| Zusammenfassung |
| The quasi-periodical disturbances of natural geomagnetic field in the frequency range 5-20 Hz registered at CHAMP satellite are analyzed and compared with ground data. Occurrence rates of coherent signals in the ionosphere and at the ground at different frequencies are studied and a maximum near the first Schumann resonance frequency is found. However, no relation of observed 8 Hz signal in the F-layer with thunderstorm activity is seen andthe latitude distribution demonstrates a clear polar maximum. Different mechanisms for excitation of several Hz disturbances in the F-layer are discussed. |
