The atmospheric effect relating with 11-year solar cycle is investigated with a focus on stratospheric ozone variation and its correlation with temperature variation. A three-dimensional chemical transport model forced by a general circulation model has been integrated, where the dynamical field is assimilated into reanalysis data every time-step, for two different experiments. The photolysis rates of one experiment are calculated through an observational time series of the solar ultraviolet irradiance, and for the other experiment the averaged irradiance is used. Multiple regression analyses of the model results for 22 years, from 1978 to 2000, have revealed that solar signals of ozone are related to meteorological (temperature and transport) changes not only bellow the middle stratosphere but also in the upper stratosphere where photochemical influence is dominant. The photochemical effect almost disappears below 20 hPa, indicating that the meteorological changes solely produce the solar signals of ozone below the middle stratosphere.
