摘　　要：本文给出了太阳活动高年(57—59年)几次磁暴主相期间电离层暴的全球形态。发现,电离层暴的地区特征,季节特性以及负扰范围的大小与暴强度的变化有关;特大暴可使低纬及赤道带呈负扰;冬半球中纬地磁异常区 F 层,呈正扰,且正扰范围随暴的增强而变小。This paper presents the global morphology of several ionospheric storms during a period of high solar activitys(1957—1959).The regional and the seasonal features as well as the relation- ships between latitude range of negative disturbanee and the strength of magnetic storms are summarized.It shows that specially strong storms can cause negative disturbance in low—latitude and even in equatorial areas while positive disturbances are caused in mid—latitude areas of anomoly geomognetic field in the winter hemisphere.The range of positive disturbance is de- creased when the strength of magnetic storm is increased.
