Abstract
Results of joint ground-based measurements of vertical structures of ozone and temperatures with the use microwave and lidar technical equipment during stratospheric warming are presented. During winter warming (December 2012 – January 2013) appreciable variations of ozone concentration and temperature in the middle atmosphere are registered. Changes of ozone concentration at height levels from 25 to 60 km increased by 1.5–2 times, the amplitude of their oscillations thus has considerably increased. The peak of a positive deviation of temperature from its monthly average value reached 70 K at a height of 30 km. Daily ozone oscillations at a height of 60 km, connected with sunset and sunrise, were about 30%.
