中纬度观测的电离层F区经度效应及其模式计算

OBSERVATIONS OF THE LONGITUDE EFFECTS IN THE MID-LATITUDE IONOSPIIERIC F-REGION AND COMRISONS WITH MODELS

利用1956—1994年期间分别在长春和乌鲁木齐两观测站上观测的f0F2和f0F1月中值，定量分析了两站上观测的经度效应，讨论了产生两站上经度效应的可能物理机制，并与国际参考电离层模式的结果进行了比较．

Longitude effect in the mid-latitude F region is studied in this paper, using monthly median value f0F2 and f0F1 observed at Changchun and Urumqi,China from 1956 to 1994. Results are compared with the IRI-90 model. Physical mechanism leading to the longitude effect is discussed with the help of the IRI-90 and MSISE90 models.
