Relaxed Structures in NLC Dynamics in the Mesosphere

This article presents dusty plasma’s self-organized state (electrons, ions, and dust particles with negative charge) in the Earth’s mesosphere. The momentum-balanced equation describes the species dynamics. A triple Beltrami (TB) state is observed when the steady-state solutions for the magnetic field are solved using Ampère’s law. TB state, which combines three distinct Beltrami states, is the subject of this study. We have used cylindrical geometry to find the profile of the magnetic field. We have observed magnetic field profiles for three categories: the variation of Beltrami parameters (BPs), the variation of day and night time events in the Earth’s mesosphere for noctilucent cloud (NLC) structures, and the mass of dust grain. For these categories, diamagnetic and paramagnetic behavior has been observed in the Earth’s mesosphere Earth. This research contributes to a better understanding mesospheric plasma behavior, offering insights into phenomena such as polar mesospheric summer echoes (PMSE) and NLC structures. The findings also provide crucial implications for future environmental studies and the broader understanding of the Earth’s upper atmosphere.
