Revisiting the Dynamical Properties of Pedlosky's Two-Layer Model for Finite Amplitude Baroclinic Waves
Nicolas De Ro, Jonathan Demaeyer, Stéphane Vannitsem
Baroclinic instability is a fundamental mechanism driving atmospheric dynamics. In this work, we revisit Pedlosky's two-layer model for finite amplitude baroclinic waves - a semina…
Spread/Error relationship and spatial error structure of precipitation ensemble nowcasting: Comparison of STEPS and generative AI
Martin Bonte, Lesley De Cruz, Fabian Debal +1
The predictability of the generative AI-based nowcasting model LDCast (trained on another region) is evaluated over Belgium, together with the pysteps implementation of the nowcast…
Predictability of north Pacific blocking events : Analogue based analysis of historical MIROC6 simulations
Anupama K Xavier, OisÃn Hamilton, Davide Faranda +1
Atmospheric blocking exerts a profound influence on mid-latitude circulation, yet its predictability remains elusive due to intrinsic non-linearities and sensitivity to initial-con…
Using Unstable Periodic Orbits to Understand Blocking Behaviour in a Low Order Land-Atmosphere Model
OisÃn Hamilton, Jonathan Demaeyer, Michel Crucifix +1
Unstable Periodic Orbits (UPOs) were used to identify regimes, and transitions between regimes, in a reduced-order coupled atmosphere-land spectral model. In this paper we describe…
Sources of low-frequency O variability in coastal ice cores from Dronning Maud Land
Stéphane Vannitsem, David Docquier, Sarah Wauthy +2
The low-frequency variability of the O recorded in ice cores (FK17 and TIR18) recently drilled at two different locations in Dronning Maud Land (Antarctica), is investigat…
