Finding a reconnection in a vortex-haystack
Abhishek Harikrishnan, Benjamin Musci, Adrien Lopez +8
Counter-rotating vortex reconnection is a topology-transforming event that leads to strong vorticity amplification and is often associated with the most irregular regions of the ve…
Viscous and Inviscid Reconnection of Vortex Rings on Logarithmic Lattices
Abhishek Harikrishnan, Adrien Lopez, Bérengère Dubrulle
To address the possible occurrence of a Finite-Time Singularity (FTS) during the oblique reconnection of two vortex rings, Moffatt-Kimura (MK) (J. Fluid Mech., 2019a; J. Fluid Mech…
On the motion of hairpin filaments in the atmospheric boundary layer
Abhishek Harikrishnan, Marie Rodal, Rupert Klein +2
A recent work of Harikrishnan et al. [arXiv:2110.02253 (2021)] has revealed an abundance of hairpin-like vortex structures, oriented in a similar direction, in the turbulent patche…
Geometry and organization of coherent structures in stably stratified atmospheric boundary layers
Abhishek Harikrishnan, Cedrick Ansorge, Rupert Klein +1
Global intermittency is observed in the stably stratified Atmospheric Boundary Layer (ABL) and corresponds to having large nonturbulent flow regions to develop in an otherwise turb…
Definition, detection, and tracking of persistent structures in atmospheric flows
Johannes von Lindheim, Abhishek Harikrishnan, Tom Dörffel +8
Long-lived flow patterns in the atmosphere such as weather fronts, mid-latitude blockings or tropical cyclones often induce extreme weather conditions. As a consequence, their desc…
