时现E层(指地球上电离空气的E层内不时出现的一种强烈电离层)
The data of 5 ionospheric vertical sounding stations before 4 earthquakes in Japan are analyzed. It is found that most of the critical frequencies of the E sporadic layer tended to decrease and the only few tended to increase around the epicenters before and after the earthquakes.
分析日本4次地震前5个电离层垂测站资料,发现地震前后震中附近夜间电离层偶发E层的临界频率f0ES值多数呈下降趋势,少数呈增加趋势。
