| 英文摘要 | The empirical orthogonal function (EOF) analysis has been applied to studying the ionospheric electron density profiles between 160 and 700 km, which is based on the data obtained from the incoherent scatter radar at Millstone Hill from February 1976 to April 2006. The mean electron density profile and the first three terms of EOF series with the mean term are fitted by Chapman-alpha function respectively. The results reveal that the first term of EOF series of the ionospheric electron density profiles mainly controls the ionospheric F-2 peak density NmF2, the second controls both the F-2 peak height h(m)F(2) and the effective scale height H-m, and the third controls the effective scale height H-m. In addition, we have analyzed the diurnal, seasonal and solar activity variations of the corresponding coefficients of the EOF terms. These variations represent the climatic characteristics of NmF2, h(m)F(2) and H-m, such as the ionospheric winter anomaly and semiannual anomaly. EOF series converge rapidly in analyzing the electron density profiles, and the first few terms can represent the main characteristics. So we can use EOF analysis to extract the main distributional characteristics as well as the diurnal and climatic variation characteristics of the electron density profiles, which can be used to build the empirical model for further study. |
