The interannual variations in total ozone are studied using revised Dobson total ozone records (1961--1990) from 17 stations located within the latitude band 30 ¿N--60 ¿N. To obtain the quasi-biennial oscillation (QBO), El Ni¿o-Southern Oscillation (ENSO), and 11-year solar cycle manifestation in the ''northern temperate'' total ozone data, various multiple regresion models are constructed by the least squares fitting to the observed ozone. The statistical relationships between the selected indices of the atmospheric variabilities and total ozone are described in the linear and nonlinear regression models. Nonlinear relationships to the predictor variables are found. That is, the total ozone variations are statistically modeled by nonlinear terms accounting for the coupling between QBO and ENSO, QBO and solar activity, and ENSO and solar activity. It is suggested that large reduction of total ozone values over the ''northern temperate'' region occurs in cold season when a strong ENSO warm event meets the west phase of the QBO during the period of high solar activity. ¿ American Geophysical Union 1994
