Effects of solid aerosols on partially glaciated clouds

Abstract: Sensitivity tests were conducted using a state‐of‐the‐art aerosol–cloud to investigate the key microphysical and dynamical mechanisms by which solid aerosols affect glaciated clouds. The tests involved simulations of two contrasting cases of deep convection—a tropical maritime case and a midlatitude continental case, in which solid aerosol concentrations were increased from their pre‐industrial (1850) to their present‐day (2010) levels. In the midlatitude continental case, the boosting of the number concentrat… Show more

“…Ice nucleating particles (INPs) can initiate heterogeneous nucleation of ice within cloud droplets at temperatures warmer than those required for homogeneous nucleation. As a result, INPs can influence the radiative properties and lifetime of clouds, as well as climate and the hydrological cycle. The modes of heterogeneous nucleation include deposition nucleation, pore-condensation freezing, contact freezing, and immersion freezing. , The immersion freezing mode refers to the freezing initiated by INPs immersed in liquid droplets. This mode is the most relevant for ice formation in mixed-phase clouds , and is the focus of this study.…”

“…The formation of ice in clouds can strongly influence their lifetime and optical properties. Ice forms in clouds by either homogeneous freezing or heterogeneous freezing initiated by a foreign nucleus, also called an ice nucleating particle (INP). Heterogeneous freezing can be classified as deposition freezing, immersion freezing, condensation freezing, contact freezing, or pore condensation freezing. , In this paper, we focus on immersion freezing, which refers to ice nucleation initiated by an INP immersed in a liquid droplet.…”

“…These particles can modify the properties of mixed-phase clouds, including their lifetime and optical properties, by changing the ratio of ice to liquid water in these clouds. [3][4][5][6][7][8] Hence, information on the concentrations, composition, and sources of INPs in the Arctic is critical to predict climate and the hydrological cycle in the region. Furthermore, as temperatures increase in the Arctic, 9,10 the coverage of sea ice and land snow is expected to decrease.…”
