EFFECTS OF THE SOLAR ECLIPSE ON f0F2 AND ICF FOR LOW LATITUDE REGION
-
摘要: 研究了1995年10月24日日食过程中,我国低纬地区广州和海口的F2层临界频率f0F2和高频干扰重心频率ICF变化过程．鉴于多次日食期间,同处低纬的两地f0F2的日食变化形态不完全一样,以及多次日食期间同一地方f0F2变化形态不完全一样,ICF也并不像预想的那样降低,因而对于低纬电离层,动力学过程可能要比直接与太阳辐射有关的光化学过程起更为重要的作用．Abstract: The variations of the critical frequency of F2 layer (f0F2) and the HFinterference centroid frequency (ICF) at Guangzhou and Haikou during the solar eclipseoccurring on Oct. 24, 1995, are presented. The morphology of f0F2 for two differentstations is not completely same for the same solar eclipse; the mophology of thesame station is not completely same duing the different solar eclipse; and ICF isnot as lower as Predicted. So, it is thought that dynamics may play a more important role in low latitude region than photochemistry related directly to the solarradiation.
