论文摘要
我们使用$δ$ sym-h在地磁风暴的主要阶段捕获Sym-H指数的变化。我们将巨大的地磁风暴定义为$δ$ sym -h $ \ le $ -200 nt的风暴。在分析了太阳风未掩盖的数据之后，我们确定了11种暴风雨在太阳周期中发生。我们计算了向南的行星际磁场组件I（b $ _s $）的时间积分，太阳能电力电场I（E $ _y $），E $ _y $ $ $ _y $ $ _y $和SOLAR WIND DYDARITS的组合在A.Y $ _y $ i Dynece a a a a a a a a a a a a a e a a a a a风暴中的综合点数（ The strength of the correlation coefficient (CC) between $Δ$SYM-H and each of the three integrals I(B$_s$) (CC = 0.74), I(E$_y$) (CC = 0.85), and I(Q) (CC = 0.94) suggests that Q, which encompasses both the solar wind electric field and the solar wind dynamic pressure, is the main driving factor that determines the intensity of a great地磁风暴。结果还表明，B $ _s $对巨大的地磁风暴强度的影响要比太阳风速和在相关的大地磁风暴的主要阶段的动态压力的影响要高得多。还讨论了如何根据太阳风参数估计极端地磁风暴的强度。
We use $Δ$SYM-H to capture the variation in the SYM-H index during the main phase of a geomagnetic storm. We define great geomagnetic storms as those with $Δ$SYM-H $\le$ -200 nT. After analyzing the data that were not obscured by solar winds, we determined that 11 such storms occurred during solar cycle 23. We calculated time integrals for the southward interplanetary magnetic field component I(B$_s$), the solar wind electric field I(E$_y$), and a combination of E$_y$ and the solar wind dynamic pressure I(Q) during the main phase of a great geomagnetic storm. The strength of the correlation coefficient (CC) between $Δ$SYM-H and each of the three integrals I(B$_s$) (CC = 0.74), I(E$_y$) (CC = 0.85), and I(Q) (CC = 0.94) suggests that Q, which encompasses both the solar wind electric field and the solar wind dynamic pressure, is the main driving factor that determines the intensity of a great geomagnetic storm. The results also suggest that the impact of B$_s$ on the great geomagnetic storm intensity is much more significant than that of the solar wind speed and the dynamic pressure during the main phase of associated great geomagnetic storm. How to estimate the intensity of an extreme geomagnetic storm based on solar wind parameters is also discussed.
