Formation of a Ring-Shaped Region of Increased Electron Temperature in the Subauroral Ionosphere in Winter

The results of numerical simulations of the electron temperature (Te) are compared with measurement data provided by the CHAMP satellite to show the possibility of the formation of a ring-shaped region of temperature increase in the subauroral ionosphere surrounding the auroral oval in the range of 04–07 h (UT) when the high-latitude ionosphere is on the night (shaded) side.
