- Аннотация: We made a statistical study of how the variation of the solar wind dynamic pressure and the IMF Bz component do affect the geomagnetic field and the plasma pressure in the inner magnetosphere using the data from THEMIS mission. Both the solar wind dynamic pressure and IMF Bz component are the key input parameters for the majority of geomagnetic field models and their influence on the inner magnetosphere dynamics is well studied. Nonetheless, we reached to establish some new important features. In particular, we could obtain a combination of the input parameters for which a minimum of the geomagnetic field located nearly 12 Earth Radii can be clearly observed for the dawn, night, and dusk MLT. We also found how the inner magnetosphere pressure grows with the solar wind dynamic pressure for different values of Bz. These statistical studies were compared with the radial pressure profiles, obtained using DMSP mission satellites. The results obtained contribute to the further development of geomagnetic field models and give new insides about the physics of geomagnetic substorms.
