... In order to disentangle the effects of different climate variables on tree-ring growth rates of different species, and to explore the possibility that more than one species could improve the accuracy of the reconstructions of climate using tree rings, a methodical study of trees in close proximity to the Armagh Observatory climate station was initiated together with Ana Maria Garc?a Su?rez, and continued as part of the latter's PhD thesis with John Butler and Professor Mike Baillie (QUB). ...

... The main periodicity in the Sun 's activity is the 11-year cycle called the solar cycle. ... During the cycle, changes occur in the Sun's internal magnetic field and in the surface disturbance level. ... At the beginning of a cycle the solar magnetic field resembles a dipole which axis is aligned with Sun's rotation axis. ... The sunspot number - and Sun's activity - is at maximum in the middle of a cycle, when the Sun's internal magnetic field is most chaotic. ... Space Physics Text Book of Oulu ...
