Highlights The relation between the QBO and SSN is investigated with a multiple regression model. There is a positive relation between QBO- and SSN for solar maximum. There is a negative relation between QBO- and SSN for solar minimum. We observed that the variation of QBO up to maximum 16m/s is due to SSN.
Abstract In this study, the relationship between the monthly mean values of the Quasi Biennial Oscillation (QBO) measured at 10hPa and 70hPa altitudes and Sunspot Number (SSN) for solar maxima and solar minima conditions is analyzed. Before applying the model for the statistical analysis of the study, the stationary of the variables is investigated by using the unit root test. Existence of a long-term relationship between the variables is also investigated by using the co-integration test. Positive and negative relationships between SSN and QBO obtained for 10hPa and 70hPa are observed for the solar maxima and the solar minima, respectively. The explainable effects of the SSN on the QBO at 10hPa altitude are greater than those at 70hPa. When the calculated coefficients are analyzed, it is observed that the variation of QBO up to 16m/s is due to SSN. The rest of at least 34m/s are seen to be based on the other variables.
