摘要。本研究试图证明在地磁风暴期间电离层f1区日间电离的变化。利用欧洲几个中纬度和低纬度观测站的现有数据以及包括一系列季节和太阳活动水平的一系列地磁风暴，对f1区域进行了探索。分析结果表明，f1区对地磁风暴的响应存在系统的季节差异和部分纬度差异。在中纬度较高的地方，f1区域的响应模式，即电子密度的降低，并不取决于f2区域的响应类型和太阳活动。本文对这些发现作了简要的解释。关键字。电离层（电离层扰动；中纬度电离层）
Abstract. This study attempts to demonstrate changes in the ionospheric F1-region daytime ionization during geomagnetic storms. The F1-region is explored using available data from several European middle latitude and lower latitude observatories and a set of geomagnetic storms encompassing a range of seasons and solar activity levels. The results of analysis suggest systematic seasonal and partly latitudinal differences in the F1-region response to geomagnetic storm. The pattern of the response of the F1-region at higher middle latitudes, a decrease in electron density, does not depend on the type of response of the F2-region and on solar activity. A brief interpretation of these findings is presented. Key words. Ionosphere (ionospheric disturbances; mid-latitude ionosphere)
