The aim of our studies was to examine turbulent, wavy structures in noctilucent clouds taking into account the clouds dusty plasma nature.
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 possibility that small particles left behind on the orbital pathalmost one hundred days after the nucleus has passedcould form noctilucent clouds is also slim.
Noctilucent clouds may be confused with cirrus clouds, but appear sharper under magnification.
