A synchronized solar dynamo model and its consistency with climate data

We examine a remarkable consistency of the power spectrum of paleoclimatic varved sediment data from Lake Lisan [1] with that of a novel solar dynamo model that is doubly synchronized by tidal effects and the revolution of the Sun around the barycenter of the solar system [2,3]. We support and specify the latter model by quantifying the tidal excitation of magneto-Rossby waves [4] at the solar tachocline and by estimating the effects of spin-orbit coupling. Typical time series resulting from this dynamo model are then utilized in a double regression of solar and anthropogenic influences on the global temperature of the past 170 years in order to quantify various climate sensitivities [5].  [1] S.
