Scientific paper

In-situ plasma density measurements from the CHAMP satellite between about 350-420 km altitude are used to delineate intra-annual variations in the longitudinal structure of the F-region ionosphere. It is shown that the longitude structures during mid-day local times are dominated by the space-based longitudinal wavenumbers k s = 2, 4 and 3 in January, July and December, respectively. These conform to the same dominating k s -values characterizing solar thermal tide zonal winds in the dynamo region, namely the westward-propagating semidiurnal tide with planetary-fixed zonal wavenumber s = 4 (SW4), and the eastward-propagating diurnal tides with s = -3 (DE3) and s = -2 (DE2), respectively. DE3 is the dominating tide during the other months. The results presented indicate that nonmigrating tides other than DE3 may significantly impact the longitudinal structure of the low-latitude ionosphere during certain months.
