Double-Dynamo Model Predicts 60% Fall In Solar Output In The 2030s
sycodon points out reports of a new model of solar dynamics from University of Northumbria professor Valentina Zharkova, predictions from which "suggest that solar activity will fall by 60 per cent during the 2030s to conditions last seen during the 'mini ice age' that began in 1645."Zharkova's model, based on observation of solar magnetism, "draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone."Zharkova’s and her colleages at three other universities believe that this two-layer model "could explain aspects of the solar cycle with much greater accuracy than before — possibly leading to enhanced predictions of future solar behaviour. “We found magnetic wave components appearing in pairs; originating in two different layers in the Sun’s interior. They both have a frequency of approximately 11 years, although this frequency is slightly different [for both] and they are offset in time.”Read more of this story at Slashdot.
