A theoretical model for generation of a pair of region 1 and region 2 field-aligned currents (FACs) is presented. From the observed pattern of auroras, the existence of a hot plasma torus (HPT) in the magnetosphere can be assumed. An HPT is defined as a hot plasma contained in the magnetic shell which is connected to two ovals of diffuse auroras on the northern and southern polar ionospheres. It is porposed that region 1/region 2 FACs can be generated as a result of natural distortion of the HPT under the influence of the solar wind convection.
