Abstract: The purpose of this research is to look at the relationship between geomagnetic activity indices (Dst and Kp inex), solar wind parameters (i.e. solar wind speed V, plasma proton temperature and plasma flow pressure), interplanetary field parameters (B and Bz) and with solar wind speed product functions (i.e. V.B, V.B2, V.Bz and V.Bz2) in different phases of solar cycle 22 (1986-1995). For the investigation, we used Chree analysis by the superposed epoch method. When compared to interplanetary field parameters and solar wind parameters, the results of this study revealed that solar wind speed product functions are more geo-effective. We have found that the Kp index is highly correlated with solar wind parameter (i.e. plasma flow pressure), interplanetary field parameters and their product functions in comparison to the Dst index, which indicates that the Kp index is a good indicator of geomagnetic storm. We also observed that geomagnetic indices i.e. Dst index and Kp index are tightly correlated to each other. We have performed the time delay analysis by the method of correlation coefficient between the extreme value of geomagnetic activity indices, solar wind parameters, interplanetary field parameters and their product functions and observed a time delay of 0 hours for most of the years of solar cycle 22, while for some years, a time delay of 5-20 hours was found between the extreme value of geomagnetic activity indices, solar wind parameters, interplanetary field parameters and their product functions.
Keywords Solar wind parameters, interplanetary field parameters, geomagnetic activity indices.
