| Two case studies of large scale particle transport, using a test particle approach in Earth's magnetosphere, are presented. The first case considers different possible entry paths of solar wind plasma into the magnetosphere for quiet geomagnetic conditions. Solar wind plasma is captured in the high latitude cusp region and subsequently enters the magnetosphere. Most of the penetrating particles flow into the tail. Nevertheless, some particles drift into the inner magnetosphere and populate the boundary layers and plasma sheet. Other particles are trapped around Earth and produce a ring current-like region. The second case considered focuses on electron response to a transient process triggered by solar wind dynamic pressure pulse. The results illustrate electron adiabatic injections and corresponding energy flux enhancements, and suggest that the induced earthward E x B drift has an effect on particle transport and energization during the dipolarization-like process associated with solar wind pressure pulse. |
