Study of Solar Wind Influences on Earth’s Magnetic Field

In this paper, we studied the impact of solar activity, especially proton density, He++/H+ ratio and temperature of solar wind, on the geomagnetic field and thereby on earth’s climate. The verified data of these indices are collected from the official websites: wdc.kugi.kyoto-u.ac.jp and www.srl.caltech.edu/ace . Using the data values, both the indices are analyzed and studied to explore the link between solar activity and geomagnetic field. The magnetic field is irregular with negative and positive peaks and at the same time it shows the uniformity with the irregularities of solar wind plasma parameters. It has been observed that solar wind plasma has a significant influence on the intensity of magnetic field of earth and this correlation can be used for weather forecasts and climatic studies in the future.
