| 英文摘要 | The occurrence characteristics of medium-scale travelling ionospheric disturbances (MSTIDs) were investigated using the Tasman International Geospace Environment Radar (TIGER). From the occurrence study of sea echoes, we found two maxima, one pre-noon and the other after noon. They are less obvious with increase of magnetic activities, and more obvious when B, is northwards. It is suggested that this maxima were related to fore- and after-noon maxima in the distribution of net field-aligned Currents flowing from the magnetosphere to the ionosphere, and that these two regions were sources of atmospheric gravity waves (AGWs) due to enhancement of Hall conductivities in the ionosphere. The Lorentz force is suggested to be a possible mechanism for the excitation of MSTIDs in the dayside ionosphere. (C) 2007 Published by Elsevier Ltd on behalf of COSPAR. |
