The duration of Solar Cycle 23-24, we look at the relationship between the cosmic-ray intensity (CRI), the density of the interplanetary magnetic field (IMF) and geomagnetic storm activity. We used the superposed method to perform an analysis in order to influence this. On the days when geomagnetic storm GS occurs, there is a brief reduction in CRI, and this drop has a pattern resembling that of the disturbance storm-time index (Dst). Additionally, a drop in the Dst index correlates with an increase in IMF-B. For the time under study, there is no correlation between the sunspot number (SSN) the interplanetary magnetic field (IMF), Kp index, or CRI, but there is a strong anti-correlation between the two. It is found that the IMF is a useful parameter combination for generating a decline across GS and Forbush. we use monthly average on the interplanetary magnetic field (IMF-B), geomagnetic storm (GS) averaged planetary A-index (Ap-index), and sun spot number (SSN) to examine the relationship between cosmic ray intensity (CRI) and these parameters for the period 1996–2019 solar cycle 23&24. In order to determine the correlation between cosmic ray intensity CRI and several solar wind (SW) metrics, GSs, IMF-B, Ap index, and SSN, we use the superposed method of analysis. It has been seen that as IMF B grows, CRI falls. Furthermore, we demonstrate that during the majority of solar cycle 23&24, the CRI decreases in a manner akin to that of disturbance storm time (Dst index). There is a strong and supportive association between the Dst index and the CRI. a comparison of CRI and IMF, the Ap index and CRI have a stronger anti-correlation. There is an improvement between CRI and SSN.
