Decomposing Cloud Radiative Feedbacks by Cloud-Top Phase [PDF]

Journal of Climate
Changes in cloud scattering properties and emissivity that arise from atmospheric warming cause substantial radiative feedbacks in model projections of anthropogenic climate change, and the relative importance of the underlying mechanisms is poorly understood.

Stellar feedback effects on the mass distribution of clouds and cloud complexes

Astronomy & Astrophysics
Context . Galaxy evolution is sensitive to how stars inject feedback into their surroundings. In particular, the stellar feedback from star clusters strongly affects gas motions and, consequently, the baryonic cycle. More massive clusters have stronger effects.

Mechanisms of marine low cloud sensitivity to idealized climate perturbations: A single‐LES exploration extending the CGILS cases

Journal of Advances in Modeling Earth Systems, 2013
Climate change sensitivities of subtropical cloud‐topped marine boundary layers are analyzed using large‐eddy simulation (LES) of three CGILS cases of well‐mixed stratocumulus, cumulus under stratocumulus, and shallow cumulus cloud regimes, respectively.

Mid-latitude clouds contribute to Arctic amplification via interactions with other climate feedbacks

Environmental Research: Climate
Traditional feedback analyses, which assume that individual climate feedback mechanisms act independently and add linearly, suggest that clouds do not contribute to Arctic amplification.

Climate warming could weaken aerosol-cloud interactions in subtropical marine stratocumulus

npj Climate and Atmospheric Science
Radiative effects of aerosol-cloud interactions constitute the most uncertain climate forcing of the Earth system. To understand how these interactions may change with climate, we conduct 3-day-long large-eddy simulations of a stratocumulus-to-cumulus ...

Coupling between lower‐tropospheric convective mixing and low‐level clouds: Physical mechanisms and dependence on convection scheme

Journal of Advances in Modeling Earth Systems, 2016
Several studies have pointed out the dependence of low‐cloud feedbacks on the strength of the lower‐tropospheric convective mixing. By analyzing a series of single‐column model experiments run by a climate model using two different convective ...

The Single Column Atmosphere Model Version 6 (SCAM6): Not a Scam but a Tool for Model Evaluation and Development

Journal of Advances in Modeling Earth Systems, 2019
The Single Column Atmosphere Model (SCAM) is a single column model version of the Community Atmosphere Model (CAM). Here we describe the functionality and features of SCAM6, available as part of CAM6 in the Community Earth System Model, version 2 (CESM2).

Evaporative Resistance is of Equal Importance as Surface Albedo in High‐Latitude Surface Temperatures Due to Cloud Feedbacks

Geophysical Research Letters, 2020
Arctic vegetation is known to influence Arctic surface temperatures through albedo. However, it is less clear how plant evaporative resistance and albedo independently influence surface climate at high latitudes.

Parametric Sensitivity of Hemispheric Albedo Symmetry Weakly Constrains Shortwave Cloud Radiative Feedbacks in the Community Atmosphere Model Version 6

Geophysical Research Letters
Earth's albedo is symmetric between the northern and southern hemispheres (NH and SH, respectively) because SH clouds compensate for higher NH clear‐sky albedo, a feature that climate models have difficulty capturing.
