Numerical modeling of behavior of high-energy plasmoid in upper ionosphere Original Research Article

In this paper the numerical investigation of parameters of the plasmoid expanding into rarefied ionosphere and the geomagnetic field are performed. The range of the initial energy change is image and of the mass change is image. These ranges conform to the well-known large-scale geophysical experiments “Argus” and “Starfish”. The first stages of the development of the plasma flow are considered: the radiation-gas-dynamic, the inertial and the braking stage by the geomagnetic field. For this goal a special numerical algorithm is created.
