Presenter: Safi Ullah事实上一点红心水高手论坛, 内容简介:A number of theoretical and experimental work has been conducted in past considering the turn-off period, the objective here is to consider further possibilities for diagnostic information available as well as the underlying physical processes of Polar mesosphere summer echoes. During the turn-off of the radio wave heating, then from the temporal behavior of the electron irregularities, to obtain possible diagnostic information for various charged dust and background plasma quantities the analytical models are used. New 2D PME heating model will be built based on the equilibrium and non-equilibrium space conditions. After that comparing the new 2D results with that of PME heating experiment, improve and perfect 2D model, at the same time I will try to establish a three-dimensional model.

The effect of artificial electron heating on polar mesosphere echoes

Supervisor: Prof. Lin Meng

Presenter: Abdur Rauf, PhD candidate of the School of Physical Electronics香港伯乐汇高手论坛(Discipline: Physics)

内容简介:Over several decades polar mesosphere summer echoes (PMSE) have been studied extensively due to their important role in monitoring, t想知道伯乐高手心水主论坛he thermal and dynamical structure of the mesopause region allowing insights into important atmospheric key parameters like neutral temperatures, winds, gravity wave parameters, turbulence, solar cycle effects, and long term changes, it is still required to understand the physics of PMSE phenomenon. There are many aspects which are still needed for investigating the mechanism responsible for PMSE creation. Here by employing the Pearson linear and Spearman rank correlation coefficient method, the apparent electron density at two different precipitation altitude of about 90 and 100 km, and PMSE altitude between about 80 and 90 km were compared to investigate the effect of particle precipitation on PMSE intensity. The precipitating particle fluxes reaching to D-region, lost part of their energy in ionizing atoms and provides free electrons necessary for PMSE, so our study could be helpful in understanding the physics of PMSE.
