A First Look at the Global Climatology of Low‐Level Clouds in Storm Resolving Models

Journal of Advances in Modeling Earth Systems
The representation of subtropical stratocumulus and trade‐wind cumulus clouds by preliminary versions of Integrated Forecasting System (IFS) and ICON km‐scale global coupled climate models is explored.

The Response of Cloud Dynamic Structure and Microphysical Processes to Glaciogenic Seeding: A Numerical Study

Atmosphere
Stratocumulus clouds are cloud systems composed of stratiform clouds with embedded convective clouds, possessing strong catalytic potential and serving as key target cloud systems for weather modification operations.

Turbulence Structure in a Stratocumulus Cloud [PDF]

Atmosphere, 2018
The growth of computing power combined with advances in modeling methods can yield high-fidelity simulations establishing numerical simulation as a key tool for discovery in the atmospheric sciences. A fine-scale large-eddy simulation (LES) utilizing 1.25 m grid resolution and 5.12 × 5.12 km 2 horizontal domain is used to investigate the ...

Coral δ13C Reveals Little Ice Age Dimming of Tropical Surface Shortwave Radiation Not Captured by Climate Models

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Tropical low‐cloud feedback is the largest source of uncertainty in climate sensitivity, yet multi‐century records of surface shortwave radiation are scarce. We calibrate Porites coral δ13C against satellite photosynthetically available radiation (PAR) and reconstruct monthly PAR for the northern South China Sea during the Medieval Climate ...

A Dynamical Model for the Shallow‐to‐Deep Transition of Amazonian Moist Atmospheric Convection

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The development of deep convection and the timing of storm convection initiation over land are generally poorly represented by weather and climate models, probably due to the poor representation of the interaction between shallow and deep convection.

An Emulator of Stratocumulus Cloud Response to Two Cloud‐Controlling Factors Accounting for Internal Variability

Journal of Advances in Modeling Earth Systems
Large uncertainties persist in modeling shallow, low clouds because of many interacting nonlinear processes and multiple cloud‐controlling environmental factors. In addition, sharp changes in behavior occur when environmental thresholds are met.

Impact on the stratocumulus-to-cumulus transition of the interaction of cloud microphysics and macrophysics with large-scale circulation [PDF]

Atmospheric Chemistry and Physics
This study examines the impact of the interaction of cloud microphysics and macrophysics with the large-scale circulation on the stratocumulus-to-cumulus transition (SCT) using a large-eddy simulation (LES) combined with weak-temperature-gradient (WTG ...

Formulations of moist thermodynamics for atmospheric modelling

, 2015
Internal energy, enthalpy and entropy are the key quantities to study thermodynamic properties of the moist atmosphere, because they correspond to the First (internal energy and enthalpy) and Second (entropy) Laws of thermodynamics.

Diverse Cloud Regimes in the Northeast Pacific: Evaluating a Mesoscale NWP Model With Shipborne Observations

Meteorological Applications, Volume 33, Issue 2, March/April 2026.
Weather prediction and climate models need to simulate clouds of a variety of types. Here we evaluate how well a near‐operational version of such a model simulates clouds in the northeastern Pacific Ocean region. Aspects of the model, including the vertical and horizontal grid spacing and internal formulation, affect the results, and the model errors ...
