THE MORPHOLOGY AND OCCURRENCE OF Es-s OVER WUCHANG,CHINA
-
摘要: 本文对武昌上空电离层Es-s的形态与出现规律进行了考察与统计分析。该地区的Es-s描迹清晰、出现频繁.表明Es-s既不单是磁扰的伴随现象,也不仅为极光地带与地磁赤道地区所特有。该地区的Es-s多出现于磁静日的白天.其出现率分别于地方时间九、十点(对于日变化)和夏季月份(对于年变化)达到最大;对于这一特征,既看不出地磁变化的影响,也看不出太阳活动的控制。Abstract: The occurrence and morphology of ionospheric Es-s over Wuchang,China,are examined and statistically analysed.The Es-s over this area is possessed of high occurrence and clear trace.We consider that Es-s is neither an intrinsic companion of magnetic disturbances,nor a phenomenon existing exclusively in the auroral zones and in the geomagnetic equatorial region. Over this area,Es-s occurred mostly in magnetic quiet days,and the maximum of occurrence rate is arround 09h or 10h LMT diurnally and in summer months seasonally.No effect on this feature due to variations of geomagnetic field or solar activity has so far been detected.
