The effects of E-region electric fields on F-region parameters like height of constant electron density contours (h/sub n) and semithickness, at an equatorial station, Trivandrum, are investigated. The E-region east-west electric field (E/sub y) has been deduced using the horizontal magnetic field values from the ground magnetograms. It is found that the semi-thickness parameter and h/sub N/ follow closely the E-region electric field (E/sub y/) variations in the forenoon and noon periods. In the afternoon. it is shown that there is close association between h/sub N/ and E/sub y/ when the electric field variations are large. On a day-to-day basis also, h/sun N/ and the E-region electric field show very good correlation in the forenoon and noon hours. It is also shown that higher levels are affected more than the lower levels in the F- region bv E/sub y/. (auth)
