Solar Wind Plasma Temperature Influence on Earth’s Magnetic Field Variation During 2024

Abstract

Solar wind parameters play a key role in controlling the interaction between the sun plasma and the Earth's magnetic field (the Earth's magnetosphere). One of these parameters is the temperature (SWT) of the solar wind plasma, which is considered a highly important indicator of the dynamic conditions in interplanetary space. In this study, we examined the effect of the solar wind plasma temperature on the intensity of the Earth's magnetic field in year 2024. We analyzed solar wind plasma temperature data along with measurements of Earth's magnetic field intensity to understand their relationship and the extent to which solar wind temperature affects Earth's magnetism. From the results, we found that an increase or rise in solar wind plasma temperature is usually associated with an increase in solar wind pressure and stronger interactions with Earth's magnetosphere, which causes disturbances in Earth's magnetism. That’s mean, the relationship between them is linear, meaning that when the solar wind temperature increases, the magnetic field intensity also increases, which is logical and expected because the magnetosphere acts as a shield protecting the Earth from the hazards of solar wind plasma. This study provides an understanding of the extent of the role of solar wind plasma parameters, particularly its temperature, in improving the understanding of space dynamics under solar activity conditions observed during the year 2024.
