Distinct Cloud‐to‐Ground Lightning Properties in Frontal Versus Warm‐Sector Heavy Rainfall Events

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Do systematic differences in cloud‐to‐ground (CG) lightning properties—particularly return stroke number and current intensity—exist across different thunderstorm types? This question is foundational not only to the atmospheric electricity but also to advancing lightning risk prediction, which crucially depends on a robust understanding of how

Surfzone Water Depth Estimation From Surface Flows Using a Data‐Driven and Physics‐Informed Deep Conditional Generative Model

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract A physics‐informed deep conditional generative model driven with remotely sensed surface currents is shown to estimate surfzone water depths (bathymetry). The model encodes measured flow data as latent Gaussian parameters and decodes these distributions to estimate water depths over the domain, progressively refining its predictions via a loss‐

Incorporating W‐Band Doppler Velocity Signal Simulator Into COSP2: Model Evaluation Against Ground‐Based Radar Measurement

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract A new signal simulator for Doppler velocity, derived for W‐band cloud profiling radar onboard EarthCARE, is developed and implemented into the Cloud Feedback Model Intercomparison Project Observation Simulator Package version 2 (COSP2). The simulator converts the vertical motion of hydrometeors and cumulus mass flux in global climate models ...

Real Heights of SuperDARN F Region Echoes Inferred From Electron Density Measurements by the Rankin Inlet and RISR‐C Radars

Radio Science, Volume 61, Issue 2, February 2026.
Abstract This study is one of the first attempts to estimate statistically the real height of SuperDARN F region echoes in the polar cap. To achieve this, measurements of the electron density in the scattering volume of the Rankin Inlet SuperDARN radar are compared with the electron density profiles measured by the incoherent scatter radar RISR‐C ...
