Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
Dynamic and thermodynamic contributions to future extreme-rainfall intensification: a case study for Belgium
Jozefien Schoofs, Kobe Vandelanotte, Hans Van de Vyver +5
Extreme precipitation is projected to become more frequent and more intense due to climate change and associated thermodynamical effects, but the local response of atmospheric circ…
Self-attentive Transformer for Fast and Accurate Postprocessing of Temperature and Wind Speed Forecasts
Aaron Van Poecke, Tobias Sebastian Finn, Ruoke Meng +6
Current postprocessing techniques often require separate models for each lead time and disregard possible inter-ensemble relationships by either correcting each member separately o…
Robust intra-model teleconnection patterns for extreme heatwaves
George Miloshevich, Philippine Rouby-Poizat, Francesco Ragone +1
We investigate the statistics and dynamics of extreme heat waves over different areas of Europe. We find heatwaves over France and Scandinavia to be associated with recurrent waven…
Interface potential and line tension for Bose-Einstein condensate mixtures near a hard wall
Bert Van Schaeybroeck, Patrick Navez, Joseph O. Indekeu
Within Gross-Pitaevskii (GP) theory we derive the interface potential V (l) which describes the interaction between the interface separating two demixed Bose-condensed gases and an…
Brownian motion in a growing population of ballistic particles
Nathaniel V. Mon Père, Pierre de Buyl, Sophie de Buyl
We investigate the motility of a growing population of cells in a idealized setting: we consider a system of hard disks in which new particles are added according to prescribed gro…
Identifying efficient ensemble perturbations for initializing subseasonal-to-seasonal prediction
Jonathan Demaeyer, Stephen G. Penny, Stéphane Vannitsem
The prediction of the weather at subseasonal-to-seasonal (S2S) timescales is dependent on both initial and boundary conditions. An open question is how to best initialize a relativ…
Applications of large deviation theory in geophysical fluid dynamics and climate science
Vera Melinda Galfi, Valerio Lucarini, Francesco Ragone +1
The climate system is a complex, chaotic system with many degrees of freedom and variability on a vast range of temporal and spatial scales. Attaining a deeper level of understandi…
Lees-Edwards boundary conditions for translation invariant shear flow: implementation and transport properties
Sebastian Bindgen, Florian Weik, Rudolf Weeber +2
Molecular dynamics (MD) simulations represent a powerful investigation tool in the field of soft matter. By using shear flows, one can probe the bulk rheology of complex fluids, al…
Deep Learning-based Extreme Heatwave Forecast
Valérian Jacques-Dumas, Francesco Ragone, Pierre Borgnat +2
Because of the impact of extreme heat waves and heat domes on society and biodiversity, their study is a key challenge. We specifically study long-lasting extreme heat waves, which…
Extratropical low-frequency variability with ENSO forcing: A reduced-order coupled model study
Stéphane Vannitsem, Jonathan Demaeyer, Michael Ghil
The impact of the El Niño-Southern Oscillation (ENSO) on the extratropics is investigated in an idealized, reduced-order model that has a tropical and an extratropical module. Unid…
Dual View on Clear-Sky Top-of-Atmosphere Albedos from Meteosat Second Generation Satellites
Alexandre Payez, Steven Dewitte, Nicolas Clerbaux
Geostationary observations offer the unique opportunity to resolve the diurnal cycle of the Earth's Radiation Budget at the top of the atmosphere (TOA), crucial for climate-change…
FRIPON: A worldwide network to track incoming meteoroids
F. Colas, B. Zanda, S. Bouley +14
Context: Until recently, camera networks designed for monitoring fireballs worldwide were not fully automated, implying that in case of a meteorite fall, the recovery campaign was…
Rare event algorithm study of extreme warm summers and heat waves over Europe
Francesco Ragone, Freddy Bouchet
The analysis of extremes in climate models is hindered by the lack of statistics due to the computational costs required to run simulations long enough to sample rare events. We de…
Statistical Postprocessing for Weather Forecasts -- Review, Challenges and Avenues in a Big Data World
Stéphane Vannitsem, John Bjørnar Bremnes, Jonathan Demaeyer +21
Statistical postprocessing techniques are nowadays key components of the forecasting suites in many National Meteorological Services (NMS), with for most of them, the objective of…
On temporal scale separation in coupled data assimilation with the ensemble Kalman filter
Maxime Tondeur, Alberto Carrassi, Stephane Vannitsem +1
Coupled data assimilation (CDA) distinctively appears as a main concern in numerical weather and climate prediction with major efforts put forward worldwide. The core issue is the…
On the use of near-neutral Backward Lyapunov Vectors to get reliable ensemble forecasts in coupled ocean-atmosphere systems
Stéphane Vannitsem, Wansuo Duan
The use of coupled Backward Lyapunov Vectors (BLV) for ensemble forecast is demonstrated in a coupled ocean-atmosphere system of reduced order, the Modular Arbitrary Order Ocean-At…
Correcting for Model Changes in Statistical Postprocessing -- An approach based on Response Theory
Jonathan Demaeyer, Stéphane Vannitsem
For most statistical postprocessing schemes used to correct weather forecasts, changes to the forecast model induce a considerable reforecasting effort. We present a new approach b…
European research on magnetic nanoparticles for biomedical applications: standardisation aspects
Peter Schier, Craig Barton, Simo Spassov +12
Magnetic nanoparticles have many applications in biomedicine and other technical areas. Despite their huge economic impact, there are no standardised procedures available to measur…
