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.

Modeling the Distribution, Impacts, and Mitigation of Anthropogenic Heat in Los Angeles

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Anthropogenic heat emissions from human energy consumption contribute to the urban heat island (UHI) effect, yet their spatiotemporal distributions and impacts remain uncertain. In this study, we develop a 100 m resolution, hourly anthropogenic heat flux (AHF) data set for Los Angeles County and use the Weather Research and Forecasting model ...

Formation of Shallow Cumulus Patterns Using a Simple Warm Cloud Precipitation Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract A simple model based on predator‐prey‐like dynamics using a system of four nonlinear ordinary differential equations is used to simulate the life cycle of shallow cumulus. By coupling this model across a two‐dimensional array and varying the cloud environment, we can simulate three common patterns of self‐aggregation seen in the maritime ...

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 ...

Large Eddy Simulations of the Atmospheric Boundary Layer Over Satellite‐Sensed Sea Ice Maps

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Surface heterogeneity in the marginal ice zone (MIZ) causes multiscale secondary atmospheric circulations that are challenging to model or observe. The absence or inadequate representation of these circulations in ocean‐atmosphere exchange schemes in climate models is partially responsible for the underestimation of Arctic sea ice loss ...

Mesoscale Soil Moisture Heterogeneity Can Locally Amplify Humid Heat

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Soil moisture is a key ingredient of humid heat through supplying moisture and modifying boundary layer properties. Soil moisture heterogeneity due to for example, antecedent rainfall, can strongly influence weather patterns; yet, its effect on humid heat is poorly understood.

What Is Triggering Ice in Mixed‐Phase Clouds: A Process Analysis With ECHAM6.1‐HAM2.3 Using the Factorial Method

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Mixed‐phase clouds can be found at temperatures between 0 and −38° ${}^{\circ}$C and consist of supercooled cloud droplets and ice crystals. The phase of mixed‐phase clouds is crucial for the radiation budget, which determines the atmosphere's energy balance.

A Path to Improving Simulated Properties of Low Clouds Over the Beaufort Sea Using Airborne in Situ Observations of Subgrid‐Scale Variability

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Arctic low clouds influence Arctic system evolution through their effects on the atmosphere and surface. Unfortunately, atmospheric models and retrospective analysis (reanalysis) struggle to simulate Arctic low cloud occurrence and properties.
