Stratocumulus cloud deepening through entrainment

Tellus A: Dynamic Meteorology and Oceanography, 1984
It is shown that under a fairly wide range of realistic conditions, stratocumulus cloud-top entrainment actually tends to deepen an existing cloud layer, or tends to produce clouds in an unsaturated mixed layer, even though the entrained air is warmer and drier than the mixedlayer air.

Unveiling the Hidden Warming Layer: Metre‐scale Clear‐Sky Radiative Effects at Stratocumulus Cloud Top

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We identify a previously unresolved layer, which we term as the “W‐Layer”, warming at about 2K hr−1 directly above the stratocumulus cloud top using the line‐by‐line radiative transfer model ARTS. The W‐Layer, being only about 5 m thick, poses observational and simulational challenges.

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 ...

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.

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.

Investigating the sign of stratocumulus adjustments to aerosols in the ICON global storm-resolving model [PDF]

Atmospheric Chemistry and Physics
Aerosols can cause brightening of stratocumulus clouds, thereby cooling the climate. Observations and models disagree on the magnitude of this cooling, partly because of the aerosol-induced liquid water path (LWP) adjustment, with climate models ...

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 ...

On the relationship between responses in cloud water and precipitation to changes in aerosol [PDF]

Atmospheric Chemistry and Physics, 2014
Climate models continue to exhibit strong sensitivity to the representation of aerosol effects on cloud reflectance and cloud amount. This paper evaluates a proposed method to constrain modeled cloud liquid water path (LWP) adjustments in response to ...

Airborne Passive Microwave Retrievals of Cloud Liquid Water, Total Precipitable Water, and Near‐Surface Wind Speed in the Maritime Tropics

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract This paper describes improvements to geophysical retrievals from NASA's Advanced Microwave Precipitation Radiometer (AMPR) during the Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex). The retrieved products are validated using independent data sets, and example applications in addressing science questions about the ...
