| Abstract: | The effect of upward parallel electric field observed along the auroral field lines on the Alfven wave model of magnetosphere-ionosphere coupling is examined through the modification of the particle thermal velocity parallel to ambient magnetic field. Effects of electron beam generated in the plasma-sheet region and impinging the ionosphere, and temperature anisotropy of the acceleration region have been also considered. The enhancement of the auroral upward field aligned current in the region of parallel electric field is predicted as observed by S3-3 satellite and polar satellite data. |
