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…
Structural Origins and Real-Time Drivers of Intermittency
Alessandro Barone, Alberto Carrassi, Thomas Savary +2
In general terms, intermittency is the property for which time evolving systems alternate among two or more different regimes. Predicting the instance when the regime switch will o…
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…
