Abstract: Effects of variations of magnitude of E×B vertical drifts and neutral windson low-latitude ionosphere are investigated by using a two-dimensional low-latitudeionospheric time-dependent theoretical model. In the model ion transport equationsare solved by using splitting technique at fixed grid points along magnetic field lines,and densities and velocities of ions are outputted on the given geomagnetic meridian.Modelling results show that the influences of adjusted magnitude of E×B verticaldrifts and neutral winds on low-latitude f₀F2 are dependent on magnetic latitudeand local time. And some features not reported previously are also mentioned inthe paper.
