| Summary: | High power radio wave heating of the ionospheric plasma can induce disturbances of electron temperature and density, and modify the ionosphere. The numerical model can be presented from a series of continuity equation, momentum equation and energy equation. The heating disturbances of the electron density and temperature in polar ionosphere are presented and the effects of the pump parameters are discussed. It shows that electron temperature almost increases in all altitude, however,the peak at the reflection altitude is not clear. Electron density vale is formed at the altitude above peak, and density peaks appear around both sides of it. The heating characteristic increases with the increment of the heating power and the decrement of the pump frequency. Using the parameters of the ionospheric modification experiments carried out in January 2008 at Tromso, Norway as initialization, the six 0 mode heating cases are simulated, and the results are consistent with the observation very well.
