Machine Learning‐Based Analysis of Atmospheric Process Sensitivity to Land Surface Properties Over Complex Terrain

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract This study investigates the sensitivity of numerical simulations of atmospheric processes over complex terrain to land surface model (LSM) parameters, focusing on thermally driven circulations in an idealized valley. The sensitivity analysis is performed using the Weather Research and Forecasting model coupled with the Noah‐MP LSM, for forest ...

Lightning Outbreaks at the Mature Stage of Tropical Cyclone: Case Study for Hurricane Dorian (2019)

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The relationship between tropical cyclone (TC) lightning activity and intensity change has been examined for nearly 30 years, yet a clear consensus remains elusive, reflecting the complexity of the processes governing TC lightning. This study investigates the physical mechanisms that triggered inner‐core lightning outbreaks during the mature ...

Pseudo‐Radar Reflectivity by Applying U‐Net Models to Global Passive Microwave Brightness Temperatures

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Spaceborne radar systems such as the Global Precipitation Measurement Mission (GPM)'s core satellite Dual‐frequency Precipitation Radar (DPR) provide global insight into precipitation structure, storm morphology, and hydrological cycles. However, their limited spatial and temporal sampling and high cost constrain their ability to continuously ...

Measurement of the Entangled Two‐Photon Absorption Cross‐Sections of 4‐Aminoazobenzene

ChemPhysChem, Volume 27, Issue 9, 14 May 2026.
Using 4‐aminoazobenzene with extremely low one‐photon attenuation in the EP band, we isolated entangled two‐photon absorption from linear loss by separating correlated and uncorrelated photon counts. The resulting σE is ≈1018 larger than δ(2) (at ≈108 photons·s–1·cm–2), while remaining ≈107 smaller than δ(1).

Spectropolarimetric Holographic Multiplexing Metasurface With Super‐High Capacity Empowered by Mechanical Rotation

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Mechanically reconfigurable metasurfaces enable high‐capacity optical storage and holography due to low cost/complexity. A differentiable inverse design framework maps meta‐atom geometries to multichannel optical responses via deep neural networks. Rotatable cascaded metasurfaces optimized through this pipeline achieve pixel‐level holography with 288 ...
