ON THE DEVELOPMENT OF IONOSPHERIC Es-s OVER WUCHANG,CHINA AND ITS RELATED FACTORS
-
摘要: 本文对武昌上空电离层Es-s作了进一步分析研究与理论探讨,其结果表明:1.Es-s的出现正比于因子K=1/G(f0E√fmin。2.仪器功率对Es-s,出现率有显著影响。3.Es-s之所以表现为非磁扰日现象,乃是由于磁扰时fmin较高,妨碍了对它的观测。4.武昌上空Es-s的出现既具有前兆征候又带有后迹现象,井与由声重力波引起的分层有关。联系武昌上空电离层其它某些参量的共同特点,有可能月致效应是其共同的推动源。Abstract: In this paper,data of ionospheric Es-s over Wuchang,China are analyzed and theoretical investigation are made.It shows that:(1) The occurrence of Es-s is in proportion to a factor K=1/G(f0Efmin (2)The occurrence of Es-s is also clearly influenced by the power of the equipment used.(3)Es-s seems to be a phenomenon in non-magnetically disturbed days,which is due to the fact that the observability is limited by the high fmin in disturbed days.(4)Proper related phenomena exist both as "the prelude" and "the postlude" to the occurrence of Es-s over Wuchang.Generally,there also exists stratification due to acoustic gravity waves.Judging from these and other ionospheric features over Wuchang,the lunar effect may serve as a common source.
