Important solar cycle landmarks that are influenced by variations in the sun's magnetic field might predict changes in weather patterns and risks to telecommunications. We have been attempting to define the solar cycle using sunspots ever since humanity was able to notice them for the first time
A recent study conducted by Leamon demonstrates that many significant changes during the solar cycle can be accurately described and predicted using a “solar clock” based on the magnetic field of the sun rather than the presence or absence of sunspots. The new approach improves the classic sunspot technique by predicting surges in dangerous solar flares or shifting weather patterns years in advance., specifically demonstrates that the solar cycle functions as a separate sequence of events.
The new paper points to additional landmarks along the journey through a full solar cycle from terminator to terminator. These landmarks are clearer and more consistent than using sunspots as a guide to cycle length. For example, “The max number of sunspots doesn’t quite align with when the polar field reverses, but the polar field reversal happens at exactly one-fifth of the cycle going from terminator to terminator,” Leamon says.
Once the team realized the changes that occur at exactly one-fifth of a cycle, they asked, “How many different solar things can we look at? And then we realized they all overlap on this same set of fifths,” Leamon says. Different parameters shift at different points on the cycle, but “everything is tied to these five landmarks.”
The new framework also puts tighter bounds on the period within the cycle when severe flares are expected, which is useful information for people on Earth. Rather than a gradual shift from minimum to maximum activity, the period from terminator to about three-fifths of a cycle seems to be the peak period for flares, with a rapid drop-off after that point until the next terminator.
