| Zusammenfassung |
| Global Positioning System (GPS) radio occultation (RO) is a well-established technique for obtaining
global gravity wave (GW) information. RO uses GPS signals received by low
Earth-orbiting satellites for atmospheric limb sounding. Temperature profiles
are derived with high vertical resolution and provide a global coverage under
any weather conditions, offering the possibility of global monitoring of the
vertical temperature structure and atmospheric wave parameters. The six-satellite constellation COSMIC/FORMOSAT-3 delivers approximately 2000
temperature profiles daily. In this study, we use a method to obtain global
distributions of horizontal gravity wave wavelengths, to be applied in the
determination of the vertical flux of horizontal momentum transported by
gravity waves. Here, a method for the determination of the real horizontal
wavelength from three vertical profiles is applied to the COSMIC data.
The horizontal and vertical wavelength, the specific potential energy
(Ep), and the vertical flux of horizontal momentum (MF) are
calculated and their global distribution is discussed. |
