en Influence of solar activity on the state of the wheat market in medieval England

The approach was based on the following:

  1. Existence of the correlation between cosmic ray flux entering the terrestrial atmosphere and cloudiness of the atmosphere.
  2. Cosmic ray intensity in the solar system changes with solar activity.
  3. Wheat production depends on weather conditions as a nonlinear function with threshold transitions.
  4. A wheat market with a limited supply (as it was in medieval England) has a highly nonlinear sensitivity to variations in wheat production with boundary states, where small changes in wheat supply could lead to bursts of prices or to prices falling.
