistical Study of the Spatio‐Temporal Relationship

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Gamma‐ray glows are prolonged enhancements of gamma rays from thunderclouds, which are often linked to large‐scale electric fields rather than individual lightning. The link between glows and lightning remains poorly understood. Here, we analyzed 300 glows observed during the ALOFT aircraft campaign and optical lightning detected by GLM.

Coherent Turbulence Signatures Preceding Warm Rain Events From Collocated Cloud Radar and Wind Profiler Observations Across China

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Warm rain is plagued by a longstanding droplet growth bottleneck, one that turbulence may alleviate by enhancing droplet coalescence in the late condensation phase. Nevertheless, empirical observational support from multiple sites remains scarce. Here, we combine collocated nationwide millimeter cloud radars, radar wind profilers, Himawari‐8/9

Performance of high-resolution X-band radar for rainfall measurement in The Netherlands [PDF]

, 2010
This study presents an analysis of 195 rainfall events gathered with the X-band weather radar SOLIDAR and a tipping bucket rain gauge network near Delft, The Netherlands, between May 1993 and April 1994.

Contrasting Effects of Turbulence on Tropical Cyclones During Landfall

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Planetary boundary layer (PBL) turbulence modulates tropical cyclone (TC) intensity through competing mechanisms: (a) frictional dissipation that weakens TCs and (b) frictional convergence that drives stronger low‐level inflow and intensifies TCs.

Airborne laser scan data: a valuable tool with which to infer weather radar partial beam blockage in urban environments [PDF]

Atmospheric Measurement Techniques, 2016
High-spatial-resolution weather radar observations are of primary relevance for hydrological applications in urban areas. However, when weather radars are located within metropolitan areas, partial beam blockages and clutter by buildings can seriously ...

Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.

Flight of the dragons: a global review of migration in Odonata

Biological Reviews, Volume 101, Issue 5, Page 2134-2157, October 2026.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.
