Solar activity predicted to fall 60% in 2030s, to ‘mini ice age’ levels: Sun driven by double dynamo

It is 172 years since a scientist first spotted that the Sun’s activity varies over a cycle lasting around 10 to 12 years. But every cycle is a little different and none of the models of causes to date have fully explained fluctuations. Many solar physicists have put the cause of the solar cycle down to a dynamo caused by convecting fluid deep within the Sun. Now, Zharkova and her colleagues have found that adding a second dynamo, close to the surface, completes the picture with surprising accuracy.
“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, and they are offset in time. Over the cycle, the waves fluctuate between the northern and southern hemispheres of the Sun. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97%,” said Zharkova.

One Response to Solar activity predicted to fall 60% in 2030s, to ‘mini ice age’ levels: Sun driven by double dynamo

  1. reason ”solar activity is predicted to fall” is because: the aparatchiks are looking for a ”backdoor exit” realizing that the phony global warming is just that PHONY, billions squandered – now they are grasping at a straw. YOU DON’T PRODUCE GLOBAL WARMING, EVERY POLITICAL COMMISSAR IN JAIL, FOR LIFE!
