| Zusammenfassung |
| We present the characteristics of small-scale (<100 km) gravity waves in
the equatorial mesopause region derived from OH airglow imaging observations
at Kototabang (100.3° E, 0.2° S), Indonesia, from 2002 to 2005.
We adopted a method that could automatically detect gravity waves in the
airglow images using two-dimensional cross power spectra of gravity waves.
The propagation directions of the waves were likely controlled by zonal
filtering due to stratospheric mean winds that show a quasi-biennial
oscillation (QBO) and the presence of many wave sources in the troposphere. |
