Abstract: The possibility of a relationship between the quasi-bicentennial temperature variation in the Northern Hemisphere and the solar cycle of Suess was investigated. Linear and nonlinear correlation coefficients between quasi-bicentennial cycles in temperature and solar activity were calculated. Nonlinear correlation coefficients were calculated based on mutual information estimates. It turned out that in most cases, the significance of nonlinear correlation is significantly higher than that of linear correlation. This result indicates that the relationship between quasi-bicentennial cycles in Northern Hemisphere temperature and solar activity may be nonlinear.
