Numerical solutions of the continuity equation for electrons are obtained for the purpose of testing the vertical‐drift effect on the plasma distributions in the equatorial F region of the earth's ionosphere. The results have shown that the altitude profile of electron density and the accompanied vertical‐drift velocity measured at Jicamarca are consistent and confirmed that electromagnetic lifting is the major factor to cause the equatorial anomaly as suggested by Martyn [1955]. The calculated values are found to be in good agreement with the observations both in magnitudes and in distribution patterns.
