Open AccessAnthropogenic aerosol and cryosphere changes drive Earth’s strong but transient clear-sky hemispheric albedo asymmetry
A striking feature of the Earth system is that the Northern and Southern Hemispheres reflect identical amounts of sunlight. This hemispheric albedo symmetry comprises two asymmetries: The Northern Hemisphere i...

Open AccessThe Radiative Forcing of Aerosol–Cloud Interactions in Liquid Clouds: Wrestling and Embracing Uncertainty
This article discusses some of the challenges that have limited progress in quantifying the radiative forcing associated with aerosol–cloud interactions (ACI) in warm (liquid-water) clouds. It reviews recent p...

Detection limits of albedo changes induced by climate engineering
Geoengineering the climate by increasing the Earth's reflectivity has been suggested. In this Perspective, the detectability of various methods is investigated. Although satellite observations can detect large...

Open AccessAdaptive behavior of marine cellular clouds
Shallow marine clouds appear in two formations - open cells that are weakly reflective and closed cells that are more reflective and hence more effective at cooling the climate system. Lagrangian satellite dat...

Climate Processes: Clouds, Aerosols and Dynamics
Physical processes not well resolved by climate models continue to limit confidence in detailed predictions of climate change. The representation of cloud and convection-related processes dominates the model s...

Aerosol-induced intensification of rain from the tropics to the mid-latitudes
Atmospheric aerosols affect cloud properties, and thereby the radiative balance of the planet and the water cycle. An analysis of satellite data suggests that increases in aerosol abundance are associated with...

Resilience of persistent Arctic mixed-phase clouds
Mixed-phase clouds, comprising both ice and supercooled liquid water, have a large impact on radiative fluxes in the Arctic. Interactions between numerous local feedbacks sustain these complex cloud systems, l...

Precipitation-generated oscillations in open cellular cloud fields
Cloud simulation is one of the most challenging tasks in regional- to global-scale climate modelling. In many cases, the physical mechanisms responsible for observed cloud dynamics are unknown, making it diffi...

Untangling aerosol effects on clouds and precipitation in a buffered system
Atmospheric aerosol particles are crucial to the existence of clouds as we know them. It is thought that the aerosol can affect the ability of clouds to form precipitation and in turn cloudiness. But how, in d...

Effects of Pollution Aerosol and Biomass Burning on Clouds and Precipitation: Numerical Modeling Studies
The history of numerical modeling of the effect of aerosols on clouds dates back at least 50 years to the work of Howell (1949) and Mordy (1959), who considered the growth of a population of aerosol particles ...
