Abstract

This paper examines vertical temperature profiles of the middle atmosphere at heights from 25 to 60 km obtained with Rayleigh lidar near Yakutsk during the sudden stratospheric warming (SSW) of major type in January, 2010. To study manifestations of wave processes in the temperature profiles the wavelet methods have been used. The continuous wavelet transformation has given a complete review of the temporal and spatial development of wave regime of the middle atmosphere. Thus vertical wavelengths as afunction depending on a height have been obtained , then so that an attempt to reveal corresponding wavelengths which caused SSW on the critical level in breaking.
