| Zusammenfassung |
| A numerical model of the high-latitude
ionosphere, which takes into account the convection of the ionospheric plasma,
has been developed and utilized to simulate the F-layer response at auroral
latitudes to high-power radio waves. The model produces the time variations of
the electron density, positive ion velocity, and ion and electron temperature
profiles within a magnetic field tube carried over an ionospheric heater by the
convection electric field. The simulations have been performed for the point
with the geographic coordinates of the ionospheric HF heating facility near
Tromso, Norway, when it is located near the midnight magnetic meridian. The
calculations have been made for equinox, at high-solar-activity, and
low-geomagnetic-activity conditions. The results indicate that significant
variations of the electron temperature, positive ion velocity, and electron
density profiles can be produced by HF heating in the convecting high-latitude F
layer. |
