Interactions between gravity waves and cirrus clouds: asymptotic modeling of wave induced ice nucleation
Stamen I. Dolaptchiev, Peter Spichtinger, Manuel Baumgartner +1
We present an asymptotic approach for the systematic investigation of the effect of gravity waves (GW) on ice clouds formed through homogeneous nucleation. In particular, we consid…
On numerical broadening of particle size spectra: a condensational growth study using PyMPDATA
Michael Olesik, Jakub Banaśkiewicz, Piotr Bartman +3
This work discusses the numerical aspects of representing the diffusional (condensational) growth in particulate systems such as atmospheric clouds. It focuses on the Eulerian mode…
A model for warm clouds with implicit droplet activation, avoiding saturation adjustment
Nikolas Porz, Martin Hanke, Manuel Baumgartner +1
The representation of cloud processes in weather and climate models is crucial for their feedback on atmospheric flows. Since there is no general macroscopic theory of clouds, the…
Intercomparison of Warm-Rain Bulk Microphysics Schemes using Asymptotics
Juliane Rosemeier, Manuel Baumgartner, Peter Spichtinger
Clouds are important components of the atmosphere. Since it is usually not possible to treat them as ensembles of huge numbers of particles, parameterizations on the basis of avera…
