Sentences with phrase «polar field reversal»

The second discrepancy occurring during the maximum of solar cycle 24 can be explained in terms of the unusually extended polar field reversal, with both northern and southern polar fields being simultaneously positive for over a year, leading to a higher flux of GCR particles at Earth.

(2), and the polar field reversal around that period.

http://www.ann-geophys.net/30/817/2012/angeo-30-817-2012.pdf Sections 8 and 9 of http://www.leif.org/research/suipr699.pdf show how that relates to polar field reversals.

Not exact matches

The solar polar field [and its reversals] has a signature in the geomagnetic field that be followed back a century.

About the only significant even in the last month is that the solar polar fields have begun their reversal, indicating we are at «solar max», which seems like a misnomer given the low activity observed at the moment.

More precisely, the maximum of solar cycle 24 was characterised by a rather slow and intermittent reversal of the polar field, with north - south asymmetry, meaning that the Northern polar field reversed on November 2012 and the Southern on March 2014, with both polar fields being simultaneously positive for more than a year (Sun et al. 2015).

Systematic differences in the overall shape of successive 11 - year modulation cycles and similarities in the alternate 11 - year cycles seem to be related to the polarity reversals of the polar magnetic field of the Sun.

Hale suggested that the sunspot cycle period is 22 years, covering two polar reversals of the solar magnetic dipole field... The start of the 22 - year cycle begins... This process of sunspot formation and migration continues until the solar dipole field reverses (after about 11 years).
