Аннотация:Possible physical interpretation of connection between solar cycle length (SCL) and temperature anomalies are discussed. It is shown that as a rule shorter cycles are the more intensive ones. During more intensive cycles one can observe solar radiation increase and decrease of galactic cosmic ray influence on cloud formation. Both, direct and non-direct effects of solar activity are additive and lead to temperature enhancement. So, the shorter cycles could be the warmer ones. It is demonstrated that temperature response to cycle length changes are different for periods 1705-1810 and 1900-1990, and equal similar to0.03 degrees /yr and 0.4 degrees /yr correspondingly, and practically absent for period 1810-1890. SCL-parameter reflects only tendency: shorter (and more powerful) cycles are connected to warmer climate and could hardly be used for numerical estimates of solar influence on the climate.
