Characteristic signatures of Northern Hemisphere blocking events in a Lagrangian flow network representation of the atmospheric circulation
Noémie Ehstand, Reik V. Donner, Cristóbal López +1
In the past decades, boreal summers have been characterized by an increasing number of extreme weather events in the Northern Hemisphere extratropics, including persistent heat wav…
Accumulated densities of sedimenting particles in turbulent flows
Alessandro Sozza, Gabor Drotos, Emilio Hernández-García +1
We study the effect of turbulence on a sedimenting layer of particles by means of direct numerical simulations. A Lagrangian model in which particles are considered as tracers with…
Classical analogies for the force acting on an impurity in a Bose-Einstein condensate
Jonas Rønning, Audun Skaugen, Emilio Hernández-García +2
We study the hydrodynamic forces acting on a small impurity moving in a two-dimensional Bose-Einstein condensate at non-zero temperature. The condensate is modelled by the damped-G…
A general model for vegetation patterns including rhizome growth
Daniel Ruiz-Reynés, Francesca Schönsberg, Emilio Hernández-García +1
Vegetation patterns, a natural phenomenon observed worldwide, are typically driven by spatially distributed feedback. However, the spatial colonization mechanisms of clonal plants,…
Using Network Theory and Machine Learning to predict El Niño
Peter D. Nooteboom, Qing Yi Feng, Cristóbal López +2
The skill of current predictions of the warm phase of the El Niño Southern Oscillation (ENSO) reduces significantly beyond a lag of six months. In this paper, we aim to increase th…
