For more than a decade, derived results from the High Resolution Doppler Imager (HRDI) on UARS have provided an enormous amount of new and invaluable information on the global variability of atmospheric winds. These and other results have given added impetus to theoretical modeling efforts. Until recent years, the large majority of investigations have focused on migrating tides, and now more results on nonmigrating tides have become available. We provide new results for semidiurnal and diurnal nonmigrating tides based on data from HRDI at 95 km. Much of these results have not been obtained before, and they are substantially different from those that have been previously reported. Our amplitudes are usually significantly larger, with more periodicities in both day of year and latitude than results that have previously appeared in the literature. We also find components (up to longitude wave number 3) that are significant and have not been presented before and that traveling components of larger-longitude wave numbers 4, 5, and 6 can reach several m/s in amplitude. We compare our results with earlier results based on HRDI measurements and from selected models. |
