The Liouville Equation in Atmospheric Predictability

  title={The Liouville Equation in Atmospheric Predictability},
  author={M. Ehrendorfer},
It is widely recognized that weather forecasts made with dynamical models of the atmosphere are inherently uncertain. Such uncertainty of forecasts produced with numerical weather prediction (NWP) models arises primarily from two sources: namely, from imperfect knowledge of the initial model conditions and from imperfections in the model formulation itself. The recognition of the potential importance of accurate initial model conditions and an accurate model formulation dates back to times even… Expand
Exploring the limits of ensemble forecasting via solutions of the Liouville equation for realistic geophysical models
This study analyses the morphological characteristics of the time evolution of probability density functions for some low complexity geophysical systems by solving the Liouville equation in order to obtain tractable solutions which are otherwise unfeasible with currently available computational resources.

Uncertainty Dispersion Analysis and Optimal Control of Atmospheric Re-Entry
In this study, the atmospheric re-entry onto Earth and Mars is analysed concerning uncertainties. These uncertainties can arise in the modelling and the initial entry angle and velocity during theExpand
Rethinking the Reynolds Transport Theorem, Liouville Equation, and Perron-Frobenius and Koopman Operators: Spatial and Generalized Parametric Forms
We exploit a lesser-known connection between the (temporal) Reynolds transport theorem, Reynolds averaging and the Liouville equation for the flow of a conserved quantity, to derive new spatial andExpand

Propagation of uncertain inputs through networks of nonlinear components
The propagation of uncertain inputs through series, parallel and feedback interconnections of dynamical systems with simple asymptotic behavior is studied by employing discrete density mapping (analogous to the input-output Perron-Frobenius operator). Expand
