Abstract: Abstract.The relationship between the solar polar magnetic field reversal and coronal hole evolution is investigated for the time interval from 1996 to 2001. The distribution of coronal holes shows some evolutionary changes in relation to the polarity reversals, and these changes appear to be coordinated with changes in the global magnetic field structure, suggesting that the polar reversal originates from global processes. There are periods when the character of the coronal hole distribution on the solar disk… Show more

“…This coincides with disappearance of polar holes; instead, small coronal holes were observed distributed over the whole solar surface (Bilenko 2002). It seems, however, that in 2001 a north coronal hole opened again and some traces of the southern hole appeared as well.…”

“…More detailed analysis of the profiles is beyond the scope of ths paper, since it requires a much more sophisticated modelling. But evidence that our hypothesis is justified is given by Bilenko (2002), who studied the distribution of coronal holes versus heliographic latitude during the past solar cycle-there exist distinct maxima of coronal holes densities at midlatitudies during the solar minimum and transition phases.…”

“…The holes isolated from the poles show an occurrence rate that tends to follow the Schwabe cycle (Insley et al 1995;Luo et al 1997;Hofer and Storini 2003) and they are generally located at the so-called active region latitudes. The majority, but not all, of the ICHs follow the hemispheric polarity rule (they match the polarity of the hemispheric polar field, Bohlin and Sheeley 1978;Harvey and Sheeley 1979;Hofer and Storini 2002;Bilenko 2002). Moreover, some I-CHs show a close connection with active regions during their time evolution (McIntosh 1992;Wang et al 1996;Bravo et al 1998a;Storini and Hofer 1999;Hofer and Storini 2003).…”

“…10). Recently, Bilenko (2002Bilenko ( , 2004 extended the work to 2002 (but the catalogue is not yet available). The extensive use of the catalogues, together with the study of individual holes, led to relevant information for the development of climatological models in the next future, which should be tested with "in situ" observations.…”

“…Several studies have investigated how the long-term CHs evolution is related to the changes in the global solar magnetic field over solar cycle (e.g. Bilenko 2002;Sanderson et al 2003;Wang 2009;Obridko & Shelting 2011). CHs originate in sufficiently large unipolar regions with predominantly open configuration of the magnetic field lines.…”
