| 英文摘要 | The annual and semi-annual variations of the ionosphere are investigated in the present paper by using the daytime F2 layer peak electron concentration (NmF2) observed at a global ionosonde network with 104 stations. The main features are outlined as follows. (1) The annual variations are most pronounced at magnetic latitudes of 40-60degrees in both hemispheres, and usually manifest as winter anomalies: Below magnetic latitude of 40degrees as well as in the tropical region they are much weaker and winter anomalies that are not obvious. (2) The semi-annual variations. which are usually peak in March or April in most regions, are generally weak in the near-pole legions and strong in the far-pole regions of both hemispheres. (3) Compared with their annual components. the semi-annual variations in the tropical region are more significant. |
