Calculation of the height for noctilucent clouds in the atmosphere Е. М. Apfelbaum, Yu. P. Vlasov, S. А. Trigger
The process deceleration for micrometeorites is considered in the upper Earth atmosphere. This process can lead
to the creation on the height of order 70—90 km. So-called the Noctilucent Clouds. These clouds at some conditions
can be visualized by the eye. Explanation of the height and the typical structure of these clouds has no systematic
solution because the correct description of the essen-tial forces, acting on micrometeorites, as well as the parameters
of the micrometeorites was not yet done with the necessary accuracy. The developed model gives a simple and effective
way to consider the deceleration of the micrometeorites. The non-stationary solution will be considered in the separate
publication. For the stationary solution we found the reasonable agreement between the observations and our calculations.
