Just a quick note to bring this to attention of readers. I have not been able to locate a copy of this paper other than the paywalled one at Springerlink, so I can’t comment much about it, but it looks interesting. The question is what is the mechanism? The abstract really doesn’t give a hint of that and just saying that “anomalously low solar activity” is the cause really isn’t definitive enough. – Anthony

“We confirm the close synoptic relationship of the sectoral structure of the Sun’s magnetic field of the with the near-Earth tropospheric pressure with a case study of three European points (Troitsk, Rome, Jungfrau) in the period of the anomalously hot summer of June–August 2010.
We substantiate the position that such a relationship was fostered by the anomalously low solar activity as a result of superposition of the minima of the 22- and 180-year cycles. Sectoral analysis of the solar-tropospheric relationships has shown that the appearance of a blocking anticyclone in the Moscow suburbs, its expansion to Rome and Jungfrau, and subsequent retreat at first from these points, and then from the Moscow suburbs was closely related to solar activity phenomena producing, according to contemporary notions, cyclonic activity, shown by simulation of the Earth’s electric field.”
UPDATE: Thanks to readers, I have a copy of the paper, which I forwarded to Dr. Leif Svalgaard for inspection.In the introduction of the paper there is this:
More than 40 years ago, a statistically significant relationship was discovered between the sectoral struc ture of the IMF and the zonal circulation in the atmosphere of the Earth’s Northern Hemisphere; it was suggested that so-called natural synoptic periods to
some degree were determined by the structure of the interplanetary medium (Dimitriev et al., 1978). Recently it was shown that in one important particular case, the anomalously hot weather of summer 2010, a synoptic relationship took place between the sectoral
structure of the solar and interplanetary magnetic field (SMF and IMF), on the one hand, and the surface atmospheric pressure in the suburban Moscow city of Troitsk, on the other (Ivanov and Kharshiladze, 2011).
The Russian paper “confirms the earlier conclusions on the
reality of a relationship between the sectoral structure of the IOMFS and the Earth’s troposphere (Mansurov et al., 1974; Wilcox, 1979; Wilcox et al., 1974;… Wilcox, J.M., Svalgaard, L., and Scherrer, P.H.,

We have long since abandoned the finding as spurious.
So it seems, they are chasing an old discarded theory, and their findings may be nothing more than coincidental – Anthony
