A Deep Learning Model of Lightning Stroke Density

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Lightning plays a crucial role in the Earth's climate system; however, existing parameterizations for use in forecasting and earth system models show room for improvement in capturing spatial and temporal variations in its frequency. This study develops deep learning‐based parameterizations of lightning stroke density using meteorological ...

Unique Vertical Characteristics of Hydrometeors Observed in the Tropical Cyclone Outer Rainband Region

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract This study investigates the vertical cloud microphysics in the stratiform sectors of Hurricane Tammy's outer rainband region and their relationship to local environments. We used in situ Optical Array Probe (OAP) measurements and tail‐Doppler radar data from four NOAA P‐3 spiral modules on 19–22 October 2023, as Tammy intensified from a ...

Decoupling Backward Scattering Control and Forward Beamformed Communication in a Shared‐Aperture Retro‐Reflective/Transmissive Metasurface

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Conceptual illustration of the retro‐reflective and transmissive metasurface (RRTM). The blue radar establishes communication with the UAV via the transmissive mode, whereas the purple surveillance radar acquires the status of friendly units through the retro‐reflective mode and the two modes operate simultaneously within the same decoupled aperture ...
