Linking Horizontal and Vertical Submesoscale Lagrangian Dynamics South of the Ibiza Channel
Sara Cloux, Ismael Hernandez-Carrasco, Alejandro Orfila +2
Fronts, eddies, jets, and meanders populate the ocean surface and play a key role in organizing transport and mixing across a wide range of scales. From a Lagrangian perspective, f…
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…
Integrating theory and experiments to link local mechanisms and ecosystem-level consequences of vegetation patterns in drylands
Ricardo Martinez-Garcia, Ciro Cabal, Justin M. Calabrese +4
Self-organized spatial patterns of vegetation are frequent in drylands and, because pattern shape correlates with water availability, they have been suggested as important indicato…
Structured interactions as a stabilizing mechanism for competitive ecosystems
Violeta Calleja-Solanas, Nagi Khalil, Jesús Gómez-Gardeñes +2
How large ecosystems can create and maintain the remarkable biodiversity we see in nature is probably one of the biggest open questions in science, attracting attention from differ…
Landscape-induced spatial oscillations in population dynamics
Vivian Dornelas, Eduardo H. Colombo, Cristóbal López +2
We study the effect that disturbances in the ecological landscape exert on the spatial distribution of a population that evolves according to the nonlocal FKPP equation. Using both…
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…
Nonlocal birth-death competitive dynamics with volume exclusion
Nagi Khalil, Cristóbal López, Emilio Hernández-García
A stochastic birth-death competition model for particles with excluded volume is proposed. The particles move, reproduce, and die on a regular lattice. While the death rate is cons…
Active cluster crystals
Jean-Baptiste Delfau, Cristóbal López, Emilio Hernández-García
We study the appearance and properties of cluster crystals (solids in which the unit cell is occupied by a cluster of particles) in a two-dimensional system of self-propelled activ…
Modeling the dynamical sinking of biogenic particles in oceanic flow
Pedro Monroy, Emilio Hernández-García, Vincent Rossi +1
We study the problem of sinking particles in a realistic oceanic flow, with major energetic structures in the mesoscale, focussing in the range of particle sizes and densities appr…
Hydrodynamic provinces and oceanic connectivity from a transport network help designing marine reserves
Vincent Rossi, Enrico Ser-Giacomi, Cristóbal López +1
Oceanic dispersal and connectivity have been identified as crucial factors for structuring marine populations and designing Marine Protected Areas (MPAs). Focusing on larval disper…
Exploring the tug of war between positive and negative interactions among savanna trees: Competition, dispersal, and protection from fire
Flora S. Bacelar, Justin M. Calabrese, Emílio Hernández-García
Savannas are characterized by a discontinuous tree layer superimposed on a continuous layer of grass. Identifying the mechanisms that facilitate this tree-grass coexistence has rem…
Lagrangian transport in a microtidal coastal area: the Bay of Palma, island of Mallorca, Spain
Ismael Hernández-Carrasco, Cristóbal López, Alejandro Orfila +1
Coastal transport in the Bay of Palma, a small region in the island of Mallorca, Spain, is characterized in terms of Lagrangian descriptors. The data sets used for this study are t…
Characterization of coherent structures in three-dimensional flows using the finite-size Lyapunov exponent
João H Bettencourt, Cristóbal López, Emilio Hernández-García
In this paper we use the finite size Lyapunov Exponent (FSLE) to characterize Lagrangian coherent structures in three-dimensional (3d) turbulent flows. Lagrangian coherent structur…
The reduction of plankton biomass induced by mesoscale stirring: a modeling study in the Benguela upwelling
Ismael Hernández-Carrasco, Vincent Rossi, Emilio Hernández-García +2
Recent studies, both based on remote sensed data and coupled models, showed a reduction of biological productivity due to vigorous horizontal stirring in upwelling areas. In order…
Oceanic three-dimensional Lagrangian Coherent Structures: A study of a mesoscale eddy in the Benguela ocean region
João H. Bettencourt, Cristóbal López, Emilio Hernández-García
We study three dimensional oceanic Lagrangian Coherent Structures (LCSs) in the Benguela region, as obtained from an output of the ROMS model. To do that we first compute Finite-Si…
How reliable are Finite-Size Lyapunov Exponents for the assessment of ocean dynamics?
Ismael Hernández-Carrasco, Emilio Hernández-García, Cristóbal López +1
Much of atmospheric and oceanic transport is associated with coherent structures. Lagrangian methods are emerging as optimal tools for their identification and analysis. An importa…
Burridge-Knopoff Models as Elastic Excitable Media
Julyan H. E. Cartwright, Emilio Hernández-García, Oreste Piro
We construct a model of an excitable medium with elastic rather than the usual diffusive coupling. We explore the dynamics of elastic excitable media, which we find to be dominated…
