摘要
我们分析了太阳周期 23 和 24 期间探测到的与磁云有关的地磁暴以及太阳风等离子体参数的扰动。我们发现,所有与磁云相关的地磁暴都伴随着太阳风等离子体参数的扰动。与磁云相关的地磁暴的大小与太阳风等离子体参数太阳风等离子体速度(SWPV)、太阳风等离子体密度(SWPD)、太阳风等离子体温度(SWPT)、行星际磁场(IMFB)和行星际磁场南向分量(IMFBz)的扰动峰值密切相关。与 MC 有关的地磁暴的大小与行星际磁场的相关扰动的峰值之间存在很大的正相关性,相关系数为 0.60;与 MC 有关的地磁暴的大小与 IMFBz 的相关扰动的峰值之间存在 0.67 的正相关性。此外,在太阳风等离子体温度中,与 MC 有关的 GMS 的大小与相关扰动的峰值之间呈正相关(相关系数为 0.54);在太阳风等离子体速度中,与 MC 有关的 GMS 的大小与相关扰动的峰值之间呈正相关(相关系数为 0.40);在太阳风等离子体密度中,与 MC 有关的地磁暴的大小与相关扰动的峰值之间呈正相关(相关系数为 0.27)。
Solar Wind Plasma Parameters in Relation with Good Quality Magnetic Cloud Related Geomagnetic Storms
We have analyzed magnetic cloud related geomagnetic storms detected during the period of solar cycle 23 and 24 with disturbances in solar wind plasma parameters. We have observed that all the MC related geomagnetic storms are accompanying with disturbances in solar wind plasma parameters. The magnitude of magnetic cloud related geomagnetic storms is soundly correlated with peak disturbances values of solar wind plasma parameters solar wind plasma velocity (SWPV), solar wind plasma density (SWPD), solar wind plasma temperature (SWPT), interplanetary magnetic fields (IMFB) and southward component of interplanetary magnetic fields (IMFBz). Large positive correlation with correlation coefficient 0.60 have found between magnitude of MC related GMS and peak value of related disturbances in IMFB and 0.67 between magnitude of MC related geomagnetic storms and peak value of associated disturbances in IMFBz. Additionally positive correlations with correlation coefficient 0.54 have been found between magnitude of MC related GMS and peak value of associated disturbances in solar wind plasma temperature ,0.40 between magnitude of MC related GMS and peak value of associated disturbances in solar wind plasma velocity, 0.27 between magnitude of MC related geomagnetic storms and peak value of disturbances in soar wind plasma density.
