L'évolution d'une turbulence homogène cisaillée stablement stratifiée est étudiée en fonction de deux paramètres adimensionnels : le nombre de Richardson Ri et le nombre de Prandtl Pr. Une analyse linéaire dans l'espace spectral permet d'accéder à l'évolution des différentes grandeurs physiques caractéristiques d'une telle turbulence (tensions de Reynolds, énergie cinétique, énergie potentielle, flux...
