“…To examine the effect of temperature, correlations of temperature and solar UV variations have been separately analyzed and incorporated into a physical model in some studies [Hood, 1986;Keating et al, 1985]. With such a model the negative time lag of ozone relative to solar UV flux (ozone leading solar UV) found in the upper stratosphere could be explained as the result of interactions of ozone, temperature and solar UV flux [Hood, 1986;Hood and Jirikowic, 1991].…”

“…The response of stratospheric ozone to solar UV flux changes occurring on the timescale of the 27-day solar rotation period has been extensively studied since satellite data became available [Gille et al, 1984;Hood, 1984;Keating et al, 1985;Chandra, 1986;Hood, 1986;Lean, 1987;Hood and Zhou, 1998]. Statistical and spectral analyses, including cross-correlation analyses, are useful mathematical tools for such studies.…”

Abstract. Observational detection of upper stratospheric ozone responses to 27-day solar ultraviolet (UV) variations is often inhibited by larger, dynamically induced ozone variations, which result mainly from the temperature dependence of reaction rates controlling the ozone balance. Here we show that partial correlation coefficients of solar UV and tropical upper stratospheric ozone (1-5 hPa) with the temperature effect removed are larger (07-0.8) than are total correlation coefficients of ozone and solar UV (0.4-0.6). The phase lag of ozone relative to solar UV is also increased, and the maximum ozone-UV correlation is obtained at higher altitudes, as compared with correlation analyses using ozone and solar UV data alone. Assuming that temperature variations are not forced by solar UV variations, the ozone sensitivity to solar UV and temperature can be calculated using a linear multiple regression model. The ozone sensitivity to solar UV is generally independent of time periods used for the analysis. However, the magnitude of the ozone sensitivity to temperature at 1-2 hPa increased significantly from solar cycle 21 to solar cycle 22, possibly reflecting long-term changes in the composition of the upper stratosphere.

“…Real information about UV (Heath, 1980) was used to estimate the amplitude of the 27-days tide which looks like Rossby wave gave the results closer to statistical analysis . The simultaneous observation of ozone mixing ratio distribution together with UV flux variations due to solar rotation were carried out (Hood, 1984;Gille et al, 1985;Keating et al, 1985) and revealed 27-days and 13.5-days periodicity in ozone accompanied by a similar oscillation in the 205 nm range of solar UV-radiation and temperature (Keating et al, 1987). Lidar measurements has shown the temperature changes on the time scale of the sun's rotation (Keckhut and Chanin, 1992).…”

Tidal theory analysis, 2-D numerical modelling of a large-scale planetary transient waves excitation by external forcing and data analysis has revealed the possibility for resonant response of the middle atmosphere. Such reaction has a nature of a barotropic motions and looks like atmospheric Rossby waves. Two types of forcing has been realised in model runs: solar UV 27-day variability (from above) and tropospheric periodical disturbances (from below). The results of model calculations has shown that the middle atmosphere of the Earth has its own periods and may be excited by a weak signal. Some of these periods are near to solar rotation period and others to the meteorological periodicities (5-7 and 12-14 days). The amplitudes of the waves in terms of geopotential heights increase from below to the higher levels and reach the quantities of about 50-80 gpm in the lower mesosphere. A special 2-D statistical method for transient waves detecting has shown that the real waves with similar spatial structure and character periods are really exist in the troposphere and lower stratosphere.

“…Seele and Hartogh, 1999;Körner and Sonnemann, 2001;. Model calculations predict only a relatively slight dependence of the ozone concentration on temperature (according to the dependence of the reaction rates on temperature), water vapor or even on chlorine when it varies in natural borders (Frederick, 1980;Rusch et al, 1983;Solomon et al, 1983;Keating et al, 1985;Fichtelmann and Sonnemann, 1989).…”

Abstract. Ozone measurements taken with a ground based microwave instrument at Lindau (51.66 • N, 10.13 • E) over some years showed strong ozone decrease events within the stratopause region, particularly during the winter half-year. These events are characterized by a marked drop of the ozone mixing ratio from two to three ppmv to less than half a ppmv in extreme cases. Simultaneous water vapor measurements at the same place, also carried out by a microwave instrument, showed a strong increase of its mixing ratio and the temperature was also enhanced during these episodes. The theoretical analysis brought evidence that these events result from a positive feedback in the complex radiatively-chemical system between the ozone column density and the ozone dissociation rate.
