Dependence of strong magnetic storm number on solar cycle
摘要
Abstract
Dependence of strong geomagnetic storm number with Dst≤-100 nT on solar cycle from 1957 to 2008 was statistically investigated. It is found that there is close relationship between the strong storm number and annual sunspot number. Dependence of strong storm number on difference phases of solar cycle revealed that more than 60% strong storms appeared in the declining phase. However, the maximum average annual occurrence rate still appeared in the year of the cycle maximum.关键词
