【摘要】 研究赤道电离层泡的出现率与赤道带低平流层大气准两年振荡（ＱＢＯ）的关系．发现赤道电离层泡的出现率受到ＱＢＯ的调制．这种调制有很强的经度效应：在印度－东非扇区，ＱＢＯ东风向，赤道电离层泡出现率高；ＱＢＯ西风向，赤道电离层泡出现率低；在美洲扇区情况则与此相反．文章认为这是低纬电离层受到来自下边大气行星波扰动的又一证据更多还原

【Abstract】 The relationship between the percentage occurrence of the equatorial plasma bubble(EPB) and the Quasi-Biennial Oscillatioin(QBO) of the low-stratospheric mean zonal wind at equatorial zone has been investigated to reveal the QBO-modulation effect on the percentage occurrence of the EPB. A longitudinal deqendence of this QBO-modulation effect is also found: The percentage occurrence of the EPB is increase(decrease) in the east phase of the QBO at India-East Africa Sector(at America Sector);and it is decrease(increase) in the west phase of the QBO at India-East Africa sector(at America sector).It is suggested that this represents a new evidence that the low-latitude ionosphere is modulated by the atmospheric planetary wave from below.更多还原
