用经验模式参数研究电离层发电机效应

A STUDY OF THE IONOSPHERIC DYNAMO BY USING EMPIRICAL MODEL PARAMETERS

本文利用MSIS-86和IRI-86模式的基本参数,求得热层风系和电导率的三维分布;继而从发电机理论得到了电离层电位及层电流密度在北半球的分布和变化。本研究将大量数据统计平均的大气模式参数与热层、电离层理论研究联系了起来。

The empirical parameters of MSIS-86 and IRI-86 are used to deduce the three dimensional distribution of ionospheric conductivity and thermospheric wind system.Furthermore,the distribution and variation of the electrostatic potential and layer ionospheric current density at the Northern Hemisphere are calculated by the dynamo theory.The work combines the theoritical research of the ionosphere and thermosphere and the parameters of empirical model based on vast amount of data.The thermospheric wind system,height-integrated conductivity,electrostatic potential and ionospheric current density are compared with observed data and the results deduced from model calculations.There is a good agreement between them.The general significance of the method engaged is discussed too.
