摘要
对印度Ｔｒｉｖａｎｄｒｕｍ站第２１太阳活动周内地磁Ｈ分量分析表明，不仅在磁扰日及其随后的静日内，强磁扰对赤道电集流有显著作用，即使在持续静日期间，较弱的磁扰仍然对赤道电离层有很大影响．磁静日昏侧出现反向（西向）电集流是正常现象，弱磁扰是使此反向电流消失的可能机制．
The data of geomagnetic H-component from Trivandrum,India, during 21-the solar cycle have been analysed.A new possible mechanism is introduced in discussion of the counter electrojet.The ionospheric disturbance dynamo and the ring current may drive strong westward ionospheric current on disturbed and following days. On the other hand, during quiet days the weak magnetospheric disturbance could impel the afternoon counter electrojet to disappear and this should be a normal phenomenon onreal quiet days.
