海南地区电离层骚扰的某些特征

本文分析了我国海南地区1965-1975年期间的电离层F₂层的临频偏移,发现骚扰的基本形态与国外文献报道的是一致的。但对某些持续几天的电离层大扰动,海南地区的F₂层的临频偏移具有明显的周期为24小时的重现性。为了比较,本文还分析了广州站（1964-1976）、武昌站（1968）和满洲里站（1965-1975）的F₂层的临频偏移,发现广州站也大体上同时出现这种24小时的重现现象,但满洲里没有这种现象。此外,分析结果还表明,电离层骚扰有很强的地区性,如在海南与满洲里站都很平静的情况下,武昌站可出现很强的扰动。

SOME FEATURE OF IONOSPHERIC DISTURBANCES OVER HAINANDAO AREA

This paper deals with the analysis of the f0F2 deviations during 1965-1975 over Hainandao area. Most of the characteristic features agree generally with those already published in the literature. It is found that during some severe positive storms the morphology of storms contains obvious multiple peaks with an interval of round 24 hours. For comparision we have also analyzed f0F2 deviations of ionopheric data over Guangzhou （1964-1976）, Wuhan （1968）, and Manzhouli （1965-1975）. The results show some remarkable features of local origin: 1) such recurrence of 24 hours occurs over Guangzhou, but not over Manzhouli. 2) strong ionospheric disturbances appear over Wuhan, while the conditions over other two stations are very quiet.
