Teoretical nonstationary two-dimensional modal with altitude-longitudinal variations of ionosphere parameters
By means of mathematical two-dimensional nonstationary model mechanisms of formation of longitudinal effect in a middle-latitude ionosphere are probed and is shown that one of main engines is the thermosphere wind in combination with earth magnetic field geometry. Model calculations of dependence of longitudinal effects in middle-latitude F-area from levels of geomagnetic and solar activity are carried out. It is shown that with increase in a geomagnetic disturbance ...
