A new method of a reduced description of systems with noise is developed. This method is based on the fact that among distributions of the solution of stochastic differential equations there are ones which may be described as similar to the kinetic description of states in statistical physics. The problem of the construction of asymptotic evolution operator is resolved by summing up secular terms of the perturbation series in a random field.
