Interpretation of physical factors responsible for global and regional climatic responses to long-term solar activity variations

The influence of ~200-year solar periodicities (deVries cycle) on climatic parameters has been analyzed for different regions of the Earth. A nonlinear character of the response of the atmosphere-ocean system to solar activity has been experimentally verified. Regions characterized by pronounced positive and negative responses have been found to exist at the Earth's surface. There are also boundary regions with no response or having an unstable character. The locations of boundary regions can vary both in time and space, reflecting the global rearrangement of climatic processes.
