The aim is to analyze the time variation of the relationships between geographical factors and precipitation during summer. Various candidate geographical predictors are evaluated in the stepwise regression models for summer precipitation. The most significant for precipitation regression models have been selected using PCA and STW approaches. Multivariate regression precipitation models are generated for each year, and each overlapping decade from 1971 to 2003 using them as predictors. Linear trends in regression coefficients are estimated using a least-squares regression to detect the possible changes in relationships between summer precipitation and geographical variables. No significant trend has been found during 1971-2003. Therefore, the relationships between these significant predictors and precipitation are stable in time.
