We consider the evolution of the correlations between the Fourier coeficientsof a solution of the Kamdostev-Petviavshvili II equation when thesecoefficients are initially independent random variables. We use the structureof normal forms of the equation to prove that those correlations remain smalluntil times of order $\varepsilon^{-5/3}$ or $\varepsilon^{-2}$ depending onthe quantity considered.

On the use of normal forms in the propagation of random waves
