The effects of geomagnetic activity on the F-region of the ionosphere

摘要: Abstract A study is made of the effects geomagnetic activity on F-region ionization by correlating parameters and Kp AE indices, using delays up to 33 h. The total electron content from a single station for years 1971–74 as well ƒ 0 F2 longitudinal chain stations around 150°E 1968–74 were used. Initially analyses carried out all data. They then divided according high or low in order separate magnetic storm quiet effects. Data sets each consisted 2-monthly segments hour day years. This enabled latitudinal, seasonal sunspot cycle correlations be detected. Significant positive with greater than few hours dominated winter results at lower latitudes; being predominantly negative higher latitudes. summer latitudes correlations. between 0–3 h obtained autumn latitude probably indicative electric fields. time lags 3 are consistent changes atmospheric neutral composition brought about modification global thermospheric circulation following heating auroral zones.
