Sentences with phrase «magnetic activity does»

The number of sunspots varies as solar magnetic activity does — the change in this number, from a minimum of none to a maximum of roughly 250 sunspots or clusters of sunspots and then back to a minimum, is known as the solar cycle, and averages about 11 years long.

The big problem is to explain a lag of more than 30 years when direct measurements of quantities (galactic cosmic rays, 10.7 cm solar radio, magnetic index, level of sunspot numbers, solar cycle lengths) do not indicate any trend in the solar activity since the 1950s.

There is no room for complacency, Svalgaard warns: «If the Earth does cool during the next sunspot crash and we do nothing, when the sun's magnetic activity returns, global warming will return with a vengeance.»

There is a «ripple» on the Earth's magnetic field which is assumed to be associated with the «differential rotation» of the liquid Earth's core in respect of the crust (you can google it), which is nothing to do with sunspot activity.

Perhaps not, but solar activity does not follow curve (c): http://www.leif.org/research/HMF-Briffa.png The green curve is solar activity deduced from cosmic ray proxies of the solar magnetic field as carried out to the Earth by the solar wind.

Since 1935, solar physicists have subscribed to what we could call the «eruption theory» where 11 - yr cycle is produced as a unit by a well - developed physical theory that does not rely on excitation of «modes» but on a continuously progressing generation of activity by magnetic induction amplifying existing flux and eventually dying out.

And in fact, that's the basis for this new claim that we might be entering an ice age: if no magnetic activity from the Sun once coincided with a cooling here on Earth, might it not do so again?
