Investigating the Link between Space-Weather Parameters and Forbush Decrease

The link between space-weather parameters and Forbush decrease has been investigated. The aim was to determine the relationship between space-weather parameters and forbush decrease. Daily cosmic ray counts from MGDN station for 2010-2015 were used to achieve this aim. Solar wind speed (SWS) and interplanetary magnetic field (IMF) intensity were equally used as space-weather parameters. The semi-automated method of FD detection was deployed. This method generated 1104 FDs for the MGDN station within the years under study. A correlation and regression between FDs and space-weather parameters (SWS and IMF) were further tested. The results of the correlation and regression are statistically significant. The implications of the present space-weather data on FDs are highlighted.
