Research

Research Topics, Overview of the research

• Research Topics

  Substorm, Auroral Breakup, Geomagnetically Induced Current, Magnetic Storms, Ring Current, and Radiation Belt

• Overview of the research

  Magnetic storms are one of the largest phenomena that occur in the near-earth space. The magnetic storms are characterized by the ring current. By conducting empirical research based on simulation and observation, I am investigating the magnetic storms and auroras from the view point of the ring current and its coupling to the ionosphere.
