Study Of Coronal Mass Ejections Associated With Radio Burst Related Geomagnetic Storms With Solar Wind Disturbances
Journal Title: International Journal of Innovative Research & Growth - Year 2018, Vol 7, Issue 4
Abstract
Abstract In this manuscript we have studied radio bursts (RB) related geomagnetic storms (GMS) Dst ≤ -90nT for the period 1997 to 2012. From the data analysis, we have found total number of radio bursts related geomagnetic storms are 42. Out these 37(88.09%) are found to be associated with coronal mass ejections (CMEs). Out of 37, 25 (67.57%) are related to the halo coronal mass ejections, 12(32.43%) are found to be associated with partial halo coronal mass ejection. Positive co-relation with co-relation coefficient 0.28 has been found between magnitude of radio bursts related geomagnetic storms and speed of associated coronal mass ejections. Further we have concluded that associated CMEs are closely related to jump in solar wind plasma density (JSWD) and jump in solar wind plasma velocity (JSWV). Positive co-relation has been found between speed of CMEs and peak value of associated JSWD events with co-relation co-efficient 0.16, 0.26 between speed of CMEs and magnitude of associated JSWD events, 0.44 between speed of CMEs and peak value of associated JSWV events, 0.26 between speed of CMEs and magnitude of associated JSWV events.
