摘要

We present the dependence of the magnetosonic wave amplitudes both outside and inside the plasmapause on the solar wind and AE index using Van Allen Probe-A spacecraft during the time period of 1 October 2012 to 31 December 2015, based on a correlation and regression analysis. Solar wind parameters considered are the southward interplanetary magnetic field (IMF B_S), solar wind number density (N_(SW)), and bulk speed (V_(SW)). We find that the wave amplitudes outside (inside) the plasmapause are well correlated with the preceding AE, IMF B_S, and N_(SW) with time delays, each corresponding to 2-3 h (3-4 h), 4-5 h (3-4 h), and 2-3 h (8-9 h), while the correlation with V_(SW) is ambiguous both inside and outside the plasmapause. As measured by the correlation coefficient, the IMF B_S is the most influential solar wind parameter that affects the dayside wave amplitudes both outside and inside the plasmapause, while N_(SW) contributes to enhancing the dusksidewaves outside the plasmapause. The AE effect on wave amplitudes is comparable to that of IMF B_S. More interestingly, regression with time histories of the solar wind parameters and the AE index preceding the wave measurements outside the plasmapause shows significant dependence on the IMF B_S, N_(SW), and AE: the region of peak coefficients is changed with time delay for IMF B_S and AE, while isolated peaks around duskside remain gradually decrease with time for N_(SW). In addition, the regression with magnetosonic waves inside the plasmapause shows high coefficients around prenoon sector with preceding IMF B_S and V_(SW).
