I’ve compiled a list of six examples how the sun impacts climate across the globe.
1. Climate periods based on a double Hale (44-45 years) cycle of solar activity.
In 1977 Australian geologist Rhodes W. Fairbridge found a 45-year periodicity of beach ridge located at the Hudson Bay. It has been formed with storms in Hudson Bay caused by a wavier jet stream.
I have found a 44-year periodicity of heavy snowfall in Japan caused by the wavier jet stream as follows. The time series coincide quite well with that of Fairbridge (1977).
1833 Tempo famine, Dalton minimum (1795-1830)
1877 Seinan war (44 years later)
1918 Rice riot, Gleissberg minimum (1898-1923) (41 years later)
1963 38 heavy snowfall (45 years later)
2006 Heisei 18 year heavy snowfall, Gleissberg or Dalton minimum (43 years)
The climate history of 20th century can be divided with the following 5 periods based on the double Hale cycle above using aa-index of geomagnetism associated with solar activity. The Pacific Climate Shift occurred at 1977 with solar activity increase & a positive PDO index.
1900-1918: Little Ice Age (LIA)
1919-1962: 1st Modern Warm Period (1st MWP)
1963-1976: Temporal Cold Period (TCP, New Ice Age Coming, see below)
1977-2005: 2nd Modern Warm Period (2nd MWP)
2006 – present: New Cold Period (NCP)
