| Zusammenfassung |
| The Joule heating and ion drag effects are considered as important factors in the neutral wind dynamics in the polar E-region. However, quantitative evaluations for these effects are insufficient for correct understanding, particularly, in the lower E-region (100-110 km heights) where the anomalous heating effect, related with the electron Pedersen currents, can occur during the intense electric field. In the present study, using EISCAT Svalbard radar data, we have investigated, for the first time, the normal and anomalous heating effects to the neutral wind acceleration in the lower E-region. |
