The disturbances in the geomagnetic fields are caused by fluctuations in the solar wind impinging on the earth. In the present study the identification of 214 geomagnetic storms associated with disturbance storm time (Dst) decrease of more than -50nT to -300nT, have been made, which are observed during 2007-2016, the time period spanning over solar cycle 23. The degree of the equatorial magnetic field deviation, the measure of the magnitude of geomagnetic storms is usually given by the Dst index. The study is made statistically between the Dst strength (used as an indicator of the geomagnetic activity) and the peak value obtained by solar wind plasma parameters and IMF B as well as its components. We have used the hourly values of Dst index and the wind measurements taken by various satellites. This is the hourly average of the deviations of the H (horizontal) component of the magnetic field measured by several ground stations in mid-to low latitudes.
