Some results of observation of spatial inhomogeneities in hydroxyl emission

Preliminary results of observation of spatial inhomogeneities in OH emission originating during passing of internal gravity waves are given. Data were obtained with the use of large-aperture infrared CCD-camera installed in Geophysical Observatory of ISTP SB RAS. We also present some morphological characteristics of wave disturbances such as types of registered waves, frequency of their occurrence, dominant direction of propagation, etc.
