| 英文摘要 | On the basis of Hibberd's method, a technique is developed for separating main components of the variable geomagnetic field. This technique makes it possible to quantitatively determine the intensity of S(q), D(st) and other irregular variations for eve every day. An examination is made by the use of magnetic data obtained from the stations at the East Asia Meridian Chain. The results show that (1) The spacial structure of the large-scale ionospheric current system at middle and low latitudes is fairly stable, even during distributed periods; (2) Complicated magnetic variations during distributed periods are mainly caused by the magnetospheric ring current, field-aligned current and high latitude current; (3) Day-to-day variability of S(q) exhibits mainly in the daily range, that suggests a stable structure and variable intensity of the ionospheric dynamo current system responsible for S(q) variation. |
