Solar activity effects on magnetosphere ionosphre dynamics

Earth's magnetosphere is affected by the Sun's activity. Solar wind and interplanetary magnetic field distore the Earth's magnetic field line, especially southward interplanetary magnetic field changes the structures and dynamics of the magnetosphere. Magnetosphere is thought to be an energy storage mechanism, and the release of the sudden energy from the magnetosphere can lead disturbances like influence of solar wind on Earth. One of the most important mechanisms of the magnetospheric dynamic is substorms. Substorms are outstanding events to understand the respond of the magnetosphere. Momentum transport, energy conversion and dissapation mechanisms give information about the structure and dynamics of the magnetosphere. For this reason, basic Maxwell-Boltzmann-Vlasov and Magnetohydrodynamics equations kinetic theory of the wave are useful tools to understand the nature of these mechanisms mathematically. Alfven waves can be a selectional physical phenomena for us to learn to magnetospheric plasma, in case detailed information is required. Alfven wave structure can be observable through the magnetotail to Earth's Ionosphere. Therefore, changes and dynamics of the plasma can be observed via Alfven waves. Kinetic Alfven waves play an important role related to the wave-particle interaction, particle acceleration and heating process as a low frequency structure. Besides, the kinetic Alfven waves, mirror mode structure and instability are important for the behavior of the central plasma sheet. Observations and analyses were made in application and observations as a part of the dissertation.
