Replacing Tunable Parameters in Weather and Climate Models With State‐Dependent Functions Using Reinforcement Learning

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Weather and climate models rely on parameterizations to represent unresolved sub‐grid processes. Traditional schemes rely on fixed coefficients that are weakly constrained and tuned offline, contributing to persistent biases that limit their ability to adapt to underlying physics.

What Drives Precipitation Intensification During Zonal Atmospheric Rivers Landfalling in the Extratropical Andes?

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The extratropical Andes, a hotspot for landfalling atmospheric rivers (ARs), are prone to extreme precipitation and related hydrological hazards, including floods and landslides. An improved understanding of the drivers of precipitation intensification during AR landfall is critical for hazard preparedness. Focusing on 50 zonally elongated ARs

Subseasonal Tropical Convection Characteristics in the Energy Exascale Earth System Model Version 2

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Accurate simulation of subseasonal tropical moist convection remains a key challenge for Earth system models. The difficulties stem from the reliance of cumulus cloud processes on model parameterizations and the need to represent the multiscale nature of interactions among clouds, radiation, moisture, circulation, and surface energy fluxes ...

On the Tropical Nature of an Intense Mediterranean Cyclone in the Ocean‐Atmosphere System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The Mediterranean basin hosts a large number of cyclones every year. Among them, some rare cases named medicanes present similarities with tropical cyclones but their dynamical characteristics are debated. The ocean‐atmosphere dynamics of Medicane Ianos (2020) are studied here through km‐scale fully coupled ocean‐wave‐atmosphere simulations ...

Influence of Model Resolution on Simulated Extreme Wildfire Plume Heights During the 2019/2020 Australian New Year Event

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Pyrocumulonimbus (pyroCb) events, smoke‐infused thunderstorm clouds triggered by intense wildfires under suitable meteorological conditions, are an efficient pathway for transporting smoke to elevated altitudes. In some cases, smoke reaches the upper troposphere and lower stratosphere region, where it can persist for extended time periods and ...

Ecohydrologic Processes Modify Urban Rainfall Intensification in Land‐Atmosphere Simulations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Ecohydrologic processes influence urban water and energy cycles including convective rainfall. Coupled land‐atmosphere models, however, lack fine‐scale representation of urban ecohydrology processes. This study integrates these processes into ensemble land‐atmosphere simulations to assess changes in convective rainfall in Milwaukee, Wisconsin.

From Shadow to Fertilizer: Slanted Sunlight in 3D Radiation Enhances Cloud Condensate, Size, and Lifetime of Shallow Cumulus

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The impact of three‐dimensional (3D) shortwave radiation on cloud condensate, size and lifetime is investigated using large‐eddy simulations coupled to an interactive land surface model (LSM). Results show 3D radiation produces higher cloud tops and greater cloud condensate than 1D radiation, resulting from larger downward shortwave fluxes ...
