Deposition freezing, pore condensation freezing and adsorption: three processes, one description?

Heterogeneous ice nucleation impacts the hydrological cycle and climate through affecting cloud microphysical state and radiative properties. Despite decades of research, a quantitative description and understanding of heterogeneous ice nucleation remains ...

Role of K-feldspar and quartz in global ice nucleation by mineral dust in mixed-phase clouds

Athanasios Nenes

Ice-nucleating particles (INPs) enable ice formation, profoundly affecting the microphysical and radiative properties, lifetimes, and precipitation rates of clouds. Mineral dust emitted from arid regions, particularly potassium-containing feldspar (K-felds ...

Snow Loss Into Leads in Arctic Sea Ice: Minimal in Typical Wintertime Conditions, but High During a Warm and Windy Snowfall Event

Julia Schmale, Marc Schneebeli Zeugin, Markus Frey

The amount of snow on Arctic sea ice impacts the ice mass budget. Wind redistribution of snow into open water in leads is hypothesized to cause significant wintertime snow loss. However, there are no direct measurements of snow loss into Arctic leads. We m ...

RaFSIP: Parameterizing ice multiplication in models using a machine learning approach

Athanasios Nenes, Paraskevi Georgakaki

Representing single or multi-layered mixed-phase clouds (MPCs) accurately in global climate models (GCMs) is critical for capturing climate sensitivity and Arctic amplification. Ice multiplication, or secondary ice production (SIP), can increase the ice cr ...

Sources and seasonality of fluorescent aerosols in the Arctic

Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Nora Bergner, Alireza Moallemi

Aerosol‐cloud interactions play an important role in the Arctic climate but remain poorly understood. Ice nucleating particles (INPs) contribute to the formation of ice crystals at temperatures above ‐38 °C in mixed phase clouds, which are predominant in t ...

Characteristic rupture height of the mediating air film beneath an impacting drop on atomically smooth mica

John Martin Kolinski, Ramin Kaviani

Before a droplet can contact a surface during impact, it must first displace the air beneath it. Over a wide range of impact velocities, the droplet first squeezes the air into a thin film, enhancing its resistance to drainage; this slows the progress of t ...

A full year of aerosol size distribution data from the central Arctic under an extreme positive Arctic Oscillation: insights from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition

Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Hélène Paule Angot, Lubna Dada, Federico Bianchi

The Arctic environment is rapidly changing due to accelerated warming in the region. The warming trend is driving a decline in sea ice extent, which thereby enhances feedback loops in the surface energy budget in the Arctic. Arctic aerosols play an importa ...

Towards continuous measurements of snow drift and sublimation in polar environments

Michael Lehning, Wolf Hendrik Huwald, John Martin Kolinski, Yael Frischholz, Armin Sigmund, Balthazar Allegri

In polar regions, and specifically in continental Antarctica, the local surface mass and energy balances can be largely controlled by snow transport in form of drifting and blowing snow particles, and sublimation both from the snow or ice surface and from ...

Thermal Conductivity of Snow on Arctic Sea Ice

Henning Löwe, Marc Schneebeli Zeugin, David Nicholas Wagner

Snow significantly impacts the seasonal growth of Arctic sea ice due to its thermally insulating properties. Various measurements and parametrizations of thermal properties exist, but an assessment of the entire seasonal evolution of thermal conductivity a ...
