Anomalous Energy Fluxes and Feedback Parameter Over the Course of ENSO Events

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Internal variability may provide constraints on the global temperature response to forcing. Previous work showed that ENSO induces atmospheric stratification anomalies that lead to tropical low cloud anomalies not correlated with mean temperature. Here, we expand this argument. We discuss the physical processes leading to a canonical evolution

Pattern Recognition of West African Monsoon Extreme Rainfall Events Using Convolutional Neural Networks

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Accurate prediction of extreme rainfall and dry events remains a major challenge in West Africa due to the complex and non‐linear dynamics of the monsoon system, which involve interactions among local convection, large‐scale circulation, ocean‐atmosphere coupling, and intra‐seasonal variations.

Multi‐LiDAR Observations of Coastal Atmospheric Duct Evolution in Hampton Roads

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract To better understand the influence of atmospheric ducts on radio frequency (RF) operations, continuous high‐resolution observations of temperature and water vapor are essential. Hampton University's (HU) 48‐inch Raman‐Mie LiDAR provides such measurements through rotational and vibrational Raman techniques, enabling detailed monitoring of ...

MSWD: A Hybrid Machine‐Learning Framework for Slant Wet Delay Modeling

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Space geodetic techniques such as Global Navigation Satellite Systems (GNSS) and Very Long Baseline Interferometry (VLBI) are limited by direction‐dependent tropospheric delays, with slant wet delay (SWD) being the most variable component and a major error source.

GNSS Zenith Wet Delay as a Boundary Layer Diagnostic: Regime‐Dependent Turbulence Signatures From Large Eddy Simulation and Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Global Navigation Satellite Systems (GNSS) provide continuous measurements of zenith wet delay (ZWD), reflecting column‐integrated atmospheric water vapor. While the slowly varying ZWD is routinely assimilated in numerical weather prediction, the rapid fluctuations on timescales of seconds to minutes that arise from boundary‐layer turbulence ...
