Atmospheric ice nucleation is crucial for global precipitation and affects the structure, lifetime
and reflectivity of clouds, thereby impacting climate. Ice nucleates in various ways from …

The cloud droplet number concentration (N d) is of central interest to improve the
understanding of cloud physics and for quantifying the effective radiative forcing by aerosol …

Predicting the formation of ice in the atmosphere presents one of the great challenges in
physical sciences with important implications for the chemistry and composition of the …

Most atmospheric motions of different spatial scales and precipitation are closely related to
phase transitions in clouds. The continuously increasing resolution of large‐scale and …

Mixed-phase clouds represent a three-phase colloidal system consisting of water vapor, ice
particles, and coexisting supercooled liquid droplets. Mixed-phase clouds are ubiquitous in …

Abstract Number concentrations of ice-nucleating particles (N INP) in the Arctic were derived
from ground-based filter samples. Examined samples had been collected in Alert (Nunavut …

Ice nucleating particles (INPs) affect the radiative properties of cold clouds. Knowledge
concerning their concentration above ground level and their potential sources is scarce …

One of the most intense air mass transformations on Earth happens when cold air flows from
frozen surfaces to much warmer open water in cold-air outbreaks (CAOs), a process …

We perform a model intercomparison of summertime high Arctic (> 80∘ N) clouds observed
during the 2008 Arctic Summer Cloud Ocean Study (ASCOS) campaign, when observed …

Pulses of warm and moist air from lower latitudes provide energy to the Arctic and form its
main energy source outside of the summer months. These pulses can cause substantial …
