An interplanetary origin of great geomagnetic storms: multiple magnetic clouds

特大地磁暴的一种行星际源：多重磁云

This paper provides a statistical study of the variation of the Atmospheric Vorticity Area Index ( VAI) during geomagnetic storms for 1966-1978. The results show that the influence of geomagnetic storms on VAI is very obvious.

本文分析了1966&1978年间地磁暴期间地球大气气旋的变化。在地磁暴发生后，大气涡度面积指数（VAI）出现明显的扰动。

Comparing with the same period in last solar cycle when the solar activity was stronger, number of geomagnetic storms was significantly reduced.

对比上一活动周相同时间段发现，在这段太阳活动极低的时间，地磁暴的数目显著减少。
