| 英文摘要 | The data of the estimated power input (EPI) of auroral particles from NOAA/POES (Polar orbiting environmental satellite) for some 30 years have been analyzed. The annual variation of EPI shows equinox peaks, and an asymmetric activity with a higher peak in the winter-hemisphere than in the summer-hemisphere. The variation tendencies of the EPI generally coincide with aa, AE and D-st indices. Studies on the correlations of the hourly average of EPI, Pa, with AE and D-st indices show a correlation coefficient r=0.76 of Pa and AE and r=-0.55 of Pa and D-st. The EPIs for north and south polar regions, NPa and SPa, show a north-south asymmetry with a higher correlation of SPa and AE (or D,,). Time delays of EPI with respect to magnetic indices are examined, the maximum correlation coefficient of Pa with AE (r=0.78) occurs when the time delay tau = 0, suggesting a synchronism of auroral electrojet and auroral precipitating particles, while tau = 1 similar to 2 hours, the correlation coefficient of Pa with D,, is maximum (r=0.57), suggesting that the activity of auroral particle precipitation may influence the ring current to some extent. |
