Atmospheric physics seminar

Immersion freezing: singular vs. time-dependent models

The seminar is online only.

Water droplets containing immersed insoluble surfaces freeze at higher temperatures than that of homogeneous freezing. This process, referred to as immersion freezing, is one of the myriad of phenomena contributing to aerosol-cloud interactions in the atmosphere. Immersion freezing is also crucial for artificial snow production.

Modelling studies addressing immersion freezing embrace either the so-called "singular" or the "time-dependent" description of the process.

In the talk, both approaches will be juxtaposed and presented in the context of particle-based cloud microphysics modelling techniques.
