日地共转扰动似稳结构及其反相和漂移规律的最新证据

日地共转扰动似稳结构及其反相现象在第２１及２２周再次显现，从而证实了上述发现是一种在长达世记的时间尺度内存在的普遍规律。包括１９９１－１９９２年内的百年地磁扰动资料还说明偶数太阳周的共转似稳结构扰动峰有逆太阳自转而线性性漂移的趋向。对即将来临的极小年前可能出现的共转扰动作了试验性的预测。

NEW EVIDENCE OF THE QUASI-STEADY STRUCTURES IN THE SOLAR-TERRESTRIAL COROTATING DISTURBANCES AND THEIR PHASE REVERSAL AND DRIFT

The quasi-steady structures in the corotating solar-terrestrial disturbances and their phase reversal reappear in the solar cycle 21 and 22,which confirms that the above phefiomenon found by the authors is a regular feature occurring on a time scale of one century.Moreover,the geomagnetic disturbance data covering the past one hundred years up to 1991-1992 indicated that the quasi-steady corotating structure in the even cycles tends to drift linearly in peak against solar rotation.A tentative prediction is made for the corotating disturbances which may appear in the forthcoming pre-minimum years.
