The Moon at thermal infrared wavelengths: A benchmark for asteroid thermal models
T. Müller, M. Burgdorf, V. Ali-Lagoa +2
Thermal-infrared measurements of asteroids are crucial for deriving the objects' sizes, albedos, and also the thermophysical properties of the surface material. Depending on the av…
A Large Deviation Theory-based Analysis of Heat Waves and Cold Spells in a Simplified Model of the General Circulation of the Atmosphere
Vera Melinda Galfi, Valerio Lucarini, Jeroen Wouters
We study temporally persistent and spatially extended extreme events of temperature anomalies, i.e. heat waves and cold spells, using large deviation theory. To this end, we consid…
A Statistical Mechanical Approach for the Parametrization of the Coupling in a Fast-Slow System
Gabriele Vissio, Valerio Lucarini
Constructing accurate, flexible, and efficient parametrizations is one of the great challenges in the numerical modelling of geophysical fluids. We consider here the simple yet par…
Convergence of extreme value statistics in a two-layer quasi-geostrophic atmospheric model
Vera Melinda Galfi, Tamas Bodai, Valerio Lucarini
We search for the signature of universal properties of extreme events, theoretically predicted for Axiom A flows, in a chaotic and high dimensional dynamical system by studying the…
A proof of concept for scale-adaptive parameterizations: the case of the Lorenz '96 model
Gabriele Vissio, Valerio Lucarini
Constructing efficient and accurate parameterizations of sub-grid scale processes is a central area of interest in the numerical modelling of geophysical fluids. Using a modified v…
Dynamical Analysis of Blocking Events: Spatial and Temporal Fluctuations of Covariant Lyapunov Vectors
Sebastian Schubert, Valerio Lucarini
One of the most relevant weather regimes in the mid-latitudes atmosphere is the persistent deviation from the approximately zonally symmetric jet to the emergence of blocking patte…
Covariant Lyapunov Vectors of a Quasi-geostrophic Baroclinic Model: Analysis of Instabilities and Feedbacks
Sebastian Schubert, Valerio Lucarini
The classical approach for studying atmospheric variability is based on defining a background state and studying the linear stability of the small fluctuations around such a state.…
