Ice clouds as nonlinear oscillators
Hannah Bergner, Peter Spichtinger
Clouds are important features of the atmosphere, determining the energy budget by interacting with incoming solar radiation and outgoing thermal radiation, respectively. For pure i…
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…
Northlight: Declarative and Optimized Analysis of Atmospheric Datasets in SparkSQL
Justus Henneberg, Felix Schuhknecht, Philipp Reutter +2
Performing data-intensive analytics is an essential part of modern Earth science. As such, research in atmospheric physics and meteorology frequently requires the processing of ver…
Pattern formation in clouds via Turing instabilities
Juliane Rosemeier, Peter Spichtinger
Pattern formation in clouds is a well-known feature, which can be observed almost every day. However, the guiding processes for structure formation are mostly unknown, and also the…
Reflection and transmission of gravity waves at non-uniform stratification layers
Christopher Pütz, Mark Schlutow, Rupert Klein +2
The present study focuses on the interaction of gravity waves in the atmosphere with the tropopause. As the vertical extent of the latter is small compared to the density scale hei…
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…
Stochastic Galerkin method for cloud simulation
A. Chertock, A. Kurganov, M. Lukáčová-Medviďová +2
We develop a stochastic Galerkin method for a coupled Navier-Stokes-cloud system that models dynamics of warm clouds. Our goal is to explicitly describe the evolution of uncertaint…
