Saturation of a large scale instability and non linear stuctures in a rotating stratified flow

Abstract

In this letter, we present non linear structures resulting from the saturation of a large scale instability in rotating stratified fluids with small scale forced turbulence which we found in \cite{[1]}. These structures are of helical kinks type. The different solutions that we plotted correspond to solutions linking two different stationnary points for different values of the Rayleigh and the Taylor numbers.
