极光

In this dissertation, EISCAT radar observations and computer numerical simulation methods are involved to study the climatologic characteristics of polar ionosphere and their mechanisms, as well as the polar ionospheric responses to magnetospheric particle precipitation and convection electric field. Then, with the help of the numerical computation, the EISCAT data are employed to invert the energy spectra of auroral precipitating particles and their responses to magnetic storms and substorms.

本文联合利用EISCAT雷达数据和计算机数值模拟手段，以雷达探测数据为基础，数据分析和数值模拟、理论研究相结合，研究了极区电离层气候学特征与机制，磁层粒子沉降和对流电场对极区电离层的影响，并利用雷达数据反演极光沉降粒子能谱特征及其对磁暴和亚暴的响应。

With EISCAT radar observations during 1988～1999, the climatologic features of electron densities in the auroral ionospheric Fregion have been investigated statistically and compared with the IRI2001 model for different seasons at different phases of the solar cycle.
