since 1750 .]] The Schwabe solar cycle or '''Schwabe-Wolf cycle''' is the eleven-year cycle of solar activity of the Sun . At periods of highest activity, known as Solar Maximum or ''solar max'', Sunspot s appear. Periods of lowest activity are known as Solar Minimum . The last solar maximum was in 2001 . The solar cycle is not strictly 11 years; it has been as short as 9 years and as long as 14 years in recent years. As the image shows, the Solar Constant has varied by about 0.1% or 1 w/m&2 from its mean value of approximately 1366 w/m&2 over the last two solar cycles. The Babcock Model explains the 11 and 22 year cycles as being due to a shedding of entangled magnetic fields. For more details on solar cycles, see the Solar Variation article. |
