| Abstract | Rare and sporadic events, caused by unusual conditions in the MLT region may occur such as the sporadic metal layers, observed by lidars, and the more recently detected sharp front in the nightglow emissions imaged with CCD all sky cameras. Few events of this latter kind have been reported in the literature and no simultaneous occurrence of both. In this work, we report the observation of a sporadic sodium layer measured by lidar in São José dos Campos, Brazil (22.5øS, 46øW)on the night of July 13-14, 1999 which was followed by a rare "wall" event observed at Cachoeira Paulista (CP)(23øS, 45øW)in the OH NIR and OI5577 by a CCD imager, and zenith tilting filter photometers. The wind field was also observed by a SkiYmet meteor radar system also operated at CP. At around 23:45 the sodium layer had an abrupt change in its shape. At the same time unusual situation also had occurred in the airglow data taken in CP both with the imager and with the zenith photometer. A sequence of all sky images for the OI557.7 nm and OH NIR showed very clear lines dividing the sky into bright and dark areas, with the first propagating from the NE to SW at 70 m/s and the second propagating to NNE. Zenith photometer also showed a rapid decrease of the OH(6,2)intensity at around 23:45 and a very large increase in the rotational temperature of O2(0,1)(at 94 km)from 23:00 to 24:00 (40 K). The meridional and zonal wind structure measured by the meteorradar in CP showed that from 21:00 to 01:00 a wind shear was present both in the meridional and zonal winds with the phase propagating from 97 to 80 km during this time which were very well correlated with the vertical displacement of the sporadic peak. Large-amplitude gravity wave was also detected. The temperature enhancement above 90 km could be responsible for the sodium density increase and also for the set up of the conditions for the airglow events. |
