| 英文摘要 | In order to study the correlation distance S of the ionospheric day-to-day variability, especially the diurnal and seasonal variation of S and how it changes with solar and geomagnetic activities, we adopted the ionospheric F-2-layer peak electron density, NmF2, obtained from 22 European stations. We first used an exponential function to describe how the correlation coefficient R of the ionospheric day-to-day variability between any two stations changes with its distance d, and then from that computed the correlation distance S. We then studied the diurnal variation of correlation distance S versus universal time for different seasons (spring, summer, autumn and winter), different geomagnetic activity levels ( quiet and disturbed), and different solar activity levels (low, medium and high). We found that: (1) The ranges of S are confined from 400 up to 1600 km; (2) The values of S are larger at daytime than nighttime; (3) There are seasonal trends of S, generally, the S values are largest in summer, smallest in winter, and the differences between it in spring and autumn are quite small. (4) When the geomagnetic activity level is disturbed, the S values are larger than when quiet. (5) From sundown to noon of next day the S values are distinctly smaller when the solar activity level is low, than those when the solar activity level is medium or high, but from noon to just before sundown, the S values change little with the solar activity levels. |
