However, the dusty plasma nature of noctilucent clouds has been neglected. A specific feature observed in noctilucent clouds is wavy, turbulent structure. However, although being an interesting point by itself, we emphasize that our simulations are not sufficiently appropriate regarding the vertical dynamics in noctilucent clouds. Thus, our simulations offer new insight into the dynamics of noctilucent clouds. The occurrence of noctilucent clouds appears to be increasing in frequency, brightness and extent.

The clouds thus generated are intended to simulate naturally occurring phenomena called noctilucent clouds, which are the highest clouds in the atmosphere.
