| Zusammenfassung |
| Lidar observations of Rayleigh backscatter
and temperature profiles measured by ozonesondes have been used to investigate
gravity waves in the upper and lower stratosphere, respectively, over
Aberystwyth (52.4°N, 4.1°W). Both data sets have been used to investigate the
vertical wavenumber spectrum of the wave field at high wavenumbers. Similar
analytic techniques applied to each data set enable direct comparison of the
spectra. The possibility of laminar structures generated by differential
advection contaminating gravity-wave fields deduced from temperature and/or
density measurement is discussed and the behaviour of the wave-field mean
potential energy reveals a seasonal cycle throughout the stratosphere with a
late winter maximum and a summer minimum. |
