Lagrangian Rotating Contracting Structures
F. J. Beron-Vera
We identify materially defined regions in unsteady two-dimensional flows that combine finite-time contraction with elevated accumulated intrinsic rotation along trajectories, which…

Material coherence and life cycle of a wildfire-generated stratospheric vortex
F. Andrade-Canto, F. J. Beron-Vera
Pyro-cumulonimbus convection associated with extreme wildfires can generate long-lived vortical structures in the stratosphere. These structures have been described as coherent, ye…

Transition path theory insights into hurricane rapid intensification
F. J. Beron-Vera, G. Bonner, M. J. Olascoaga +2
We explore hurricane and ocean reanalysis data to understand how rapid intensification (RI) of tropical cyclones is impacted by the upper ocean density structure, with an emphasis…
