Abstract
This thesis deals with modeling of major ions outflow in the polar cap at altitudes
higher than 400km. Different ion outflow models are numerical investigated and the pros
and cons of these models are discussed. Observations are crucial for model validations. In
this work we have used Akebono Satellite observations, which showed that between 5000
and 9000km altitudes H+ and 0+ can have higher outflow velocities in the day-side region
that on the night-side [Abe and et al,1993a, 1993b]. classical polar wind model cannot
explain fully these observations [Schunk and etal,1981, 1988]. In this thesis, in order to
address the observation we discuss hydrodynamic model by considering driven shock wave.
Most of observed properties are well explained by using this model
