| 摘 要： | 对重庆(29.5,106.6)与兰州(36,103.9)f0Es>5MHz的Es出现率和E层临界频率f0E进行了详细对比研究.结果表明(1)此两地Es出现率的变化特征显著.白天重庆高于兰州;晚上则正相反.(2)出现率的这种变化与Es环境电离密度的变化趋势十分一致.(3)上述特征的形成,除了此两地纬度上的差异外,与兰州地处地磁Sq电流系的焦点很有关系.

| Abstract: | In this paper, Es occurrence and f0E over Chongqing (29.5,106.6) and Lanzhou (36, 103.9) are comparedand studied. The results show that: (1) Change pattern of Esoccurrence over these two stations has certain rules. During thedaytime, Es occurrence over Chongqing is higher than that overLanzhou, but at night the result is just the opposite. (2)Change of Es occurrence is consistent to that of theambient ionization density. (3) Besides the difference of latitudeof the two stations, it seems that the mechanism of the abovecharacteristic is closely related to the S{ q currentsystems. |
