| Popis: | International audience; In this paper a combination of magnetic records with coherent and incoherent radar data at aurorai and middle latitudes (STARE and Saint-Santin) allows a quantitative analysis of the latitudinal profile of the convection electric field. This latitudinal profile is compared with the predictions of the semi-analytical convection model of Senior and Blanc. The aurorai conductivities used in this model are deduced from comparison of the STARE electric field and the magnetic disturbance. Once this normalization is performed, a good agreement is found between the experimental and theoretical electric field profiles. |
