| 摘 要： | Es是发生在电离层E层高度上的偶发不规则结构，其电子密度最高可达E层背景电子密度的100倍以上. 远东地区是全球Es的高发区，其相关研究具有独特性和典型性，该地区Es形态学特性的深入研究对于探索Es成因及揭示其本质具有重要意义. 本文利用中国电离层垂测网50余年的垂测数据，结合日本垂测网数据对东亚地区Es的强度特性、空间分布特性、日变化、季节变化以及长期变化趋势进行了深入分析，得到一些有意义的结论.

| Abstract: | Sporadic E (Es) is the irregular structure of ionosphere occurred in the layer E sporadically, and the highest electron density can exceed the background by more than 100 times. In East Asia, the Es is of frequent occurrence, and the Es morphological characteristics research in this region has the uniqueness and typicality, which is of great significance to explore the cause and reveal the essence of Es. Based on more than fifty years' data from Chinese ionospheric vertical sounders, and combining with the Japanese vertical sounders data, the strength characteristics, spatial distribution characteristics, daily variations, seasonal changes and long-term trends of the Es over East Asia were studied, and conclusions are obtained. |
