Abstract

In this paper, an analytical model is used to analyze the modulated polar mesospheric winter echoes (PMWE). The winter parameters were introduced to simulate the effects of different parameters during the artificial electron heating of PMWE. The important role of the charged dust particle in the creation of PMWE is confirmed again. It is found that during the heating of PMWE, the increases of the dust size, dust charge, electron temperature, initial electron density, and ion-neutral collision frequency cause the increase of the electron density irregularity, and hence the PMWE strength. However, with increasing the dust density, the electron density irregularity and the PMWE strength decrease.

人工电子加热对极地平流层冬季回波影响的数值分析

本文利用一个分析模型对调制极地中层冬季回波（PMWE）进行了分析。引入冬季参数来模拟不同参数对PMWE人工电子加热的影响。带电尘埃粒子在PMWE产生中的重要作用再次得到证实。研究发现，在PMWE的加热过程中，灰尘尺寸、灰尘电荷、电子温度、初始电子密度和离子中性碰撞频率的增加导致电子密度不规则性的增加，从而导致PMWE强度的增加。然而，随着粉尘密度的增加，电子密度的不规则性和PMWE强度降低。
