Abstract

We share our research on the effects of geomagnetic storms on Earth's climate throughout the solar cycle. We use the Kp index value from ACE and several other observatories to comprehend the impact of the geomagnetic storm in this instance. A geomagnetic storm is indicated by a value of 5 or higher on the K-index, which uses an integer between 0 and 9 to quantify disturbances in the horizontal component of the Earth's magnetic field. It is calculated using the highest horizontal component variations that a magnetometer records during a three-hour period. The NOAA G-scale was created with the intention of directly corresponding to the importance of geomagnetic storm impacts. The magnetosphere is first compressed by the rise in solar wind pressure. The Dst index determines the worldwide averaged change in the horizontal portion of the Earth's magnetic field near the magnetic equator using information from a limited number of magnetometer locations. Consideration is given to a potential mechanism wherein solar flare ionising radiation causes earthquakes. Dst is reported almost instantly after being computed once every hour. Dst is between +20 and −20 nano-Tesla (nT) at quiet periods.
