Moisture Dynamics with Phase Changes in a Compressible Hydrostatic Atmosphere

Lin Ma, Tarek Zöchling

In this article, a rigorous well-posedness result is established for a moist compressible primitive-equation system with phase changes. The model couples the compressible primitive…

Continuous Data Assimilation for Semilinear Parabolic Equations with Multiplicative Observation Noise

Jochen Bröcker, Gianmarco Del Sarto, Matthias Hieber +2

The problem of continuous data assimilation for semilinear parabolic equations based on partial observations corrupted by noise is investigated. The noise is allowed to be multipli…

Noise-Driven Free Boundaries In The Compressible Navier-Stokes Equations

Gianmarco Del Sarto, Matthias Hieber, Tarek Zöchling

A stochastic free-boundary problem for the three-dimensional barotropic compressible Navier--Stokes equations is studied. The main feature of the model is that the free boundary is…

Global Strong Well-posedness of the heat-conducting, compressible primitive Equations

Tarek Zöchling

The full heat-conducting compressible primitive equations are considered, extending the compressible primitive-equation framework by coupling the temperature through the ideal gas…

Continuous Data Assimilation for Semilinear Parabolic Equations: A General Approach by Evolution Equations

Gianmarco Del Sarto, Matthias Hieber, Filippo Palma +1

This article develops a general framework for continuous deterministic data assimilation for semilinear parabolic equations by means of evolution equations. Introducing a nudged mo…

Moisture dynamics with phase changes coupled to heat-conducting, compressible fluids

Felix Brandt, Matthias Hieber, Lin Ma +1

It is shown that a model coupling the heat-conducting compressible Navier-Stokes equations to a micro-physics model of moisture in air is locally strongly well-posed for large data…
