The dynamical response of the middle atmosphere to weak perturbations induced at stratopause heights is studied. Simulation experiments have been carried out using a global 3-d numerical model of the middle atmosphere. The goal of the study is a better understanding of the physical mechanisms leading to significant correlations between oscillations in the lower and middle stratosphere and solar variability associated with the sun's rotation. Beside the definition of the initial conditions and of the structure of the forcing function there is evidence that stationary and transient planetary waves play an essential role for the development of the response signal.
