| 摘 要： | 利用中国地区广州和海口两个常规观测站一个太阳周的历史数据(1996～2006年),根据突发E层(Es层)临界频率的不同取值范围对我国南部地区Es的出现概率和临界频率的变化规律进行了统计与理论分析.统计结果显示,中国地区是Es高发区,对于各种强度的Es层都是在夏季白天时段出现概率最大,最大可以达到90%以上;此外,Es层临界频率具有与F2层临界频率类似的变化规律,在正午时刻前后达到最大值,但Es层出现概率与太阳活动性没有绝对的依存关系.可见,Es层对夏季高频通信影响很大,白天时段受影响程度更大.

| Abstract: | The occurrence probability of sporadic E layer(Es) with critical frequencies greater than several special value and the distribution regularity of its critical frequency are studied,using data measured from China vertical stations of Haikou and Guangzhou for one solar period between January 1996 and December 2006.It is shown that China has more Es and the most significant occurrence probability presented during daytime in summer months,with maximum above 90%.Besides,the critical frequency distributed simila... |
