Smoke-charged vortices in the stratosphere generated by wildfires and their behaviour in both hemispheres : comparing Australia 2020 to Canada 2017
Hugo Lestrelin, Bernard Legras, Aurélien Podglajen +1
The two most intense wildfires of the last decade that took place in Canada in 2017 and Australia in 2019-2020 were followed by large injections of smoke in the stratosphere due to…
Isotopic profiles imply strong convective influence on water near the tropical tropopause
Maximilien Bolot, Bernard Legras, Kaley A. Walker +4
The influence of deep convection on water vapor in the Tropical Tropopause Layer (TTL), the region just below the high (18 km), cold tropical tropopause, remains an outstandi…
Evidence for a k^{-5/3} spectrum from the EOLE Lagrangian balloons in the low stratosphere
Guglielmo Lacorata, Erik Aurell, Bernard Legras +1
The EOLE Experiment is revisited to study turbulent processes in the lower stratosphere circulation from a Lagrangian viewpoint and resolve a discrepancy on the slope of the atmosp…
Dispersive and friction-induced stabilization of an inverse cascade. The theory for the Kolmogorov flow in the slightly supercritical regime
Bernard Legras, Barbara Villone
We discuss the stabilisation of the inverse cascade in the large scale instability of the Kolmogorov flow described by the complete Cahn-Hilliard equation with inclusion of eff…
Dispersive stabilization of the inverse cascade for the Kolmogorov flow
B. Legras, B. Villone, U. Frisch
It is shown by perturbation techniques and numerical simulations that the inverse cascade of kink-antikink annihilations, characteristic of the Kolmogorov flow in the slightly supe…
