The stochastic skeleton model for the Madden–Julian Oscillation with time-dependent observation-based forcing Open
We analyze solutions to the stochastic skeleton model, a minimal non-linear oscillator model for the Madden–Julian Oscillation (MJO). This model has been recognized for its ability to reproduce several large-scale features of the MJO. In p…

Simple physics-based adjustments reconcile the results of Eulerian and Lagrangian techniques for moisture tracking in atmospheric rivers Open
The increase in the number and quality of numerical moisture tracking tools has greatly improved our understanding of the hydrological cycle in recent years. However, the lack of observations has prevented a direct validation of these tool…

Flow spatial structure determines pattern instabilities in nonlocal models of population dynamics Open
Environmental flows shape spatial patterns and population dynamics; however, we do not fully understand how they influence the onset of pattern formation and population abundance. By combining numerical simulations and analytical approxima…

Proliferating active disks with game dynamical interaction Open
We study a system of self-propelled, proliferating finite-size disks with game-theoretical interactions, where growth rates depend on local population composition. We analyze how these interactions influence spatial distribution, coexisten…

Flow spatial structure determines pattern instabilities in nonlocal models of population dynamics Open
We investigate how environmental flows influence spatial pattern formation and population dynamics using two nonlocal models of population dynamics, which we couple to two different stationary flows. Combining numerical simulations and ana…

Wave breaking events and their Link to Rossby wave packets and atmospheric blockings during Southern Hemisphere Summer Open
Rossby Wave Packets (RWPs) are atmospheric perturbations located at the upper levels in mid‐latitudes which, under certain circumstances, terminate in Rossby Wave Breaking (RWB) events. When RWB events are sufficiently persistent and…

Extinction and coexistence in a binary mixture of proliferating motile disks Open
A binary mixture of two-different-size proliferating motile disks is studied. As growth is space limited, we focus on the conditions such that there is a coexistence of both large and small disks, or dominance of the larger disks. The stud…

Pulsed interactions unify reaction–diffusion and spatial nonlocal models for biological pattern formation Open
The emergence of a spatially organized population distribution depends on the dynamics of the population and mediators of interaction (activators and inhibitors). Two broad classes of models have been used to investigate when and how self-…

Unraveling vertical dynamics: Estimating oceanic transport in marine debris dispersal using circulation structures and Lagrangian tools. Open
Marine litter, particularly plastic pollution, has become a pressing environmental concern, requiring extensive knowledge of its distribution and effects [Chassignet et al., 2021; Wayman et al., 2021]. Therefore, it is important to conside…
