Documentation of the solar activity variations and it's influence on climate

Dimitris Poulos


The four planets that influence the most the solar surface through tidal forcing seem to affect the Earth climate. A simple two cosine model with periods 251 years, of the seasonality of the Earth – Venus syzygies, and 265.4 years, of the combined syzygies of Jupiter and Mercury with Earth when Earth is in synod with Venus, fits well the Northern Hemisphere temperatures of the last 1000 years as reconstructed by Jones et al (1998). The physical mechanism proposed is that planetary gravitational forces drive solar activity that in turn drives temperature variations in earth. The sun is in a boundary balance state at one hand collapsing due to gravity and at the other hand expanding due to fusion, and as such it should be heavily influenced by minimal external forcings such as planetary gravity. Sound waves in the solar mass, created from the planetary movement, are responsible for the formation of solar corona and sun spots. The Earth-Venus 251 year resonance is resonant to a near surface solar layer's thermal natural frequency that “explodes” to form solar wind. The calculated solar wind properties match the observed.
