A model of the ionosphere and plasmasphere with allowance for the anisotropy of charged-particle temperatures is developed on the basis of numerical integration along a geomagnetic field line of the system of equations of the anisotropic hydrodynamics of a partially ionized plasma. The model made it possible to determine the role of possible mechanisms for the formation of the anisotropy of plasma temperatures and to quantitatively describe the space-time distribution of this anisotropy. It is shown that the nonuniform transfer of longitudinal and transverse energy in the geomagnetic field leads to the formation of temperature anisotropy at plasmaspheric levels in partially emptied flux tubes with L not less than approximately 3. Longitudinal electric fields of 10 to the -9th V/cm play a highly significant role in the anisotropization of thermal electrons not only in the plasmasphere but also in the upper ionosphere.
