Регрессионные зависимости электронной концетрации области F2 ионосферы от солнечной активности по данным Харьковского радара некогерентного рассеяния

Abstract

Dependence of the F-region electron density peak (Nm) for 12 LT from the solar activity level is investigated. The regression's coefficients of dependence of the Nm from the solar activity for every month had calculated. Then regression's coefficients had used for calculation of seasonal variations of the Nm. Good agreement between calculated and an experimental seasonal variation of the Nm under any solar activity level is obtained. The features and possible reasons of the seasonal variations of the Nm for different solar activity level are considered
